     STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT 
     This application is not the subject of any federally sponsored research or development. 
     THE NAMES OF THE PARTIES TO A JOINT RESEARCH AGREEMENT 
     There have been no joint research agreements entered into with any third-parties. 
     BACKGROUND OF THE INVENTION 
     Solar generation systems and devices for tracking the sun across the sky are known in the art. A number of existing systems use mechanical apparatuses that are designed for small scale output and constrained by a limited number of solar panels. Prior attempts to prepare large utility scale solar tracking systems were poorly designed and unreliable. The solar tracking system described in this application improves upon existing solar trackers by, among other things, utilizing a hydraulically controlled mechanical platform apparatus is designed for large utility scale solar cell mounting and support allowing high energy output, reliability, and durability of the large utility scale solar tracker. 
     SUMMARY OF THE INVENTION 
     The present invention solar tracker system is directed to an large utility scale hydraulically-actuated solar tracker that includes a platform capable of supporting a plurality of solar panels, a sub-platform, and three or more angled support poles converging to an apex for supporting the sub-platform and a linking mechanism that connects the sub-platform to a planar platform, wherein the linking mechanism rotates in a first axis, a second linking mechanism rotates in a second axis. Further, the first axle and the second axle of the linking mechanism are disposed substantially orthogonal to each other and designed to track the longitudinal and latitudinal movement of the sun. The present invention solar tracker system gains operational intelligence and environmental awareness with the inclusion of a local computer system utilizing astronomical algorithms, digital compass, digital inclinometers, one or more solar radiance sensors, and a weather station. The local computer system utilizes software programming to analyze input data from the astronomical algorithms, digital compass, digital inclinometers, one or more solar radiance sensors, and the weather station to activate a movement system to follow the sun arc pathway at given latitude. During inclement weather conditions, the weather station at a minimum, determines the local wind velocity and direction, and by electrical communication with the local computer, adjusts the position of the planar platform surface for maximum energy production until weather conditions dictate a change in normal operational behavior. For example, when the wind exceeds a pre-determined speed which can damage solar cell panels, the movement system activates a wind load mitigation program. When it is raining, to effectively clean the solar cell panels, the movement system attains a rain clean configuration. At night, the movement system positions the planar platform in the horizontal or home stow position. Solar radiation sensors are used for determining the optimum tracking position for maximizing capture of daylight solar energy or moonlight solar energy at night. The one or more radiation sensors function to adjust solar tracking when sun energy is scattered and not direct, due to clouds or other conditions maximizing the capture of solar energy early in the morning hours and late in the evening hours when light is scattered. The large scale solar tracker system also includes at least two linear hydraulic actuators, each linear hydraulic actuator containing a distal end and proximal end, a rotational joint that connects the distal end of the linear actuators to the sub-platform and the proximal end to one of the support poles or support beams of the planar platform. The hydraulic actuators are optionally computer monitored for dynamic operational hydraulic pressures to determine if an unusual load is being imparted on the solar tracker or if a hydraulic actuator is leaking or has failed. The large utility scale solar tracker&#39;s local computer system adjusts the planar platform fitted with the plurality of solar panels by utilizing the hydraulic actuators to implement desired positions of the planar platform for day, night, maintenance, and hazardous weather positions. The linking mechanism, the hydraulic actuators, digital inclinometers and the local computer comprise the movement system. The local computer system also monitors each solar panel for its electrical output parameters and general health condition, and communicates this information wired or wirelessly for remote analysis and monitoring to a remote operations management computer system. The local computer system also downloads weather data, and utilizes the optional local weather station information to move the planar platform with plurality of solar panels into the optimal position to obtain maximum sun exposure and minimize wind propagated stress on the system. The local computer system also moves the planar platform to a particular position during non-sunlight hours. Additionally, the local computer system includes a means for preventing the planar platform from being driven past its mechanical limits.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       FIG. 1  is a perspective view of the present invention improved solar tracker for utility scale solar cell capacity including support structure, a mounting pole, hydraulic actuators, 2 axis gimbal mechanism, planar platform for mounting the plurality of solar cells and including a digital compass, digital inclinometers, solar radiation sensors, weather monitoring station and computer wireless and/or wired electronic communication technology. 
     The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the illustrated embodiments set forth herein. 
     In the following description, like reference characters designate like or corresponding parts throughout the figures. Additionally, in the following description, it is understood that terms such as “first,” “second,” and the like, are words of convenience and are not to be construed as limiting terms. 
     The embodiments of the present invention are directed to one or more Tracker apparatuses  10  for focusing or aiming the plurality of photovoltaic “PV” cells  60  such that the Tracker&#39;s sub-platform  18  and planar main platform  20  are positioned to optimize the capture of energy from the sun for conversion into electricity or other useful forms of energy. The embodiments of the present invention are optimized for solar panel volumes, strength, reliability, efficiency and maintainability. The embodiment also includes a solar radiation sensor  80  on the platform for re-aiming the plurality of PV cells  70  and to reposition and optimize the capture of solar energy when the sun rays are not direct but diffuse, when clouds partially or completely shield the direct sunlight, and when the sun is near the morning or night horizon. The plurality of PV cells  70  are standard PV solar panels fabricated from manufacturers such as Bosch, PB solar, Canadian Solar, China Sunergy, Conergy, DelSolar, Evergreen Solar, First Solar, Kyocera, Mitsubishi Electricity, Panasonic, Schott Solar, Sharp, SolarPark, SolarWorld, SunPower, and/or Suntech, or any other appropriate solar panel manufacturer. The plurality of PV cells  70  are easily replaceable on the Tracker Apparatus  10  so that when one of more PV cells  70  fail, become defective, or lose electrical efficiency. Furthermore, entire series of PV cells  70  can be easily be replaced on the Tracker Apparatus when new more efficient PV cells become available on the market and the user wants to upgrade to the newer PV cells that offer advantages of higher sunlight conversion efficiency. The mounting of the PV cells  70  to the main platform are attached by a custom “T” rail that runs substantially alone the length and width of each PV cell such that the removal of PV cell only requires the removal as few attachment means whereby the entire “T” rail is removed, releasing one entire side of the PV cell  70 . 
     The main platform  20  is shown have a plurality of wind gaps  71  along the length of the sides of and crisscrossing the mail platform  20  which functions to reduce the effects of wind on the main platform  20  with PV cells  70 . Also shown are a solar radiation sensor  80  located near the center of the PV cells. Also shown is an optional digital inclinometer  86  and an optional digital compass  88 . A weather stations  90 , shown in an enlarged format, is shown near one corner. A local computer  100  is shown attached to one of the support poles  16 . It is anticipated by the Applicants that the solar radiation sensor  80 , optional digital inclinometer  86 , optional digital compass  88 , the weather station  90 , and the local computer  100  can be located in various other locations in close proximity to the main platform  20 . Also protruding down from the main platform  20  is one or more support poles  14  with supporting cross-beams  25  and footings shown as solid blocks. It is anticipated that the footing can using other anchoring technology such as helical screws, embedded poles, concrete pads with attachment means. The choice of footing will be dictated by the soil conditions where the Tracker apparatus  10  will be located. 
     A digital compass  84  and digital inclinometer  86  will be used to accurately position the large main platform  20  defined by the local computer  100 . The digital compass  84  is a stable format with high resolution for locating the main platform in a very accurate direction. Digital compass like the Honeywell PC based HMCS883L equipped with magneto sensors provides compass accuracy of 1° to 2°. Other manufactures are fabricated other PCB based digital compasses that can be used with the present invention. The digital inclinometer is an instrument for accurately measuring the scope or tilt of the main platform  20 . Two axis MEMS inclinometers can be precisely calibrated for non-linearity for operating temperature variation resulting in higher angular accuracy over wider angular measurement range. Two-Axis inclinometer, with built-in accelerometer sensors, may generate numerical data tabulated in the form of vibration profiles enable Tracker apparatus  10  to track and assess alignment quality in real-time and verify structure the positional stability. 
     In addition, the Tracker apparatus includes a weather station  90  that monitors wind, rain, sun and other environmental variables. Optionally, the hydraulic actuators  24 ,  26  of the Tracker apparatus  10  can include a pressure sensor  48  for monitoring the condition of the hydraulic system. Furthermore, the Tracker apparatus  10  includes a local computer  100  that communicates wireless and/or wired electronic communication technology to a remote operations management computer or station  110 . The local computer  100  is in electrical communication with the optional hydraulic sensor  48 , the one or more solar radiation sensors  80  and the weather station  90 . The local computer  100  has local control of the Tracker apparatus  10  to automatically respond to environmental and emergency conditions, such as when wind exceeds a defined threshold, or when the solar sensors detect that a modified position of the solar cells would produce more electrical energy. 
     As depicted in  FIG. 1 , in an embodiment of the present invention, the Tracker apparatus  10  includes a three or more support system  12  comprising an series of round members, I-beam cross members, T-cross or similar structural members  14  with foundation mountings  16  (such as screws, concrete or metal foundations) that secure the series of round members, I-beam cross members, T-cross or similar structural members  12  forming the three or more pole structure with angles such that the distal end of the three or more poles meet at an apex  21  that engages the sub-platform  18  to which the large planar platform  20  securing the plurality of solar cell panels is affixed. The support system  12  is comprised of a round member, I-beam cross member, T-cross or similar structural members  14  and a plurality of removable, adjustable foundation mountings  16  (pilings, ground screws, helical ground anchors, or the like). In another embodiment of the present invention, the foundations can be affixed to a large concrete slab. In this embodiment the foundation system  12  comprises a concrete slab with adjustable mountings. This system provides for rapid and inexpensive installations while also providing for inexpensive foundation system  12  that lasts for fifty years of service. The foundation mountings  16  may be adjustable or non-adjustable as needed by atmospheric environmental conditions. The support system  14  can have a series of cross members  17  to serve to provide rigidity for the three or more support poles structures. It is anticipated by the Applicant that multiple series of cross members  17  can be strategically located and engaged to the three or more support poles  14  for increasing the strength and rigidity. 
     The round members, I-beam cross members, T-cross or similar structural shapes forming the one or more support pole structures  14  are preferably fabricated from a metallic corrosive resistant material such as that defined in ASTM A588 steel which defines a high-strength, low-alloy structural steel with atmospheric corrosion resistance. It is anticipated by the Applicant the components of the round members, I-beam cross members, T-cross or similar structural shapes forming the one or more support tubes, or other components of the Tracker apparatus  10 , can be fabricated from a Series 300 stainless steel, (e.g. 304, 316), a cement composition, or high-strength polymeric material. Connected to the series of round members, I-beam cross members, T-cross or similar shapes forming the three or more support tubes  14  are two linear hydraulic actuators  24 ,  26  and a central post section  21 . The first linear hydraulic actuator  24  is preferably designed to cause substantially east-west facing movement and the second linear hydraulic actuator  26  is preferable designed to cause substantially north-south movement. The bottom end of the linear hydraulic actuators  28 ,  30  are distally rigidly connected to the round members, I-beam cross members, T-cross or similar shapes forming the three or more support tubes  14  via bolt and screw, adhesive technology or other connection technology  32  but may optionally include a flexible movement joint mechanism  34 ,  36 . The top end of the linear actuators  38 ,  40  are proximally connected to the sub-platform  18  with proximal with joint mechanism  42 ,  44  using bolt and screw, adhesive technology or other connection technology  46 . These proximally located joint mechanisms  38 ,  40  allow the linear actuators  24 ,  26  to achieve two degrees of freedom of movement, to relieve strain in the linear actuators, assuring proper, free motion of the actuators. The two degrees of freedom refers to a movement that can cause motion in two independent forms such as two orthogonal axes or two orthogonal lines of motion. In the preferred embodiment of the invention shown in  FIG. 2 , the bottom end  22  of the three or more support poles are rigidly anchored to the foundation system  12  where the top end of the support poles  23  converge into an apex  21  which supports a linking mechanism  50 . The top end of the linear actuators is connected to a sub-platform  18 , which holds a main solar cell panel platform  20  that tracks the sun. The main solar cell panel platform  20  is designed to engage and mount a plurality of typical solar cell panels  70 . The linear actuators  24 ,  26  are connected to the sub-platform  18  via a top end joint mechanism  38 ,  40 , and the rigid bottom end connections (or optional bottom end joint mechanism  34 ,  36 ) that allows the actuators  24 ,  26  to achieve two degrees of freedom of movement to relieve any stress forces and assure proper positioning. The linear actuators  24 ,  26  also function as structural members when not in motion. 
     The three or more support pole structure  14  coalesce into an apex structure  21  that is connected to the sub-platform  18  via a two axis gimbal-like linking mechanism  50  that allows the sub-platform  18  and the main platform  20  to rotate around the apex structure  21  with two degrees of freedom. 
       FIG. 2 . demonstrates a top perspective view of the Tracker apparatus  10  showing in more detail the sub-platform  18  and foundation system consisting of one or more support poles  14 , a one or more footings  16 , and some optional cross-beam structures  25 .

       FIG. 3 . demonstrates a bottom perspective view of the Tracker apparatus  10  showing the sub-platform  18  engaging the main platform  20 . Extending below are the foundation system consisting of one or more support poles  14 , a one or more footings  16 , and some optional cross-beam structures  25 . 
       FIG. 4  is a bottom perspective view of the sub-platform with foundation system and cross beam supports with footings. As stated before, protruding down from the main platform  20  is one or more support poles  14  with supporting cross-beams  25  and footings shown as solid blocks. It is anticipated that the footing can using other anchoring technology such as helical screws, embedded poles, concrete pads with attachment means. The choice of footing will be dictated by the soil conditions where the Tracker apparatus  10  will be located. 
       FIG. 5  is a side perspective view demonstrating in more detail the two axis gimbal-like linking mechanism  50  and hydraulic actuators  24 ,  26  cooperating between the main  20  platform and the sub-platform  18 . Due to the length needed for the hydraulic actuators  24 ,  26  to retract and extend, a raised platform is constructed above the apex platform  19 . The main platform skeleton structure is shown with cross bars and corner parts. 
       FIG. 6  is a side perspective view showing the apex platform  19  of the foundation system engaged to the sub-platform  18  which includes a raised platform for supporting the linking mechanism  50  and encompassing the hydraulic actuators  24 ,  26 . The local computer  100  is show in the optional position sitting on the 
       FIG. 7  is a side perspective view showing the main platform  20  angled to the left side of the Tracker apparatus  10  with both hydraulic actuators  24 ,  26  in an extended configuration. The top end  38  of center hydraulic actuator  26  shows a flexible joint  42  and top end  30  of outer hydraulic actuator  24  shows a flexible joint  44  that reduces stress on the attachment and associated hydraulic actuators. Correspondingly, the bottom end  28  of center hydraulic actuator  26  shows a flexible joint  34  and bottom end  30  of outer hydraulic actuator  36  shows a flexible joint  44  that reduces stress on the attachment and associated hydraulic actuators. 
       FIG. 8  is a side perspective view showing the main platform  20  angled to the right side of the Tracker apparatus  10  with center hydraulic actuator  26  in an extended configuration and the outer right hydraulic actuator  24  in a retracted configuration. The top end  38  of center hydraulic actuator  26  shows a flexible joint  42  and top end  30  of outer hydraulic actuator  24  shows a flexible joint  44  that reduces stress on the attachment and associated hydraulic actuators. Correspondingly, the bottom end  28  of center hydraulic actuator  26  shows a flexible joint  34  and bottom end  30  of outer hydraulic actuator  36  shows a flexible joint  44  that reduces stress on the attachment and associated hydraulic actuators. 
     As shown in more detail in  FIG. 9 , a two axis gimbal-like linking mechanism  50  is mounted at the top of the three or more support pole axis  21  and engages and attaches to the sub-platform  18 . Preferably for flexibility, moving joints at the top and bottom of each hydraulic actuator  24 ,  26  are attached at an angle to optimize use of the linking mechanism  50  within their mechanical limits. Flexible joints at the tops and bottom of the actuators  24 ,  26  can optionally have some rotational freedom in addition to what is provided by the free rotation of the actuators  24 ,  26 . 
     Also shown in more detail in  FIG. 9 , a two axis gimbal-like linking mechanism  50  has a defined configuration such that it provides a shoulder  52  for which limits the main platform  20  from moving past a given angle. The two axis gimbal-like linking mechanism  50  at the top of the apex structure  21  is designed to be sufficiently strong to withstand very large torque forces resulting from the weight of the main platform with plurality of solar cells, in a moment from the center axis point. The linking mechanism  50  includes a body member  52  that connects a first axle  54  and a second axle  56 . The first axle  52  and second axle  56  preferably include bearing assemblies  58 ,  60 ,  62 , and  64  that are mounted orthogonal to each other to allow the linking mechanism  50  to achieve a two degree of freedom movement. In the preferred embodiment, the linking body member  52  is fabricated from a strong metallic or cement material with incorporated rigidity members. In addition, the first axle  54  and the second axle  56  can be fabricated from a strong metallic material, such as A588 steel, or series 300 stainless steel. The axle bearing assemblies  58 ,  60 ,  62 , and  64  are preferable fabricated from bronze metallic material. The bronze bearing  58 ,  60 ,  62  and  64  provide a long lasting lubricious surface for the metal axle  54 ,  56  which requires little or no additional lubrication. The linking mechanism  50  is designed to include an offset that acts to assure the sub-platform  20  has sufficient clearance past the three or more support poles  14  and apex structure  21  when the main platform  20  angle is close to the horizon. The fabrication materials and structure is designed to provide minimal strain displacement even under heavy wind loads. However, under extreme wind conditions, the weather station which, at a pre-determined of a wind velocity and direction sensor sensing, will direct the local computer  100  to attain a wind avoidance configuration or the horizontal weather configuration. 
     The orientation of the two axis linking mechanism  50  at the apex  21  of the three or more support post structures  14  is fixed and capable of resisting rotational forces about its center axis. The three or more support post structure  14  itself is also designed to be capable of resisting such rotational forces transferred from the linking mechanism  22 . This resistance keeps the solar tracking apparatus  10  standing erect and in calibration. 
     Furthermore, the mounting of the two axis linking mechanism  50  at the apex  21  of the three or more support post structure  14  at the top of each actuator  24 ,  26  is at an angle to optimize use of the linking mechanism  50  or joint within their mechanical limits. Positioning the lower joint or fastened connection to be high in relation to the foundation is desirable as it improves stability and strength of the solar tracking apparatus for certain angles of the east-west degree of freedom at the beginning and ending of solar days. Additionally, the high positioning of the hydraulic actuators  24 ,  26  helps reduce strain and interference, allowing the solar tracker apparatus  10  to efficiently reach angles required to align the main platform  20  (and sub-platform  18 ) orthogonal to the rays of the sun. The joint members at the top and bottom of the actuators  24 ,  26  can optionally have some rotational freedom in addition to what is provided by the free rotation of the actuators  24 ,  26 . 
     Each Tracker apparatus  10  is self-sufficient as to its core software functionality. Each tracker will have a unique ID and supporting database record structure for performance history. While indexed within a Cluster by an identification number, it is a stand-alone device making it always directly addressable. The solar tracking apparatus  10  is designed for rapid cost effective deployments and scalability. The assembly process is aided by the specific system design in such that multiple assembly steps can take place simultaneously to assemble the components. Simultaneous operations culminate in final assembly wherein a crane (or similar) is used to place the components so that they can be fastened together efficiently. All electronic components in the system are provided with an enclosure for protection from weather and the like. 
     In one embodiment, shown positioned near the center of the plurality of solar cell panels  70 , is the one or more solar radiation sensors  80 , a digital compass  84 , and a digital inclinometer  86 . It is anticipated by the Applicant that the one or more solar radiation sensors  80 , the digital compass  84 , and the digital inclinometer  86  can be placed in other locations in close proximity to the solar cell panels  70 . The one or more solar radiation sensors  80 , the digital compass  84 , and the digital inclinometer  86  are in secure wired or wireless electronic communication with the local computer  100  and function to modify the typical sun arc pathway when the sunlight is not in a direct ninety degree angle to the solar panels  70 , but rather is scattered or diffuse due to such situations as cloudy conditions or in the morning and evening hours when the sun is low in the horizon, and sunlight is not aimed directly at the solar panels. By using the monitored maximum solar radiation measurement from the solar radiation sensor  80 , the local computer  100  modifies the angle of the solar cell platform  20  such that maximum radiation for the plurality of solar cell panels  70  is obtained. It is known that correcting for low horizon conditions, increases the effectiveness of capturing that radiation, thereby increasing tracker efficiency by approximately ten percent or more. The one or more solar radiation sensors  80  monitor the solar radiation and communicate with the local computer  100  to make real-time corrections. So when scattered clouds obscure the sun periodically, the solar radiation sensors  80 , together with the local computer  100 , can make appropriate corrections in the platform  20  angle to maximize capturing solar radiation resulting in a maximum solar capture configuration  82 . Some manufactures of solar radiation sensors  80  are Apogee Instruments located in Logan, Utah and Davis Instruments located in Hayward, Calif. 
     In another embodiment, the MLD (maximum light detection) principle relies on tracking the solar module to the most energetic solar point in a manner that is as quick, precise, and as energy-saving as possible. This is a function of the control module, an acrylic pyramid (tetrahedron) with an edge length of 80 millimeters. 
     The control module continually measures the intensity and angle of incoming light beams and aligns the solar module platform accordingly. The module takes account not only of the radiation from the sun, but also light reflected by snow, water or light-colored rock or diffused radiation that penetrates clouds. 
     Two sensor cells provide reference values, which are processed and evaluated by the integrated logic chip of the control module. A differential amplifier controls the transition from the logarithmic characteristic curve during strong radiation to a linear characteristic curve during low currents, as caused by diffuse light. Because of this, the systems produce a relatively high yield, even with weak radiation. For the linear characteristic curve, the logic chip accepts a much higher value than for the logarithmic curve. This results in a significant increase in the readjustment precision with decreasing brightness. The differential voltage is additionally impinged with a load, whereby the shutdown threshold is extended up to some 30 watts per square meter, and thus into twilight conditions. 
     A third sensor cell on the rear of the control module ensures that the solar cell platform automatically faces the sunrise in the morning. To prevent both hydraulic drives from moving at the same time in dual-axis systems, sensor control system is designed so that the east-west drive has priority over the elevation. Each dual-axis tracking system could be equipped with one or more control modules. 
     Because of the automatic tracking of each individual system, which is a special feature of the present invention compared with astronomically guided tracking utilizing a central control system, as well as wiring up the solar farm with data cables, is not necessary. This has considerable effect on the cost effectiveness of solar farms. With varying and quickly changing cloud conditions, for example, the present invention control modules always independently move each tracker system in the entire solar farm deployment to the optimum solar energy collection position. This means that each unit achieves the highest possible energy yield. 
     There is also a safety aspect. If the on-board tracker sensor control should fail, it is always just one system that is involved as the other units in the solar farm deployment continue working normally. 
       FIG. 10  is a side perspective view showing the main platform  20  angled to the left side of the Tracker apparatus  10  with center hydraulic actuator  26  in an extended configuration and the outer left hydraulic actuator  24  in a retracted configuration. 
       FIG. 11  is a side perspective view showing the main platform  20  angled to the right side of the Tracker apparatus  10  with outer hydraulic actuator  24 , and center hydraulic actuator  26  in an extended configuration. 
       FIG. 12  shows a more detail view of the weather station with wind velocity and direction monitoring apparatus. Shown near the side of the plurality of solar cell panels is the weather station  90 . It is anticipated by the Applicant that the weather station  90  can be placed in other locations in close proximity to the solar cell panels  70 . The weather station is in wired or wireless electronic communication with the local computer  100  and functions to modify the main platform  20  when environmental conditions warrant. The weather station  90  has a wind monitor that measures the wind velocity and angle on a real time basis. This information is communicated electronically to the local computer and if the programmed software senses that the wind velocity exceeds a given value, the main platform  20  can be positioned in a defensive configuration to minimize damage to the system. The weather station  90  can also monitor the local ambient temperature, barometric pressure and humidity. The weather station  90  also may have an electronic communication means with the internet and weather satellites to download weather data and information that might be useful for the Tracker apparatus  10  to modify the are and angle of the main platform  20  in response to environment conditions. 
       FIGS. 13 and 14  show a perspective view typical sun arc pathway  120  showing the advantage of the present invention solar radiation sensor technology  80  improving the efficiency of solar absorbance when sunlight is scattered and diffuse during periods of partial or complete clouding that shields the sunlight, or when the sun is near the morning or night low horizon. Using the solar radiation sensor  80  to modify the typical sun arc pathway when the sun light is not in a direct ninety degree angle to the solar panels  70 , but rather is scattered or diffuse due to such cloudy conditions or during the morning and evening hours when the sun is low in the horizon, and sunlight is not aimed directly at the solar panels. By using the monitored maximum solar radiation measurement from the solar radiation sensor  80 , the local computer  100  modifies the angle of the main platform  20  such that maximum radiation for the plurality of solar cell panels  70  is obtained. It is known that by correcting for low horizon conditions, an increase in the efficiency of capturing the radiation during these periods, an increase in the efficiency is approximately ten percent. The solar radiation sensor  80  monitors the solar radiation and communicates with the local computer  100  to make real-time corrections. So when scattered clouds obscure the sun periodically, the solar radiations sensor  80  together with the local computer  100  can make appropriate corrections in the main platform  20  angle to maximize capturing solar radiation resulting in a maximum solar capture configuration  82 . 
     Shown in  FIG. 15  is a perspective view with the main platform  20  in a wind avoidance configuration  92 . In this wind avoidance configuration  92 , the local computer  100  reads the wind speed and direction from the weather station  100  and positions the main platform  20  with the plurality of solar cell panels into the wind (with the front glass surface of solar cell panels  70  facing the wind) which is then tilted into the wind so that the main platform  20  with plurality of solar cells  70  is angled down in a range of 2-18 degrees and in a more specific range of 5-8 degrees from the horizontal axis and into the wind. 
     In extreme conditions, the main platform  20  with plurality of solar cells  70  may be positioned in a flat horizontal configuration  96 . There exist edge disrupters along the perimeter edges of the planar platform with the plurality of solar panels, with the expressed purpose to disrupt wind flow across the planar platform, defeating wind pressure buildup. There is designed channel spacing within the arrangement of mounted solar panels, which bleed off wind pressure buildup during variable or sustained periods of extreme weather conditions. The weather station will regularly update the local computer on relevant conditions, such that the local computer will analyze conditions-over-time to properly determine the correct next action(s) given current time-of-day. 
     The weather station  90  can predict from downloaded weather data or may also have a moisture/water sensor such that when the plurality of panels is exposed to rain conditions, the local computer  100  instructs the movement system to rain wash configuration  94  which will range from 40 to 48 degrees from the horizontal axis (See  FIG. 16 ). Solar cell panels  70  do collect dust and dirt on the glass surface so a periodic washing maintains their solar capture efficiency. But once cleaned, additional washing will have little effect on the efficiency, so the weather station wired or wireless electronically communicates with the local computer  100  which has algorithms and software instructions to only enter the rain clean configuration when it is necessary, or when opportunistic conditions warrant. Optionally, an optical sensor can be utilized to measure the amount of dirt and debris on the glass covering of the solar cell panels  70  to better understand efficiency degradation, thereby triggering software instructions to hunt for the next potential rain wash configuration opportunity. 
     A maintenance configuration  94  is similar to the rain wash configuration but this is selected by a hard or soft button, switch, or other technology that causes the movement system to enter a range from 38 to 50 degrees, and more specifically from 40 to 48 degrees from the horizontal axis for maintenance, repair, replacement or other corrective action associated with the solar cell panels  70 . The hard or soft button, switch, or other technology causing the movement system to become active can be located on the local computer  100 , the remote operations management computer  110  or both. 
     The local computer  100  is in secure wired or wireless electronic communication with the one or more solar radiation sensors  80 , the weather station  90 , the digital compass  84  and the digital inclinometer  86 . The local computer  100  is also in secured wired or wireless electronic communication with a remote operations management computer  110 . The local computer is located near and engaged with the one of the structural support poles  14 . It is anticipated by the Applicant that the local computer  100  can be placed in other locations in close proximity to the solar cell panels  70 . The local computer can have a display  112  and a keyboard  114  for an individual to review parameters for the tracker apparatus  10 , the solar cell panels  70 , or the hydraulic actuators  24 ,  26  or for download or upload software instructions. The local computer  100  take information from timing, sensors and environment variables and can send commands to change the angle and configuration of the main platform of the Tracker Apparatus. 
     The Tracker apparatus  10  will utilize inputs from the defined location, time of day, date, GPS coordinates, digital compass, digital inclinometers, solar radiation sensors, environmental sensors, known astronomical solar calculations, and foundation orientation to govern the movement control system. The local computer  100  will use these inputs and/or calculations to acquire several sets of solar position angles for a given time and day. The local computer  100  will have programmable software instructions to perform the designed operational characteristics for controlling the movement control system. There are several operational stowing (STOW) positions required, so these are defined below. Most refer to a physical resting position for the Tracker&#39;s Array Table. 
     H OME  S TOW —normal, nighttime resting position that expect to find Trackers at end-of-service-day. Defined as 0° Pitch (Y-axis) and 0° Roll (X-axis) parallel to the ground. 
     E MERGENCY  S TOW —action used to describe the condition where immediate movement back to H OME  S TOW  position is mandated. Typically triggered by an adverse weather situation, that is emerging unrelentingly. 
     Assume action results in a H OME  S TOW  orientation reached within a few minutes to minimize a rapid wind pressure change, without incurring damage to the Tracker&#39;s PV panels, hydraulics or support structure. 
     W EATHER  S TOW —pitched position reached after re-zeroing to H OME  S TOW  orientation to defeat wind pressure buildup. Would typically be in a “pitched down” position, several degrees into the direction of an emerging weather condition, typically seen as high winds. Pitched directional orientation to be updated over time as the conditions warrant. 
     M AINTENANCE  S TOW —this is a triggered condition by on-site personal&#39;s need to perform either scheduled or unscheduled Tracker maintenance. Tracker in “off-line” condition. 
     Typical situations would be panel cleaning, replacement, or wiring diagnostics. 
     These would cause Array Table to be positioned at a 48° maximum downward tilt in the appropriate quadrant needing attention. Array resting on any two (2) legs. 
     Could also be a “stand-down” condition when maintenance service cycle exceeds a daytime work day, so Tracker unusable until further notice. 
     O PERATIONAL  D AY —normal, nighttime resting position that expect to find Trackers at. 
     P RODUCTION  D AY —normal, nighttime resting position that expect to find Trackers at. 
     The movement control system can make use of polynomial spline curves, data tables, solar calculation in real time, or series of rules combined with actuator positions translated from standard elevation and azimuth angles, that are adjusted by the one or more solar radiation sensors and environmental sensors, to drive the linear actuator  24 ,  26  positions. In the case of using data tables, solar calculations taken in real time or series of rules together with actuator positions translated from standard elevation and azimuth angles, the use of spline curves are not necessary. When using spline curves that are created by taking multiple known angular positions of the sun during the day and translating those angles into linear actuator  24 ,  26  positions based on the a relationship between the angular positions of the sun and the mechanical configuration of the Tracker apparatus  10 . The linear actuators  24 ,  26  and their relative positions become data points for the creation of the spline curve which is a function of the “T” variable of time from sunrise to sunset. Additional spline curves are also used to map the angles of the linking mechanism  50  and axles  54 ,  56  and the time-function ratio of those angular positions and angular velocities are related to the linear positions and velocities of the actuators  24 ,  26 . The local computer  100  located on each Tracker apparatus  100  is capable of calculating these spline curves overnight for the next day&#39;s use using previously stored data. In the case where a central computer is used to calculate the spline curves, data tables, real time solar calculations, or series of rules together with actuator positions translated from standard elevation and azimuth angles for all the Trackers apparatus  10  in a cluster  112 , or scalable utility field area  114 , each Tracker apparatus  10  has the ability to store a data table. Alternately, each solar tracker could be equipped with sufficiently large memory capacity to store up to several years&#39; worth of information that is periodically downloaded from a remote operations management computer  110 . 
     The present invention can utilize spline curve method for building the movement control system. This is because the mathematics of real-time solar calculations and their respective derivatives require much greater computational power and generates a significant error. This leads to an increase in hardware costs and reduces the accuracy and stability of the movement control system. 
     In a preferred embodiment, the spline curve method provides for incremental adjustments to the actuator  24 ,  26  velocities throughout the day with position adjustments being continuous. 
     The movement control system provides very accurate and smooth control for the linear actuators  24 ,  26 . This control strategy minimizes or eliminates overdriving of the actuators  24 ,  26  which reduces wear and strain on the actuators  24 ,  26  and other mechanical components and minimizes the electrical current draw and energy use. 
     The linking mechanism  50  and hydraulic actuators  24 ,  26  are required to continuously modify the movement control system and relay this data to the local computer  100 . Environment factors (temperature, wind velocity and direction), solar radiation sensor information and changes in friction adjust the hydraulic actuators  24 ,  26  until the actual position matches the proper position. 
     The main platform panel  20  in a severe weather, home stow, or night stow mode configuration  98 . The severe weather, home stow, or night stow mode configuration  98  is flat and parallel to the horizontal axis. 
       FIG. 17  is a Venn diagram graphic view of the software&#39;s operational functional modules  120 , along with their respective core feature sets. The Venn diagram graphic shows all possible logical relations between finite collections of different feature sets of the software for the Track Apparatus  10 . The local computer  100  or the remote operations management computer  110  will induce functional code for feature components and will communicate using the operational access point  122 . During the installation process, each solar tracker apparatus  10  will undergo a certification process. If a major maintenance situation occurs, it is assumed that the Tracker will undergo a re-certify process verification stage, before returning to fully qualified service duty. 
     For the purpose of implementing the functional modules identified in the Venn diagram, there will be three operational modes, namely, an On-Site Control, an On-Board Control, and a Remote Access Control mode. The On-Site Control mode is utilized primarily to assist in the final assembly and erection of a single solar tracker system intended to confirm full feature functionality prior to placing system on-line for energy production. This could be a wired umbilical connection  134  providing local control over any and all operational characteristics of the solar tracker system. Once certified for full operational use, solar tracker system will switch to the On-Board Control mode where the local computer has full command of all operational characteristics. Finally, wired or wireless communication with the operational solar tracker system is achieved through the Remote Access mode. 
     On-Site Control mode is achieved through the use of a dedicated computer containing software instructions and coded algorithms to accomplish the task of boot-strap startup and information aggregation via these services: 
     Localized weather aware database informational lookups and historical table indexing, which includes the initialization and status monitoring of all sensors; 
     Sending over-ride response instructions as local weather conditions, range of operation, and installation startup conditions warrant; 
     Provide the various network administration setup and configuration routines to properly profile the wired and wireless addresses within the solar field implementation; 
     Provide localized view of operational performance by aggregating system into it&#39;s Cluster, Quadrant, or Block assignment as requested and required; 
     Provide internet testing and verification of access conduit drill-down in support of various view perspectives demanded by the Operational Management Dashboard GUI. 
     Remote Access control mode designates the condition where any operational movement and/or informational queries or commands, occur with wired or wireless connection(s) when not on site. Since this is now a solar tracker system in a fully functional local operation state, there is no need for anyone to perform any movement command remotely after a Tracker is formally certified. On-site personnel will initiate any specific Tracker motion command, a much safer paradigm. Therefore the software Operations Oversight (OPS) module needs only to be a web aware application. 
     Additionally, the Applicant may maintain the communication channel, depicted on the Venn diagram as an Operational Access Point (OAP), which will exist and will be utilize for the purpose of providing dynamic status information only. This allows for discerning root cause origin of any problem thru understanding real-time and historical performance characteristics. At a minimum, the solar tracker system is expected to provide the following when queried via this mode: 
     The current operation status and configuration parameters of all sensors and monitoring devices, along with their respective historical performance parameters; 
     The unique identification badge label such that each system can be individually or collectively grouped into performance metrics profiles. 
     It is deemed highly possible a more substantive information stream will flow available to this OAP portal, providing background performance monitoring for the purposes of garnering a deeper understanding of the actual operational behavior and environmental response characteristics that occur at various installed latitudes across the globe. Applicant foresees the opportunity to provide an information-as-a-service (IAAS) feature with future solar tracking system installations, both as a real-world design check validation via the creation of a real-time performance database, and in concert with a structured operational metrics package that assists or enhances the Customer&#39;s ownership experience. 
     The Operational Day Boundary is defined as Midnight for the formal start/end of an operational day. This will map with existing worldwide time zone definitions and astronomical conventions currently used, along with simplifying the data mining efforts toward assuming how to properly calculate a day&#39;s performance parameters. 
     The Production Day Boundary is defined as the time period from 5 a.m. to 9 p.m. which will be used for the formal start/end of a production day unless moonlight tracking is initiated. It will be assumed that the Tracker apparatus  10  is “out-of-service” in a Home Stow position during the hours of typical darkness. This Home Stow position is expected to be after daily solar production, beginning no later than 9 p.m., until before the start of new daily solar production, expected to begin at 5 a.m. 
     Shifting the data reporting to this day boundary will allow a more accurate Tracker behavior profile reporting picture of hours-out-of-service via the hours-in-service. An annual adjustment for Sun&#39;s arc path, which affects available daylight, is expected. 
     For Customer Grid Integration, the Customer will be required to properly understand exactly how the Grid interface “hand shake” will occur. It is possible that the Customer will require nothing more than what is planned and developed as a SCADA (Supervisory Control and Data Acquisition) compliant OPS Performance oversight functional module, utilizing their existing management control applications once the power generation is connected to their Grid. 
     Occasionally internet access issues to be resolved during extended service life, but Initialize/Certify/Maintenance stages don&#39;t require web based mirrored application versions. These are to be utilized in a comprehensive menu package, launched as needed dependent upon the specific stage of Tracker development encountered. Each Tracker apparatus  10  certifies a specific Cluster each day or during a specific time period. The Maintenance/Certify module  126  feature set will remain functionally equivalent for any and ah field deployed Trackers apparatus  10 . GUI will allow drill-down functionality into each Tracker data base utilizing MW Block naming scheme already devised. The OPS Oversight module  128  will provide base feature functionality. If two (2) or more Trackers are commissioned at this stage, additional requirements to review their operation now exist with both acting as separate 100 MW Blocks deployment for aggregated performance reporting. The OPS Oversight Module  128  will require drill-down functionality for base feature functions of a single Tracker; then aggregated performance for a Cluster, then MW Block configurations. The customer integration module  130  is only needed once the Production stage is fully implemented. Direct connection to local power Grid can occur without software oversight. Simply providing access to OPS Oversight  128  performance will suffice until final Customer Integration requirements are mutually defined. The following will provide a more detailed description of the computer modules. During the “Start-Up” procedure, the Tracker Apparatus  10  is designed to directly address the initial construction of a single tracker, examining the Tracker construction process to verify operational readiness. 
     As shown in  FIG. 17 , there are four distinct operational functional modules which interact and remain interdependent within specific configuration limits, as shown via the Venn diagram, to propel Applicant&#39;s solar tracker system from kitted parts into a fully functional solar radiation energy generator. These four modules provide the features making this invention an operationally intelligent yet environmentally aware system. 
     The first module, referenced as INITIALIZE MODULE  124 , is designed to address the initial construction of a single tracker, and examining the Tracker construction process. Various sub-modules and software sub-routines associated with the Initialize Module  124  include PCB initialization  138 , string power up  132 , umbilical connect  134 , Tracker device identification and coding  136 , database integration  138 , inverter connect  137  and Pen &amp; TR operations  139 . Verification of the initialize module  124  operational readiness via the features sets is provided below. 
     Base initialization of local computer&#39;s PCB from cold boot  138 , which includes the need to prove active available DC power, driving a defined sequence toward power-on-self-test (POST)  132 . Additional elements needed, but not limited to, will be sub-routines designed to verify the BIOS state, battery voltage levels coupled with drain current, and followed by atomic clock initialization routines that support GMT synchronizing. 
     Next follows critical need to determine and establish initialization of key communication components which support Wi-Fi protocols, send/receive bit transmission packet protocols, and web ‘http’ stack layers. 
     Device identification badge assignment is required, followed by initialization routines for database generation for pending information storage. 
     Launch instructions for the pan and tilt movement control sub routines commence, resulting in the ability to test base operational range-of-motion and acknowledgement of maximum tilt service failure stop. 
     Launch instructions for base initialization of hydraulics operations, which includes tests for operational range functionality and responsiveness. 
     Software instructions now test the existence of all the umbilical connections used for both power &amp; communication links with on-site personnel. 
     Subroutines are initialized for the purpose of powering up, sequencing and testing the solar panel sting combiners in each of the numerous rows of panels arranged into functional strings on the planar platform. 
     Now initialization routines that drive the interface instructions for Inverter power connections launched and activate themselves to OEM protocols. 
     Initialization sequencing process will complete after successful termination of all segments above, resulting in the final verification of the Tracker&#39;s kW capacity output levels. 
     The second module, referenced as CERTIFY MODULE  126 , is designed to directly address the need for a Day-Of-Operation performance condition prior to formally handing off ownership of a completed Tracker system. Various sub-modules and software sub-routines associated with the Certify Module  126  include wake-up and shut-down  148 , range of motion  150 , 24 hour initialization  151 , cluster power connect  152 , 3 rd  power connect  154 , wind/Wx  156 , end-to-end functionality  155 , and hydraulic status  158 . Full power production and unattended operational compliance must be established and verified. This should be completed within 24 hours, initiated any time prior to Sunrise following either an initial construction phase or service re-introduction promotion following a maintenance cycle, to properly examine a Tracker validating its operational readiness via the following features sets: 
     Subroutines for triggering the standard daily Wake-up and Shut-down  148  conditions within an operational 24 hour period will be included. 
     Full range-of-motion  150  depicting all possible duty cycle conditions will be introduced, as these motion flex points will be tested both within an typical operational day horizon, periodically bracketed with various motion test routines to validate designed range-of-motion. 
     All the grid power connections  152 ,  154  will be examined, both for the existence of current load(s) and current flow rates bracketed by design expectations. 
     A full battery of operational conditions will be applied to examine the hydraulics&#39; responsiveness  158 , which will include but are not limited to, typical day range-of-motion performance curve; the emergency stow sub-routine&#39;s speed, response time, and force at conditional hand-off; sensor performance readings address viscosity levels, pressure ramp-up vs. bleed-down rate, and true hydraulic throw distance. 
     Testing verification of full Day-of-Operation&#39;s performance characteristics from sunrise to sunset, and all the metric data produced against design specifications with the goal to verify nominal performance curve. 
     Full and robust test suite that properly verifies and confirms nominal performance of the Astronomical and Hot Spot algorithms, coupled with back-tracking subroutines, as needed. 
     Robust testing of adverse weather conditions will include, but not limited to, the trigger, non-trigger, and threshold conditional parameters against their responsiveness curve actuals vs. acceptable time lag tables we&#39;ve designed. 
     Aggregate actual performance characteristics for all the remaining onboard sensor&#39;s functionality and time lag responsiveness for temperature, humidity and irradiance detection. 
     The third module, referenced as MAINTENANCE MODULE  141 , is designed to directly address the field needs of each specific Tracker. Various sub-modules and software sub-routines associated with the Maintenance Module  141  include PM cycle  144  and clean and replace  146 . Operated by a single individual, via a wireless or direct umbilical connected computer, allows the performance of any required maintenance followed by engagement of any operational feature set combination itemized above, from either the INITIALIZE or CERTIFY MODULES. Tipping in any direction allows easy access to any main planar platform quadrant across all four possible axes (North, South, East or West) and will support any of the following conditions in either a preventative or event driven maintenance situation. 
     Standard service-life tasks for preventative maintenance (PM) duties that may need to be performed, such as but not limited to, the hydraulic actuators, operational fluid replacement, PV solar panel service or replacement, wiring loom or hub connectors, racking connections, or general cleaning. 
     Structural repairs and or component replacement, to include the ability to activate an electro-mechanical cut-off switch to remove Tracker from any energy grid production contribution. 
     Intentional action to take Tracker off-line, as conditions warrant, where the Maintenance Stow position is invoked until such time as required parts or scheduled become available to fully complete scheduled or unscheduled maintenance activities. 
     The fourth module, referenced as OPS (OPERATIONS) OVERSIGHT MODULE  128 , is designed to directly address the daily need to functionally operate the Tracker Apparatus  10 , Cluster configuration and MW Block field configurations. Various sub-modules and software sub-routines associated with the Operations Oversight Module  128  include astronomical tracking  170 , hot spot tracking  172 , performance metrics  160 , service functionality  129 , fault tolerant  166 , weather and wind aware  164 , and emergency stow  162 . A GUI design will allow drill-down into various aggregated performance views, depending upon which functional perspective is required. Therefore the software OPs Oversight module is a web aware application. 
     Operational oversight may exist in the form of starting at a top-level perspective, aggregating performance information into an easily understandable presentation, followed by subsequent drill down perspectives to reveal more finite operational groupings (clustering) to improve discrete identification of specific performance behaviors. This could take the form of high level color coded status flags, signaling the various operational states currently implemented. Examples, but not limited to, could occur if an extended Maintenance situation is active, or if emergency stow actions are underway, or energy performance curves are being effected by current weather conditions. 
     This last identified module, depicted as adjacent to the OPS OVERSIGHT MODULE, is defined to be Customer Integration which—is designed to directly address the situation where the Customer wants 100 MW Block performance data, provided either as structured data packets or data on-demand (via system hooks), into the OPS Oversight module, a SCADA compliant application. Direct mating to the Customer&#39;s existing grid management application(s) will be provided via SCADA protocols. Lower level direct mating from inverters coupled to Customer&#39;s transformer will also be possible, when information conditions warrant. These direct mate informational requirements in no way prevent the Customer from using the Ops Oversight module as a secondary, stand-alone performance monitoring solution. 
       FIG. 18  is perspective graphical user view (GUI) of the plurality of Trackers that result in a 100 mega-watt [B LOCK  V IEW ] energy production. This figure is exemplary and it is anticipated by the Applicant that more or less tracker apparatuses can be used for energy production. Shown in this Figure are an exemplary of forty-four tracker apparatuses  10  arranged so each tracker apparatus  10  is electrically coupled to each other. It is anticipated by the Applicant that the large utility field will include approximately 1,000 Tracker apparatuses  10  comprising a large block utility scaled field designed to produce approximately a gross power capacity of 100 megawatts, and approximately 4,000 Tracker apparatuses comprising a large square utility scaled field, designed to produce a gross power capacity of approximately 400 Megawatts. The system is arranged so each tracker apparatus  10  has a unique, defined identification number. The plurality of tracker apparatuses  10  are electrically coupled to a utility scaled electric grid. Selecting any numbered Tracker apparatuses icon will cause a drill-down experience to reveal a detailed view and related performance characteristics of that cluster. 
       FIG. 19  is a perspective GUI view [C LUSTER  V IEW ] of the Tracker Operations Management Dashboard  180  having a 1 Megawatt (the output of a cluster is 115 kW×9=1.035 MW) view of Tracker monitoring of electrical parameters. A cluster design is a function of selected Inverter capacity, currently thought to be supporting nine (or a range of 7-12) tracker apparatuses placed near each other in a specific pre-determined manner to eliminate or mitigate shadow casting between tracker apparatuses with each tracker output feeding into one (1) common inverter thereby allowing the cluster to work as a unit. In this exemplary view, the output of the cluster is 1.035 Megawatts. In this dashboard GUI view, shown is a weather pane  182 , a cluster overview pane  184 , a real-time power gauge pane  186 , a real time system pane  188 , daily power graph pane  190 , real time line voltage pane  192 , a daily energy over a month period pane  194 , a monthly energy, over a year period, pane  196 , and a graphic depiction of the cluster trackers apparatus  200 . This figure is exemplary and it is anticipated by the Applicant that more or less panes can be used for comprehensive performance oversight in a cluster view. Additionally, there is depicted a drill-down (lower right corner) and drill-up (upper left corner) panes assisting the ability to drill-down to a specific Tracker perspective, or drill-up to the parent Mega-Watt Block view. Furthermore, the exemplary figure can include additional panes or replace some of the existing shown panes. It is also anticipated by the Applicant that the panes of this GUI view Dashboard can be customized by the user. 
       FIG. 20  is a perspective GUI view [S INGLE  V IEW ] of the Tracker Operations Management Dashboard  230  having a 100 kilowatt single view of Tracker monitoring elements of electrical In this exemplary dashboard view, shown is a weather pane  232 , a % power pane  234 , a system overview pane  236 , a real-time system power gauge pane  238 , a current weather pane  240 , daily power graph pane  246 , daily inverter temperature pane  244 , real time line voltage pane  242 , a daily energy over a month period pane  248 , a monthly energy, over a year period, pane  250 , and a graphic depiction of the cluster trackers apparatus  260 . This specific pane assists in the ability to quickly drill-up to the parent Cluster view. This figure is exemplary and it is anticipated by the Applicant that more or less panes can be used for this GUI view. Furthermore, the exemplary figure can include additional panes or replace some of the existing shown panes. It is also anticipated by the Applicant that the panes of this cluster view Dashboard can be customized by the user. 
       FIG. 21  is a perspective GUI view [E NVIRONMENTAL  V IEW ] of the Tracker Operations Management Dashboard  270  showing the tracking of critical environmental variables. Shown in this figure is a current weather pane with current temperature with daily high temperature, low temperature, record high and low temperature pane  272 , and center pane having the cloud conditions  274 , wind conditions  282 , rain conditions  285 , and current humidity and barometric pressure  284 , UV index pane  286  Almanac pane  290 , and solar radiation pane  29 . The left side pane shows the temperature summary  280  and a cloud base pane  281 . The right side panel show a weather dashboard pane  276  and shows the 7 day weather forecast  278 .
