     DETAILED DESCRIPTION 
     Many refrigerated containers are fitted with or coupled to a generator, such as a diesel generator, in order to provide power. However, diesel generators are a source of carbon exhaust pollution and must be periodically refueled. The refueling process can take time and inconvenience a truck driver during shipment. Thus, what is needed is an efficient, clean power source for a refrigerated container. 
     The present disclosure provides systems and methods for providing power to refrigerated systems without requiring regular refueling. In particular, the present disclosure provides a solar power system for use in transport vehicles, containers, and trailers. A solar power system does not require refueling in order to generate electricity because it draws its energy source from solar radiation. Transport vehicles, containers, and trailers can spend large amounts of time exposed to solar radiation during the transport. Thus, providing a transport vehicle, container, or trailer with a solar power system capable of powering a refrigerated vehicle, container, or trailer can be beneficial for the efficient transportation of refrigerated goods. 
     I. Overview 
       FIG. 1A  illustrates a solar power system  100  that can be implemented on a transportation system  110 . The transportation system  110  can include any suitable transportation vehicle or container, such as a truck, a truck trailer, semi-trailer, cargo trailer, work boat, cargo boat, freight train, a cargo container, or other vehicle or container. For example, the transportation system  110  can include a truck  120  and a refrigerated trailer  121  for use in shipping perishable freight. Other applications for the solar power system  100  may also be possible. For example, the solar power system  100  can be coupled to a non-commercial mobile vehicle, such as a pleasure boat, recreational vehicle (RV), golf cart, or mobile home. In another example, the solar power system  100  can be applied to non-mobile or semi-mobile structures to enable off-grid or semi-off grid power supply. In another example, one or more aspects of the solar power system  100  may be applied to portable structures or objects, such as backpacks, tents, stands, or other portable and/or temporary devices or structures. In another example, the solar power system  100  can be connected to provide power to a vehicle lift gate, HVAC unit, trickle charge batteries, lighting after or during catastrophic events (tornados, hurricanes, earthquakes, storm aftermath, floods, water purification, community food preservation, electrical blackouts, etc. 
     The solar power system  100  can include one or more solar packages  111 . As described in more detail below, the one or more solar packages  111  can include any number of components. For example, the one or more solar packages  111  can include a support system or layer designed to help prevent damage to solar cells due to road vibrations or other vertical shocks that can occur during transport. In some examples, the one or more solar packages  111  can include a reinforcement material  220  that may provide rigidity or reinforcing structure, be conductive and/or improve the efficiency of the solar power system  100 . The one or more solar packages  111  can include a protective or encapsulating layer that can help prevent damage to solar cells due to damage that can occur during transport of the trailer or container upon which the solar power system is disposed. 
     The solar power system  100  can be disposed on the transportation system  110  at the time of manufacture or through a retrofitting. For example, the solar power system  100  can be disposed on the transportation system  110  by applying one or more solar packages  111  to a sun-exposed surface  130  using an adhesive, as described below. The one or more solar panel packages  111  may be covered in an encapsulating layer  210 , as described below. 
     During a manufacture or retrofitting process, the solar power system  100  can be electrically connected to one or more components of the transportation system  110 . For example, components of the transportation system  110  can require a power source (for example, a refrigeration system  126 ). The solar packages  111  of the solar power system  100  can be electrically connected to components of the transportations system  110  that require power. In another example, the solar packages  111  can be electrically connected to a battery system  124  for storing power. Other electrical connections to and from components of the solar power system  100  can also be made at vehicle manufacture or during retrofitting. For example, electrical connections to one or more power components  122  can be made during a retrofitting process. Some electrical connections can be made before the retrofitting process and some electrical connections can be made during the retrofitting process. For example, the solar packages  111  can be connected to one or more power components  122  at manufacture of the solar packages  111  and the solar packages  111  can be connected to a battery system  124  during a retrofitting process. In another example, the solar packages  111  can be connected to the one or more power components  122  and the battery  124  during one or more steps of a retrofitting process. 
     A transportation system  110  may include one or more components such as a truck  120  or refrigerated trailer  121 , a refrigeration system  126 , and at least one sun exposed surface  130 . In some examples, a transportation system  110  and/or solar panel system  100  can include some combination of power components (for example, one or more power controller components  122 , a display system  123 , and/or a battery system  124 ), 
     The one or more power components disposed on a transportation system  110  can include some combination of energy storage, power converters, power regulators, power generation components or other suitable components for generating, regulating, or manipulating power. For example, the power components can include one or more solar charge controllers, such as a Schneider Conext™ 60 Amp MPPT Charge Controller 21-60 VDC. The charge controller can include one or more temperature sensors and may have a maximum input of 150 VOC. The power components can include one or more surge protectors, such as a MidNite Solar MNSPD-115 115 VDC 90 VAC Lightning Arrestor or MidNite Solar MNSPD-300-DC surge protector for DC nominal and 250 volts AC nominal. The power components can include one or more circuit breakers, such as a Schneider Electric 865-1070 XW Circuit Breaker. The power components can include one or more inverters, such as a Schneider Conext™ XW6848-120/240-60 Sine Wave Inverter/Charger 48V 6.8 kW Battery System, Magnum Energy™ Sine Inverter Charger, Xantrex™ Inverter/Charger, or the like. The power components can include one or more power distribution components, such as a Schneider Electric Conext™ XW+865-1015-01 Power Distribution Panel. The power components can include one or more system control panels, such as a Schneider Electric Conext™ 865-1050-01 System Control Panel (SCP) for XW+ and SW series inverters. The power components can include one or more communication or monitoring components, such as a Schneider Electric Conext™ ComBo 865-1058. The power components can include one or more generator starts, such as a Schneider Electric Conext™ XW+&amp; SW Automatic Generator Start 865-1060-01. The power components can include one or more battery monitors, such as a Schneider Electric Conext™ Battery Monitor 24/48 Volts 865-1080-01. The power components can include one or more batteries, such as a Discover 12-48-6650 6.65 KwH AES Lithium-Ion Battery. The power components can be connected to the refrigeration system  126 . The power components can be connected to the solar power system  100 . For example, one or more of the power components can be connected to the solar power system  100  or the refrigeration system  126  during an installation process of the solar power system  100 . 
     The power components disposed on transportation system  110  can include one or more power controller components  122 . The one or more power controller components  122  can include a power converter or a blocking diode. The power converter can convert energy from the power generation component to a form of energy that can be used by the refrigeration system  126 . For example, the power generation component can be a solar power system  100 . The solar power system  100  can produce varied amounts of power based on available solar radiation. The one or more power controller components  122  can help ensure that excess power is not supplied to a refrigeration system  126  or stored in a battery system  124 . In another example, the power generation component can be a solar power system  100  that generates direct current (DC) converted or transformed to (AC) with converter or invertor options for power. A refrigeration system  126  can be connected to the one or more power components  122 . The refrigeration system  126  can operate on alternating current (AC) or direct current (DC) power. The one or more power components  122  can, for example, convert DC power from the solar power system  100  to AC power for use in the refrigeration system  126 . Additionally or alternatively, the same power controller components  122  or different power components can convert power from a battery system  124  for use in a refrigeration system  126 . 
     The one or more power controller components  122  disposed on the transportation system  110  can be connected to a battery system  124 . The battery system  124  can include a battery or battery bank that can store power originating from the power generation components. The battery or batteries within a battery bank can be made of a suitable chemical component, such as lithium ion or lead acid. The battery or total battery bank can have a useful capacity of 5-100 kWh. For example, a battery can have a 10 kWh useful capacity. The battery system can have enough useful storage capacity to serve as a backup power source when the power generation component is not generating sufficient power. For example, a power generation component can be a solar power system  100  that cannot generate sufficient power when the sun is occluded or at night. The battery system  124  can have enough useful storage capacity to provide the refrigeration system  126  with sufficient power to cover a typical night period. For example, the battery system can have enough useful capacity to power the refrigeration system  126  for 12 to 24 hours when the refrigeration system  126  is operating to maintain a temperature of between −5° C. and 20° C. 
     In some examples, a display  123  may be disposed onto a portion of the solar power system  100  or transportation system  110 . The display  123  may be configured to display information relating to the solar power system  100 , such as the amount of power in or out of the battery system  124 . Additionally or alternatively, the display  123  may be configured to display the amount of power remaining in the battery system  124 . In some examples, the one or more power components can be configured to wirelessly or with wires communicate with a user device, mobile device, computer, database, the like or a combination thereof. In some examples, battery and/or system information may be stored in local or remote storage for current or future access by a user. Advantageously, remote storage of system information may allow a user to access status information of a solar power system  100  from a remote location, such as while a vehicle is parked and a driver or user is away from the vehicle. 
     In some examples, one or more power components can include an external power access (such as external power access  712  illustrated in  FIG. 1E ). An external power access can interact with other power components so as to facilitate removal and/or addition of power to the battery system  124 . Additionally or alternatively, the external power access may facilitate direct use of actively generated power from one or more solar panel packages  111 . Advantageously, the external power access may help ensure full power in the battery system even when conditions for solar power generation are not favorable. For example, the external power access may allow a user to plug the battery system in for charging to an external power source. 
     In some examples, one or more of the power components, such as the power controller components  122 , battery  124 , or other components can be attached, disposed, or secured onto one or more parts of the transportation system  110 . For example, the one or more power components may be secured within one or more weather resistant boxes that may in turn be secured onto the exterior of the transportation system  110 , such as the front, side, underside, or other portion of the transportation system  110 , such as the trailer. In some examples, the one or more power components may be secured on the interior of the transportation system  110 . In some examples, some of the one or more power components may be secured on the interior and some of the one or more power components may be secured on the exterior of the transportation system  110 . For example, a battery system  124  may be secured in a weather resistant box on the exterior of the trailer and power controller components  122  may be secured on the interior of the trailer. In some examples, the one or more power components may be secured onto different portions of an exterior of the trailer. For example, as illustrated in  FIG. 1A , a battery system  124  may be secured onto an underside of a trailer and other power components, such as power controller components  122 , may be secured onto a side of the trailer. However, other configurations are also possible. 
     The refrigeration system  126  can include some combination of refrigeration components such as a fan, evaporator, engine, compressor, and condenser. The refrigeration system  126  can help consistently maintain an approximate temperature within an interior of the trailer  121 . The refrigeration system  126  can be able to maintain temperatures within the range of −5° C. and 20° C. For example, the refrigeration system  126  can maintain a temperature of −5° C. The refrigeration system  126  can draw power from a power source in order to maintain a desired temperature within the interior of the trailer  121 . The refrigeration system  126  can require a supply voltage of between 200 and 500 volts. For example, the refrigeration system  126  can require a supply voltage of 440/460 volts. In another example, the refrigeration system  126  can require a supply voltage of 208/230 volts. The refrigeration system  126  can require a current of 30 or 100 amps. For example, the refrigeration system  126  can require a minimum current of 50 amps. The refrigeration system  126  can be able to run on a utility frequency of between 50 and 60 Hz. For example, the refrigeration system  126  can run on a utility frequency of 50 Hz. Additionally or alternatively, the refrigeration system  126  can be able to run on a direct current (DC) supply. The source of AC or DC power can be any suitable power source. For example, the solar power system  100 , a stationary solar array, or electrical grid system can provide an AC or DC supply and the refrigeration system  126  can be able to run on the power supply provided from those or other suitable sources of DC power. 
     The sun exposed surface  130  can be a surface of the truck or trailer capable of being exposed to sunlight. For example, the sun exposed surface  130  can be a surface of the truck  120  or trailer  121  that is not covered by shadow or another component of the truck or trailer  121 . The sun exposed surface  130  can include a roof or side walls of the truck  120  or trailer  121 . The sun exposed surface  130  can optionally include an insulated material. The sun exposed surface  130  can include a metallic outer surface. 
     II. Example System Configuration 
       FIGS. 1B-1, 1B-2, 1C-1, and 1C-2  illustrate top and side views of embodiments of a solar power system  100  that can be disposed on a sun-exposed surface  130  of a transportation system  110 . The solar power system  100  can include one or more solar packages  111 . For example, the solar power system  100  can include two sets of solar packages  111 . In the example illustrated in  FIG. 1B-1 , the solar power system  100  includes two sets of twelve solar packages  111 . In the example illustrated in  FIG. 1B-2 , the solar power system  100  includes six solar packages  111 . However, any number of configurations are also possible, such as a single solar panel package  111 , or one, two, three, or more sets of one or more solar packages  111 , or some other suitable configuration. 
     The solar power system  100  that can cover any percentage of a sun-exposed surface  130 . For example, the solar power system  100  can cover 20%, 45%, or 90% of the roof of a truck trailer. The coverage area of the surface can be related to a desired power output of the solar power system  100 . For example, a refrigeration system coupled to a truck trailer can require 4 kW over the course of an hour and the solar power system  100  can generate 5 kW per hour when covering 100% of the roof of the truck trailer. Thus, the solar power system  100  that can cover 80% of the roof of the truck trailer in order to generate only the amount of needed power and reduce weight. 
     Additionally or alternatively, the solar power system  100  can be provided to other surfaces. For example, the solar power system  100  can be provided to an extension of the sun-exposed surface  130  or the solar power system  100  itself can extend beyond the sun-exposed surface  130 . The solar power system  100  can be provided to other parts of truck  120  or trailer  121 . For example, the solar power system  100  can be provided to the cab area  132  of the truck  120 . 
     There can be more than one solar power system  100  in the truck trailer power system  100 . For example, there can be a solar power system  100  provided to a sun-exposed surface  130  that can provide power to a trailer  121  and there can be a solar power system  100  provided to a surface of a cab area  132  of the truck  120  to provide power to the cab area  132 . Additionally or alternatively, a solar power system  100  can be provided to other areas of the truck  120 . 
     The solar power system  100  can be substantially flat or substantially parallel to a sun-exposed surface  130  or other surface upon which the solar power system  100  is disposed. The solar panel packages  111  in the solar power system  100  can be between ¼″ and 6″ thick. For example, the solar power system  100  can be ⅛″, ¼″, ½″ or ¾″ thick. Advantageously, ¼″ thickness provides a more aerodynamic posture. A thicker solar power system  100  can include further layers of support and protection from damage that cannot be possible with a thinner solar power system  100 . For example, as will be discussed below, a solar panel package  111  within a solar power system  100  can include a support layer with shock absorbing foam. The foam can add additional height to the configuration. For example, the foam can be 1″ thick. Thus, the solar power system  100  may, for example, be 1¼″ thick when 1″ is added to the solar panel package  111 . A maximum height of the solar power system  100  can be dictated by height of the transportation system  110 . For example, a transportation system  110  can be some combination of a truck  120  and trailer  121 . The total truck  120  and trailer  121  height can be capped by regulations at a maximum height of 13′6″ or 15′. The solar packages  111  in the solar power system  100  can be any suitable dimension. A minimum dimension of the solar packages  111  can be dictated by power needs. For example, in general, the larger a solar cell (which can be contained within a solar panel package  111 ), the more photon conversion area. Advantageously, with increased photon conversion area, power generation will generally also increase. A maximum size of the solar packages  111  can be dictated by the size of the surface upon which they are disposed. For example, a sun-exposed surface  130  can be 102″ wide, so the solar packages  111  can be up to 102″ wide. In another example, a sun-exposed surface  130  can be 40′ long, so the solar packages  111  can be up to 40′ long. In another example, a sun-exposed surface  130  can be 53′ long, so the solar packages  111  can be up to 53′ long. The dimensions of a solar panel package  111  can be less than the maximum size of the surface upon which it is disposed. For example, a solar panel package  111  can be 50″ long. Advantageously, making the dimensions of a solar panel package  111  smaller than the full dimensions of a sun-exposed surface  130  can ease repair costs and other considerations. For example, if a solar power system  100  includes a single solar panel package  111  that is the full dimensions of a sun-exposed surface  130 , then even a small area of damage would require repair of the entire solar panel package  111 . If a solar power system  100  includes twenty four solar panel packages  111 , then a small area of damage can be limited to a limited number of solar panel packages  111  and only that limited number would require repair. Thus, costs can be lowered for repair with dimensions less than the full size of the sun-exposed surface  130 . 
     In some examples, one or more portions of the solar power system  100  can have a weight per square foot less than 1 pounds, 0.6 pounds, 0.5 pounds, or any other weight per square foot. The weight per square foot may be approximately the same for one or more different sizes of the solar power system  100 . For example, an embodiment of a solar panel package of a solar power system  100  of a size of about 14 inches by 23 inches (or about 36 cm by about 58 cm) may have a total weight of about 1.2 pounds (or about 0.54 kg) and/or a weight (in lbs) per square foot of about 0.537. In another example, an embodiment of a solar panel package of a solar power system  100  of a size of about 14 inches by 23 inches (or about 36 cm by about 58 cm) may have a total weight of about 1.25 pounds (or about 0.57 kg) and/or a weight (in lbs) per square foot of about 0.559. In another example, an embodiment of a solar panel package of a solar power system  100  of a size of about 20 inches by 29 inches (or about 51 cm by about 77 cm) may have a total weight of about 2.2 pounds (or about 1 kg) and/or a weight (in lbs) per square foot of about 0.546. In another example, an embodiment of a solar power system  100  of a size of about 20 inches by 29 inches (or about 51 cm by about 77 cm) may have a total weight of about 2.25 pounds (or about 1.02 kg) and/or a weight (in lbs) per square foot of about 0.559. 
     In some examples, one or more solar panel packages  111  may be configured to be disposed onto the surface of the trailer  130 , such as illustrated in  FIG. 1C-1 . In some examples, one or more solar panel packages  111  may be configured to be disposed onto one or more movable components  150 , such as illustrated in  FIG. 1C-2 . It is of note that while  FIG. 1C-2  illustrates a single movable component, a system may include a plurality of movable components  150 . A movable component  150  can include a hinged or otherwise movable, foldable, or collapsible panel configured to lie against a portion of the transportation system  110 , such as the trailer  130 , when not in use. The movable component  150  may be supported by one or more support structures, such as one or more pistons  152  or other structural components capable of maintaining the weight and location of the movable component  150  during use, such as one or more support bars  154 . In some examples, the movable component  150  may be raised in order to place one or more solar panel packages  111  that may be disposed on or a part of the movable component  150 , such as the one or more support bars  154 , so as to capture sunlight in one or more solar cells in the solar panel package  111 . For example, the one or more movable components  150  may be configured to raise one or more solar panel packages  111  that may disposed on or as a part of the movable component  150  to be approximately flush and/or approximately parallel to one or more solar panel packages  111  disposed onto a surface of the trailer  130 . It is of note that while the example shown in  FIG. 1C-2  illustrates a placement of the movable component  150  as parallel to the ground and/or the top of the trailer  130 , an angle θ of the movable component  150  and/or solar panel packages  111  disposed on or part of the movable component  150  may be at any suitable angle, such as less than or greater than 90 degrees from a side of the transportation system  110 . In some examples, the angle θ of the movable component  150  may be 20 degrees, 35 degrees, 50 degrees, 110 degrees, 160 degrees or another angle in relation to the side of the trailer. In some examples, the angle of the movable component  150  may be determined based on desired clearance at the sides of the trailer. For example, the movable component  150  may be angled to raise at least a portion of the movable component  150  and/or solar panel package disposed on or a part of the movable component  150  above a height of the trailer or vehicle so that the trailer or vehicle may be parked in a location with less clearance around the sides of the trailer. 
     In some examples, one or more movable components  150  can be disposed onto one or more sides of the transportation system  110 . The one or more movable components  150  may be disposed during vehicle or trailer manufacture or as part of retrofitting a vehicle or trailer. For example, a transportation system  110  may have a side portion corresponding to a driver side  112 A, a side portion corresponding to a passenger side  112 B, a front portion corresponding to a front of the trailer  113 A and a back portion corresponding to a back of the trailer  113 B. A movable component  150  may be disposed onto one or more of the two side portions, front portion, or back portion. Advantageously, the movable component  150  may facilitate use of a greater number of solar cells and/or allow for a greater amount of power generation based on user need. In some examples, a movable component  150  may be disposed onto a top portion of the trailer  130  in order to facilitate movement of one or more solar panel packages  111  for better placement of the one or more solar panel packages  111  for capture of sunlight and production of power. For example, the one or more movable components  150  may allow for the one or more solar panel packages  111  to face south in appropriate areas to capture the more direct south facing sun. In other examples, the one or movable components  150  may move dynamically or be customizable so as to facilitate capture of sunlight based on time of day, parking direction of the transportation system  110 , or other parameter related to the capture of sunlight by the solar power system  100 . In some instances, the angle of the movable component with respect to a surface of the trailer, such as a surface of a side portion corresponding to a driver side  112 A or passenger side  112 B of a trailer, may be automatically determined based on location data received from GPS (global positioning service) device on a transportation system (or a mobile device) and time of day. 
     The one or more movable components  150  and/or solar panel packages  111  can be of any size or shape according to user need or desire. For example, a movable component  150  disposed onto the side of a trailer  130  may be approximately the size and shape of the side of the trailer  130 . In other examples, the movable component  150  may be smaller than the size and shape of the side of the trailer  130 . In other examples, the movable component  150  may be a different size and/or shape than the side of the trailer. In some examples, the movable component  150  may be foldable. In some examples, the movable component may be a static or dynamic size and/or shape. 
     In some examples, the one or more movable components  150  can include one or more electrical connections or components. For example, the one or more movable components  150  may include one or more controllers, actuators, solar panel packages  111 , or other components configured to control the movement or function of portions of the movable component  150 , such as a solar panel package  111 . The one or more electrical connections or components may be electrically connected to other electrical components in the solar power system  100 , such as the one or more power controller components  122  or battery system  124 . In some examples, one or more support or control systems for moving the movable component  150  may be electrically connected to the battery  124  such that the battery may provide power to the one or more support or control systems. In other examples, the one or more electrical components of the movable component(s)  150  can include one or more transmitters and/or receivers capable of transmitting or receiving signals related to controlling the movement and/or operation of the one or more movable components  150 . 
     In some examples, the solar power system  100  may include one or more securing components  156  configured to secure the one or more movable component(s) and/or solar panel package(s) to a side of the trailer or other object or surface upon which the movable component(s) is attached. For example, a securing component  156  can include a clasp, fastener, clip, pin, hook, buckle, lock, the like or combination thereof. Advantageously, a securing component may allow the system to securely transport the trailer or other object and help prevent damage to the solar panel system as a result of transport and/or impact damage due to transport. 
     In some examples, the solar power system  100  may include one or more support components  154  configured to secure at least a portion of the movable component(s)  150  and/or solar panel package(s)  111  to the vehicle or trailer. For example, the support portion  154  may include one or more hinges. The one or more hinges can be configured to secure a top edge of the movable component(s)  150  and/or solar panel package(s)  111  to a top edge or other portion of the vehicle or trailer. 
     III. Example Implementation of a Solar Panel System 
       FIGS. 1D-1F  illustrate views of an example implementation of an embodiment of the solar panel systems and methods described herein.  FIG. 1D  illustrates external views of an example carry on trailer implementation of an embodiment of a solar power system.  FIG. 1E  illustrates views of an example electrical setup that may be associated with an example implementation.  FIG. 1F  illustrates internal views of an example carry on trailer implementation of an embodiment of a solar power system. 
     As illustrated in  FIG. 1D , a solar panel system may be disposed onto a carry on trailer. In some examples, a solar panel system  100  can be disposed onto a top portion  702  of the carry on trailer  700  such that the solar panel system  100  is sun exposed. However, the solar panel system  100  can be disposed on any suitable surface of the trailer  700 . While a carry on trailer is illustrated, it will be appreciated that the solar panel system  100  may be disposed on other types of vehicles, trailers, or the like. 
     In some examples, a carry on trailer can be outfitted with one or more electronic components that are configured to interact with the solar panel system  100 . The one or more electrical components may be disposed onto a portion of the trailer, such as on an interior or exterior of a front portion  704 . In some examples, electronic components can include one or more power components such as described above.  FIG. 1E  illustrates views of example electronic components  711  that may be disposed on or within a trailer  700 . For example, as illustrated in  FIG. 1E , power components can include a power inverter  710 , charge controller  714 , external power supply or plug  712 , power connection  716 , and/or battery  718 . Inset  710 A illustrates an example configuration of an example power inverter that may be configured to interact with the solar panel system  100 . It is of note that the electronic components  711  may be similarly or otherwise suitably configured in another transportation system  110  or other application of a solar power system  100 . 
     In some examples, a power connection  716  can include a connection of the one or more electronic components  711  to one or more solar panel packages  111 . In the illustrated example in  FIG. 1E , a power connection  716  is align along the front peak of the interior portion of the trailer  700 . The power connection  716  may include one or more cables configured to lie along a wall, corner, or other portion of the trailer  700  and connected to one or more solar panel packages  111  on the exterior of the trailer  700 . In some examples, the power connection  716  may be fed through a feed through connector from the interior to the exterior of the trailer  700 . It is of note that a power connection  716  to/from a solar panel package  111  to/from one or more electronic components in another transportation system  110  or other application of a solar power system  100  may be similarly or otherwise suitably configured. 
       FIG. 1F  illustrates views of an interior  701  of the trailer  700 . In the illustrated example, one or more electronic components  711  can be disposed onto a portion of the interior of the trailer  700 . For example, one or more electronic components  710  may be mounted, attached, or otherwise disposed onto an interior wall  714  of the trailer  700 . The one or more electronic components may be electrically connected to a solar power system disposed on another portion of the trailer  700 , such as the top portion  702  of the trailer  700 . In some examples, the one or more electronic components may be concealed within the trailer behind, for example, a wall or other covering. Advantageously the wall or other covering may help prevent cargo from interacting with the one or more electronic components  711 .  FIG. 1F  illustrates an example stud wall  716  that may be part of an example electronic components covering. In some examples, the electronic components covering may include one or more access portions configured to allow a user to access the one or more electronic components. In the example illustrated in  FIG. 1F , the stud wall  716  can include an example doorway  718  to facilitate user access to the one or more electronic components  710 . 
     In some examples, one or more of the electronic components may be disposed on the exterior of the trailer  700 . One or more coverings, such as a weather resistant box may be disposed over the one or more electronic components in order to protect the one or more electronic components from road and/or weather wear. 
     IV. Solar Power System 
       FIG. 2A  illustrates a block diagram of an example solar power system  100 . For example, the solar power system  100  can include a number of layers disposed onto a surface  216 . As illustrated, the solar power system  100  can include some combination of an adhesive layer  214 , a solar panel package  111 , and an encapsulating layer  210 . 
     The surface  216  on which the solar panel package  111  can be disposed can be composed of any suitable material. For example, the surface  216  can be a container or sun-exposed surface  130  (as shown in  FIGS. 1A-1C ). The surface  216  can be composed of a metal, such as aluminum. The surface  216  can include other types of surfaces or substrates that can cover a roof surface of a transportation system  110 . For example, surface  216  can be a protective coating for the surface  216 , such as a plastic resin. In another example, the surface  216  can be a flexible material, such as fabric. 
     The encapsulating layer  210  can be a layer or multiple layers that can help prevent damage to solar cells in the solar panel package  111  that can occur due to impacts from debris or other source of damage during transport of goods being cooled by the solar power system. The encapsulating layer  210  can allow light to transmit through the encapsulating layer  210  to the solar panel package  111 . For example, the encapsulating layer  210  can be composed of a transparent plastic material. The encapsulating layer  210  can be composed of at least one protective film. For example, the encapsulating layer  210  can be composed of a laminate film or multiple laminate films. The encapsulating layer  210  can be applied through a heat application process. For example, the encapsulating layer  210  can be composed of a laminate film and the layer can be applied by melting or partially melting the film onto the solar panel package  111 . 
     Additionally or alternatively, the encapsulating layer  210  can include an ink layer. The ink layer can be disposed onto another portion of the encapsulating layer  210  or onto the solar panel package  111 . For example, the encapsulating layer  210  can include a laminate film. The ink layer can be disposed on top of the solar cells to obscure the string lines on the solar panel. In another example, the ink layer can be disposed directly on top of the solar panel package  111 . The ink layer can be disposed onto the entirety or a portion of the solar power system  100 . For example, the solar power system  100  can include a solar panel package  111 . The solar panel package  111  can include a solar cell layer  218  (as shown in  FIGS. 3A and 3B ). The solar cell layer  218  can include electrical leads or connections. The electrical leads or connections can form a pattern on top of the solar cell layer  218 . The ink layer can be one or more layers of ink disposed onto the electrical leads such that the electrical leads are less immediately visible to the unaided human eye. Thus, the ink layer may increase the aesthetics of the solar power system  100 . 
     The solar panel package  111  can be a system consisting of a layer of materials designed to capture photon energy for conversion into electricity. As will be discussed below, the solar panel package  111  can include some combination of support materials, conductive materials, and solar cells. 
     The adhesive layer  214  can be one or more layers of material configured to adhere the solar panel package  111  to the surface  216 . For example, the surface  216  can be an aluminum surface of a trailer and the adhesive layer can include an adhesive bond or adhere to the aluminum surface. The adhesive layer  214  can include a resin, such as an epoxy or polyester resin. The adhesive layer  214  can further include another material that can reinforce or provide support to the solar power system  100 . The adhesive layer can include more than one layer of adhesive material. For example, the adhesive layer  214  can include two or more layers of adhesive. There can be more than one adhesive layer  214  in the system  100 . The adhesive layer can be between any two or more layers of the system  100 . 
     The solar power system  100  that can adhere to a surface with or without the need for further structural support, such as a frame or other support attached using mechanical means to the truck sun-exposed surface  130 . The solar power system  100  can be permanently applied to a surface  216 . For example, as will be described below, the solar power system  100  can include an adhesive layer  214  that can bond with the sun-exposed surface  130 . Additionally or alternatively, the solar power system  100  can be attached to the surface  216  by adhesive materials such as tape, epoxy resins, or other combinations of chemicals to create a bond between the surface  216  and the solar power system  100 . Additionally or alternatively, the solar power system  100  can be removably applied to a surface  216 . For example, the solar power system  100  can be applied to an intermediary material or surface other than the surface  216 . The intermediary surface can couple to the surface  216  through mechanical or other means, such as with an adhesive or through adhesive bonding. 
       FIG. 2B  illustrates an example solar power system application process  300 . The solar power system  100  can be applied with a frame or without a frame or similar structure. The process  300  can involve applying an adhesive layer  214  to a surface  216  in one or multiple steps  310 . The process can involve disposing the solar panel package  111  to the adhesive layer  214  in a step  312 . The process can further involve applying an encapsulating layer  210  in a step  314 . 
     At a step  310 , the adhesive layer  214  can be applied to a surface  216 . The adhesive layer  214  can secure the one or more solar panel packages  111 . For example, the adhesive layer  214  can be a bonding adhesive that can bond to an aluminum surface of the surface  216 , such as 3M™ Panel Bonding Adhesive or Valvoline™ Pliogrip two part adhesive. In another example, the adhesive layer  214  can include adhesive sealing tape, such as 3M™ Extreme Sealing Tape. The adhesive layer  214  can be applied across the entirety of the area of the surface  216  to which the solar power system  100  can be disposed or a portion of the area of the surface  216  to which the solar power system  100  can be applied. For example, the adhesive layer  214  can be applied on the edges of the solar power system  100  and/or the adhesive layer  214  can be applied in a pattern on the surface  216 . 
     At a step  312 , at least one solar panel package  111  can be disposed onto the adhesive layer  214 . The solar package(s)  111  can be disposed in any suitable configuration. For example, as illustrated in  FIGS. 1A-1C , one or more solar packages  111  can be disposed on a driver side  112 A of a truck trailer or container and one or more solar packages  111  can be disposed on a passenger side  112 B of a truck trailer or container. 
     At a step  314 , a encapsulating layer  210  can be applied to the solar packages  111 . The encapsulating layer  210  can be a transparent material that can allow light to pass into the solar package. The encapsulating layer  210  can protect the solar power system  100  in whole or in part from excess contact or collision damage that can occur during transport of the trailer or container, from excess moisture, or other potential sources of damage to the solar power system  100 . The encapsulating layer  210  can be applied by molding, melting, or partially melting a material over the one or more solar packages  111 . The encapsulating layer  210  can be applied over the entirety of the solar power system  100  or part of the solar power system  100 . The encapsulating layer  210  can be applied to an area larger than the one or more solar panel packages  111  in the solar power system  100 . For example, the one or more solar panel packages  111  in the solar power system  100  can partly cover the roof area of a truck trailer or container. The encapsulating layer  210  can cover the one or more solar panel packages  111  and cover the roof area of the truck trailer or container that the one or more solar panel packages  111  do not cover. 
     While specific layers are described herein, other layers can be applied in order to provide the solar power system with further structure and support during transport of a trailer or container upon which the layers are coupled or disposed. While individual layers can be described, each individual layer can appear multiple times in a suitable order as part of a solar panel package  111  disposed on surface  216 . Each layer can include a single layer or include multiple layers within it. While an order of layers can be described, other orders of layers can be applied. 
     V. Solar Panel Package 
       FIGS. 3A-3B  show block diagrams of example solar packages  111  that can be part of a solar power system  100 . For example, a solar panel package  111  can include some combination of a support portion  222  (which can include reinforcement  304  and/or a shock absorption layer  306 ), a reinforcement material  220 , and a solar cell layer  218 . Each portion can appear a single time or multiple times in a suitable order. Each layer or portion can include a single layer of material or include multiple layers of material. Some configurations can include fewer combinations of portions or layers and some configurations can include more combinations of layers. For example, the solar power system  100  can include internal layers of composite materials such as: fiberglass, extruded chemical foams, honeycomb material, balsa wood, core cell or other forms of structural foam, carbon fiber, carbon nanotubes or other forms of carbon structures. 
     Portions of the solar panel package can be configured to be any share or size. For example, the support portion  222  can be configured to be of a similar size to a portion of the surface on which the solar panel package may be disposed. In other examples, the support portion  222  can be smaller or of a different shape than the available surface on which the solar panel package may be disposed.  FIG. 4  illustrates an example support portion  800  that may also include a reinforcement material  220  having a similar size to a top portion of a carry on trailer (such as the trailer  700  illustrated in  FIGS. 1D-1F ). In some examples, one or more other components of the solar panel package may be disposed onto the support portion  800 . 
     The reinforcement  304  can include a sheet of supportive material. For example, the reinforcement  304  can be a flat sheet of material that is produced through a continuous molding process, such as pultrusion. The reinforcement  304  can include a reinforcing material, such as a fiberglass roving, mat, or cloth that is impregnated with a resin. The fiberglass material can be an E-glass epoxy composite material or other type of fiberglass material, such as S-Glass epoxy composite. The composite materials can be bonded or encapsulated with resins, pre-impregnated epoxy resins or other chemical materials. The reinforcement  304  can include multiple layers of reinforcement material. For example, the reinforcement  304  can include layers of fiberglass roving and fiberglass cloth to provide extra support. 
     The shock absorption layer  306  can be one or more layers that can help absorb some vertical or other shocks and/or vibration that can occur during transport of the solar power system  100 . For example, the shock absorption layer  306  can include an energy absorbing material, such as a polyethylene, polystyrene, polypropylene, polyurethane, rubber, or other suitable material. For example, the shock absorption layer  218  can be composed of a polyethylene foam material, such as PET foam core. Additionally or alternatively, the energy absorbing material can be a foam structure or other suitable energy absorbing structure, such as a honeycomb structure. In another example, the shock absorption layer  306  can be composed of a material shaped into a geometric configuration within the layer that can allow the layer to deform under force. For example, the geometric configuration can include hexagonal-shaped cells or other suitable structure. The geometric cells can be a single size or multiple sizes and a single configuration or multiple configurations. The shock absorption layer  306  can be composed of more than one shock absorption material of one or more types or orientations. For example, the shock absorption layer  306  can be composed of a PET foam core and a honeycomb structural material. The shock absorption layer  306  can include materials that can help absorb vibrations and/or shocks in both vertical and horizontal directions. 
     There can be more than one shock absorption layer  306  in the solar panel package  111 . For example, the one or more solar panel packages  111  can include a shock absorption layer  306  between the surface  216  and the reinforcement  304 . There can be more than one type of shock absorption layer in the solar panel package  111 . For example, the solar panel package  111  can include two shock absorption layers. Multiple shock absorption layers can be composed of the same type or different types of shock absorption material. For example, there can be two or more shock absorption layers capable of absorbing some of the vibrations and/or shocks in two different directions relative. 
     Additionally or alternatively, the shock absorption layer  306  and reinforcement  304  can be part of a support portion  222 , as illustrated in  FIG. 3A . The support portion  222  can include some combination of shock absorption layers  306  and reinforcement  304 . The support portion  222  can have supportive properties. For example, the support portion  222  can be composed of a single material that has shock absorption and/or supportive properties. 
     In some examples, a solar panel package  111  can include a reinforcement material  220 . The reinforcement material  220  can include a layer or multiple layers of material capable of providing reinforcement to the solar panel package  111 . Advantageously, the reinforcement material  220  can also provide rigidity to the system. The reinforcement material  220  can be composed of a material capable of maintaining rigidity when impregnated with resin and conducting electricity. For example, the reinforcement material  220  can be a conductive carbon fiber layer. The carbon fiber layer can be a carbon fiber reinforced carbon layer, a coated carbon fiber (such as through chemical vapor deposition or CVD), or other suitable alternative. 
     In some examples, the reinforcement material  220  can include a material capable of conducting electricity. For example, the reinforcement material  220  can be carbon fiber impregnated with resin. The resin can be an epoxy resin or other suitable resin. The carbon fiber can be a carbon twill or other suitable weave. Additionally or alternatively, the reinforcement material  220  can be composed of a conductive material, such as carbon, silver, or other suitable conductive material. The reinforcement material  220  can be placed below the solar cell  218 . Advantageously, the conductive material can increase the efficiency of the solar power system  100  by increasing photon capture of the solar cell layer  218 . 
     The solar cell layer  218  can be a layer or multiple layers that can be composed of a photovoltaic material or materials. For example, the solar cell layer  218  can include a solar cell or set of solar cells, such as DG 884 W Solar Power Panels. The solar cells can be composed of a suitable semiconductor material, such as crystalline silicone. The solar cells can be wafer-based cells, thin film cells, or other solar cell type. For example, a solar cell layer  218  can be composed of thin film solar cell(s) that are lightweight. The solar cell layer  218  can have an efficiency sufficient to supplement a power supply or act as the sole power supply for a refrigerated trailer or container when in context of the solar power system  100 . For example, the solar panel package  111  may be able to convert solar energy at an efficiency above 5% of the solar cell “nameplate” efficiency. In another example, the solar cell layer  218  may be able to convert solar energy with an efficiency of approximately 15% of the solar cell “nameplate” efficiency, depending on the conductive materials used. 
     While specific layers are described herein, other layers can be applied in order to provide the solar cell system with further structure and support during transport of a trailer or container upon which the layers are coupled or disposed. While individual layers can be described, each individual layer can appear multiple times in a suitable order as part of a solar panel package  111  disposed on a surface  216 . Each layer can include a single layer or include multiple layers within it. While an order of layers can be described, other orders of layers can be applied. For example, as shown in  FIG. 3B , a solar panel package  111  can include more than one layer of reinforcement material  220 . In another example, as shown in  FIG. 3B , a support portion  222  can be entirely or in part replaced by a reinforcement  304 . 
       FIG. 5A  illustrates an example solar panel package  400 . For example, the solar panel package  400  can include a plurality of solar cells  410 . The plurality of solar cells  410  may be disposed on top of a structure  420 . The structure  420  can include a carbon fiber layer (such as the reinforcement material  220  referenced above) and a support layer (such as the shock absorption layer  306  or reinforcement  304 ). The solar panel package  400  can include electrical connections or leads  430  for connecting the solar panel package to other electrical systems. The solar panel package  400  can be disposed on a sun exposed surface  130 . The solar panel package  400  can be encapsulated by an encapsulating layer  210 . The encapsulating layer  210  can include an ink layer that may cover the electrical leads  430  or other electrical components with dark ink so that the solar cells  410  are less apparent to the naked eye. 
       FIG. 5B  illustrate example variants of an example solar panel package. For example, a solar panel package can include a black variant  450 , a white variant  452 , and a grey variant  454 . However, other color variants are also possible. The black variant  450  includes a carbon fiber infused variant of the solar panel package that lends the black color to the solar panel package. The white variant  452  is an example of a colored variant of the solar panel package in which an epoxy used in preparation of one of more layers of the solar panel package is pre-impregnated with a white color during manufacturing. It is of note that while a white variant  452  is illustrated, other colors are also possible. A grey color variant  454  is an example of an uncolored variant of the solar panel package. Advantageously, a color variant may allow a solar panel package  111  to be color matched or partially color matched to a surface on which the solar panel package  111  is disposed. For example, a white color variant may be applied to a white trailer. Advantageously, this may provide a more aesthetically pleasing and less visually invasive solar power system. Additionally, a brighter color variant may facilitate an improved efficiency of power generation over a darker solar panel package, such as illustrated in Table 1 below and  FIG. 6 . 
       FIG. 6  illustrate example test results  460 ,  462 , and  464  of a black variant  450 , white variant  452 , and grey variant  454  respectively. Table 1 illustrates example parameters associated with the test results illustrated in  FIG. 6 . Italicized values in parenthesis correspond to example values associated with solar cells that may be included in respective solar packages.

     VI. Terminology 
     Many other variations than those described herein will be apparent from this disclosure. For example, depending on the embodiment, certain acts, events, or functions of any of the algorithms described herein can be performed in a different sequence, can be added, merged, or left out all together (e.g., not all described acts or events are necessary for the practice of the algorithms). Moreover, in certain embodiments, acts or events can be performed concurrently, e.g., through multi-threaded processing, interrupt processing, or multiple processors or processor cores or on other parallel architectures, rather than sequentially. In addition, different tasks or processes can be performed by different machines or computing systems that can function together. 
     The various illustrative logical blocks, modules, and algorithm steps described in connection with the embodiments disclosed herein can be implemented as electronic hardware, computer software, or combinations of both. To clearly illustrate this interchangeability of hardware and software, various illustrative components, blocks, modules, and steps have been described above generally in terms of their functionality. Whether such functionality is implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system. The described functionality can be implemented in varying ways for each particular application, but such implementation decisions should not be interpreted as causing a departure from the scope of the disclosure. 
     The various illustrative logical blocks and modules described in connection with the embodiments disclosed herein can be implemented or performed by a machine, such as a general purpose processor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. A general purpose processor can be a microprocessor, but in the alternative, the processor can be a controller, microcontroller, or state machine, combinations of the same, or the like. A processor can also be implemented as a combination of computing devices, e.g., a combination of a DSP and a microprocessor, a plurality of microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration. Although described herein primarily with respect to digital technology, a processor can also include primarily analog components. For example, any of the signal processing algorithms described herein can be implemented in analog circuitry. A computing environment can include any type of computer system, including, but not limited to, a computer system based on a microprocessor, a mainframe computer, a digital signal processor, a portable computing device, a personal organizer, a device controller, and a computational engine within an appliance, to name a few. 
     The steps of a method, process, or algorithm described in connection with the embodiments disclosed herein can be embodied directly in hardware, in a software module executed by a processor, or in a combination of the two. A software module can reside in RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, hard disk, a removable disk, a CD-ROM, or any other form of non-transitory computer-readable storage medium, media, or physical computer storage known in the art. An exemplary storage medium can be coupled to the processor such that the processor can read information from, and write information to, the storage medium. In the alternative, the storage medium can be integral to the processor. The processor and the storage medium can reside in an ASIC. The ASIC can reside in a user terminal. In the alternative, the processor and the storage medium can reside as discrete components in a user terminal. 
     Conditional language used herein, such as, among others, “can,” “might,” “may,” “e.g.,” and the like, unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain embodiments include, while other embodiments do not include, certain features, elements or states. Thus, such conditional language is not generally intended to imply that features, elements or states are in any way required for one or more embodiments or that one or more embodiments necessarily include logic for deciding, with or without author input or prompting, whether these features, elements or states are included or are to be performed in any particular embodiment. The terms “comprising,” “including,” “having,” and the like are synonymous and are used inclusively, in an open-ended fashion, and do not exclude additional elements, features, acts, operations, and so forth. Also, the term “or” is used in its inclusive sense (and not in its exclusive sense) so that when used, for example, to connect a list of elements, the term “or” means one, some, or all of the elements in the list. 
     Disjunctive language such as the phrase “at least one of X, Y, or Z,” unless specifically stated otherwise, is otherwise understood with the context as used in general to present that an item, term, etc., can be either X, Y, or Z, or any combination thereof (e.g., X, Y, or Z). Thus, such disjunctive language is not generally intended to, and should not, imply that certain embodiments require at least one of X, at least one of Y, or at least one of Z to each be present. 
     Unless otherwise explicitly stated, articles such as “a” or “an” should generally be interpreted to include one or more described items. Accordingly, phrases such as “a device configured to” are intended to include one or more recited devices. Such one or more recited devices can also be collectively configured to carry out the stated recitations. For example, “a processor configured to carry out recitations A, B and C” can include a first processor configured to carry out recitation A working in conjunction with a second processor configured to carry out recitations B and C. 
     While the above detailed description has shown, described, and pointed out novel features as applied to various embodiments, it will be understood that various omissions, substitutions, and changes in the form and details of the devices or algorithms illustrated can be made without departing from the spirit of the disclosure. As will be recognized, certain embodiments described herein can be embodied within a form that does not provide all of the features and benefits set forth herein, as some features can be used or practiced separately from others. It should be emphasized that many variations and modifications can be made to the above-described embodiments, the elements of which are to be understood as being among other acceptable examples. All such modifications and variations are intended to be included herein within the scope of this disclosure and protected by the following claims.
