The present invention is directed to photovoltaic systems. More particularly, the invention provides systems and methods for mounting photovoltaic modules. Merely by way of example, the invention has been applied to the mounting of photovoltaic modules onto concrete rails. But it would be recognized that the invention has a much broader range of applicability.
Photovoltaics convert sunlight into electricity, providing a desirable source of clean energy. A conventional photovoltaic (PV) module includes a semiconductor layer divided up into a series of interconnected light-sensitive cells. In order to increase the amount of sun light that is converted into electricity, a photovoltaic module needs to be correctly oriented relative to the sun. For example, the orientation will vary depending upon the location of the PV module (e.g., its latitude and longitude). In another example, a mounting system is utilized to provide the orientation of the PV module.
Hence, it is highly desirable to improve techniques for the mounting of PV modules.

5. DETAILED DESCRIPTION OF THE INVENTION
The present invention is directed to photovoltaic systems. More particularly, the invention provides systems and methods for mounting photovoltaic modules. Merely by way of example, the invention has been applied to the mounting of photovoltaic modules onto concrete rails. But it would be recognized that the invention has a much broader range of applicability.
In order to orient a photovoltaic (PV) module (e.g., a photovoltaic panel, a solar module, a solar panel, a glass module, a glass panel, a glass-to-glass module, and/or a glass-to-glass panel) relative to the sun, a mounting system is required. For example, the mounting system requires a mechanical substrate to which the photovoltaic module is mounted. In other example, the mechanical substrate includes a mechanical frame. In yet another example, the mechanical substrate includes a modular concrete rail.
FIG. 1 is a simplified diagram showing a modular rail upon which a PV module may be mounted. This diagram is merely an example, which should not unduly limit the scope of the claims. One of ordinary skill in the art would recognize many variations, alternatives, and modifications. As shown in FIG. 1, the modular rail 100 includes one or more mounting surfaces 110. For example, the one or more mounting surfaces 110 serve as the mechanical substrate for the mounting of one or more PV modules. In another example, the mounting surfaces 110 are substantially coplanar.
FIG. 2 is a simplified diagram showing a PV module mounted on the modular rail 100. This diagram is merely an example, which should not unduly limit the scope of the claims. One of ordinary skill in the art would recognize many variations, alternatives, and modifications. In one embodiment, a PV module 200 is mounted to the one or more mounting surfaces 110 by using at least one or more mechanical mounts. For example, the PV module 200 is a glass-to-glass module. In another embodiment, the one or more mounting surfaces 110 of the modular rail 100 are implemented with a tilt angle. For example, the tilt angle varies depending upon the geographic location (e.g. latitude or orientation) of the PV module so that the affixed PV module 200 is oriented for optimal energy capture from the light source (e.g., the sun).
The use of the one or more mounting surfaces 100 provides certain advantages over conventional technology for the mounting of PV modules. In one embodiment, the PV modules 200 are fixed along their entire length to the one or more mounting surfaces 110 using one or more mechanical mounts. In another embodiment, the PV modules 200 do not have to be as strong as required by certain conventional technology. For example, the mechanical mounting along the one or more surfaces 110 provides a shorter span between the contact points of the PV modules 200 and the one or more mounting surfaces 110; therefore, the PV modules 200 are exposed to less mechanical stress due to wind loads than the PV modules mounted using conventional edge-mounted brackets. In another example, the PV modules 200 is made of thinner material than the conventional edge-mounted PV modules; therefore, the PV modules 200 is manufactured and transported at lower cost due to their lighter weight.
In yet another embodiment, the PV modules 200 benefit from the “heat sink” effect due to the proximity of the PV modules 200 to the modular rails 110. For example, the PV modules 200 can stay slightly cooler than conventional modules and can operate more efficiently (e.g., due to the negative temperature coefficient). In yet another embodiment, the use of mechanical mounts between the PV modules 200 and the one or more surfaces 110 can provide the PV modules 200 with additional air cooling that can significantly reduce negative effects caused by the “heat sink” effect of the modular rails 100.
FIG. 3 is a simplified diagram showing another modular rail upon which a PV module may be mounted. FIG. 4 is a simplified diagram showing a PV module mounted on the another modular rail. These diagrams are merely examples, which should not unduly limit the scope of the claims. One of ordinary skill in the art would recognize many variations, alternatives, and modifications. As shown in FIGS. 3 and 4, a modular rail 300 includes only a single mounting surface 310 for the PV module 200 according to one embodiment.
In one example, the modular rail 100 and/or the modular rail 300 is constructed from concrete. In yet another example, the modular rail 100 and/or the modular rail 300 is constructed on site (e.g., being extruded in place using a slip-form extrusion machine). In another example, the extrusion speed of the slip-form extrusion machine is varied. In yet another example, the extrusion speed should be slow enough to produce the one or more mounting surfaces 110 and/or the mounting surface 310 with a high planarity and little sagging to allow for uniformity of a PV module mounting system. In yet another example, if a large planarity tolerance for the one or more mounting surfaces 110 and/or the mounting surface 310 could be allowed, a much higher extrusion speed of slip-form extrusion machine could be achieved, causing reduction of the construction cost of the finished rail.
When mounting one or more PV modules 200 to the modular rail 100 and/or the modular rail 300, the mounting system must meet one or more complex requirements. For example, the mounting system must provide sufficient mechanical strength to prevent the PV module 200 from being blown off the modular rail 100 and/or the modular rail 300 in the presence of wind forces. In another example, the mounting system is resistant to upward wind force on the PV module 200. In yet another example, the mounting system is resistant to downward wind force on the PV module 200. In yet another example, the mounting system is resistant to wind force equivalent to a uniform load of +/−2400 Pa across the PV module 200. In yet another example, the mounting system is able to last in an outdoor environment with extremes of weather for at least 25 years. In yet another example, the mounting system is resistant to hail of up to 2.5 cm in diameter traveling at speeds of up to 23 m/s. In yet another example, the mounting system is resistant to heavy snow loads on top of the PV module 200. In yet another example, the snow loads vary from 200 Pa to 5400 Pa across the PV module. In yet another example, the mounting system remains attached to the one or more mounting surfaces 110 and/or the mounting surface 310 at various temperatures. In yet another example, the mounting system functions at air temperatures ranging from −40° C. to +60° C. In yet another example, the mounting system functions at air temperatures ranging from −60° C. to +90° C. In yet another example, the mounting system functions with PV modules 200 at temperatures of up to +85° C. In yet another example, the mounting system functions with PV modules 200 at temperatures of up to +110° C. In yet another example, the mounting system remains attached to the one or more mounting surfaces 110 and/or the mounting surface 310 under various moisture conditions. In yet another example, the mounting functions after being subjected to +85° C. air at 85% relative humidity for 1000 hours. In yet another example, the mounting system is resistant to ultraviolet (UV) light. In yet another example, the mounting system is not highly flammable. In yet another example, the mounting system is resistant to one or more of salt air, carbonic acid rain, sulfuric acid rain, oily contamination, oxidation, galvanic corrosion, agricultural airborne ammonia, and the like.
In yet another example, the mounting system does not have exposed conductive surfaces to eliminate the need for electrical bonding and/or grounding. In yet another example, the mounting system remains attached to the one or more mounting surfaces 110 and/or the mounting surface 310 with the varying textures. In yet another example, the varying textures include differences in a surface height from 1 nm to 10 mm. In yet another example, the mounting system remains attached to the one or more mounting surfaces 110 and/or the mounting surface 310 during different stages of curing of the concrete material. In yet another example, the one or more mounting surfaces 110 and/or the mounting surface 310 cure within 5 days. In yet another example, the one or more mounting surfaces 110 and/or the mounting surface 310 cure within 30 days. In yet another example, the mounting system must be able to attach well to the one or more mounting surfaces 110 and/or the mounting surface 310 that may vary in planarity (e.g., due to sagging) by as much as 20 mm across the area to which the PV module 200 is mounted.
In yet another example, the mounting system must be able to attach well to the glass surface of the PV module 200. In yet another example, the mounting system must be flexible enough to be able to reduce the stress on the PV module 200 caused by the heating of the PV module 200 while the modular rail 100 and/or the modular rail 300 to which it is mounted remains colder. In yet another example, the mounting system is flexible enough to allow up to 2 mm of differential movement between the PV module 200 and the modular rail 100 and/or the modular rail 300. In yet another example, the mounting system is flexible enough to support the PV module 200 without damage when a temperature differential between the PV module 200 and the modular rail 100 and/or the modular rail 300 is as high as 100° C. In yet another example, the mounting system allows lateral movement (e.g., in a direction substantially parallel to the face of the PV module 200) between the PV module 200 and the modular rail 100 and/or the modular rail 300 to which it is mounted. In yet another example, the mounting system must be able to support the weight of the PV module 200 in a substantially vertical direction. In yet another example, the weight of the PV module 200 varies between 5 kg and 50 kg. In yet another example, if the mounting system includes one or more adhesive materials that are applied in the field, the one or more adhesive materials must have a rapid curing time under the weather conditions (e.g., temperature, moisture, wind load) at the time of application of the one or more adhesive materials in the field. In yet another example, the one or more adhesive materials cure within 5 days. In yet another example, the one or more adhesive materials cure within 30 days. In yet another example, any portion of the mounting system attached to the PV module 200 in the factory needs to have a low profile so as not to significantly reduce the number of PV modules 200 that is packed in a single shipping crate.
FIG. 5 is a simplified diagram showing the modular rail 300 prepared for the mounting of a PV module according to one embodiment of the present invention. This diagram is merely an example, which should not unduly limit the scope of the claims. One of ordinary skill in the art would recognize many variations, alternatives, and modifications. In FIG. 5, the modular rail 300 is shown with its mounting surface 310 prepared for the mounting of a PV module. For example, the mounting surface 310 has one or more holes 510 located at intervals along the length of the mounting surface 310. In another example, the one or more holes 510 have a substantially uniform size. In yet another example, the one or more holes 510 have a substantially uniform depth. In yet another example, the one or more holes 510 vary in size from 5 mm to 100 mm. In yet another example, the one or more holes 510 vary in depth from 5 mm to 500 mm. In yet another example, the one or more holes 510 vary in depth from 5 mm to 100 mm. In yet another example, the one or more holes 510 are arranged using a predetermined pattern and spacing.

This diagram is merely an example, which should not unduly limit the scope of the claims. One of ordinary skill in the art would recognize many variations, alternatives, and modifications. As shown in FIG. 6, the PV module 200 is mounted on the mounting surface 310 above the one or more holes 510 according to some embodiments.
As discussed above and further emphasized here, FIGS. 5 and 6 are merely examples, which should not unduly limit the scope of the claims. One of ordinary skill in the art would recognize many variations, alternatives, and modifications. For example, the modular rail 100 is substituted for the modular rail 300. In another example, the one or more holes 510 are located at regular intervals along the length of the one or more mounting surfaces 110.
FIG. 7 is a simplified diagram showing a partial cut-away view of a flexible rod used as part of the PV module mounting system according to one embodiment of the present invention. This diagram is merely an example, which should not unduly limit the scope of the claims. One of ordinary skill in the art would recognize many variations, alternatives, and modifications. As shown in FIG. 7, a flexible rod (e.g., a flexible joining material) 700 includes an inner core 710. For example, the inner core 710 includes one or more fibers. In another example, the one or more fibers are substantially parallel. In yet another example, the one or more fibers are braided. In yet another example, the one or more fibers are each selected from a group consisting of Aramid (Kevlar), polyester, ultrahigh molecular weight polyethylene (UHMWPE), nylon, viscose rayon, cotton, and the like. In yet another example, the one or more fibers do not include any brittle materials (e.g., certain ceramics, certain metals, and/or certain plastics). In yet another example, the one or more fibers do not include any stiffer fiber materials (e.g., certain carbon materials, certain fiberglass materials, and/or Polybenzobisoxazole (PBO)).
In some embodiments, the inner core 710 is surrounded by an inner jacket 720. For example, the inner jacket 720 runs the entire length of the flexible rod 700. In another example, the inner jacket 720 completely surrounds the inner core 710 except at each of the ends of the flexible rod 700. In yet another example, the inner jacket 720 is cross-braided. In yet another example, the inner jacket 720 includes one or more materials selected from a group consisting of Aramid (Kevlar), polyester, ultrahigh molecular weight polyethylene (UHMWPE), nylon, viscose rayon, cotton, and the like. In yet another example, the inner jacket 720 includes an ultraviolet (UV) light stable material. In yet another example, the inner jacket 720 protects the one or more fibers in the inner core 710 from moisture and/or UV light. In yet another example, the inner jacket 720 extends the practical lifetime of the flexible rod 700. In yet another example, the inner jacket 720 adds stiffness to the flexible rod 700. In yet another example, the inner jacket 720 increases the weight that the flexible rod 700 can support.
In some embodiments, the inner jacket 720 is surrounded by an outer jacket 730. For example, the outer jacket 730 runs the entire length of the flexible rod 700. In another example, the outer jacket 730 completely surrounds the inner jacket 720 except at each of the ends of the flexible rod 700. In yet another example, the outer jacket 730 is cross-braided. In yet another example, the outer jacket 730 includes one or more materials selected from a group consisting of Aramid (Kevlar), polyester, ultrahigh molecular weight polyethylene (UHMWPE), nylon, viscose rayon, cotton, and the like. In yet another example, the outer jacket 730 is omitted. In yet another example, the outer jacket 730 adds stiffness to the flexible rod 700. In yet another example, the outer jacket 730 increases the weight that the flexible rod 700 can support. In yet another example, a tightness of the outer jacket 730 is adjusted to control the amount of weight that the flexible rod 700 can support. In yet another example, the outer jacket 730 provides abrasion and/or chafing resistance to the flexible rod 700.
According to some embodiments, a size and/or materials included in the flexible rod 700 are chosen to meet one or more desirable properties. For example, the size and/or materials are selected to provide suitable pull strength to withstand the wind loads to which the PV module will be subjected. In another example, the size and/or materials are selected to provide sufficient stiffness so that the flexible rod 700 supports its share of the weight of the PV module 200. In yet another example, the size and/or materials are selected to provide the lateral flexibility due to lateral movement between the PV module 200 and the modular rail to which it is mounted. In yet another example, the size and/or materials are selected to provide the lateral flexibility and lateral strength needed to withstand the large amount of bending movement that occurs many times and/or for many cycles as the mounting system is subjected to thermal and/or wind loads. In yet another example, the size and/or materials are selected to withstand a large amount of sheer movement and sheer stresses that occurs many times and/or for many cycles as the mounting system is subjected to thermal and/or wind loads.
FIG. 8 is a simplified diagram showing a side view of a PV module mounting system using a flexible rod according to one embodiment of the present invention.

One of ordinary skill in the art would recognize many variations, alternatives, and modifications. In some embodiments, the number of notched mounts 2400 and corresponding ribbed posts 2500 is varied.

This diagram is merely an example, which should not unduly limit the scope of the claims. One of ordinary skill in the art would recognize many variations, alternatives, and modifications. As shown in FIG. 27, the method 2700 includes a process 2710 for attaching one or more ribbed posts to a PV module, a process 2720 for forming a modular rail, a process 2730 for inserting one or more notched mounts into the modular rail, and a process 2740 for inserting the one or more ribbed posts into the one or more notched mounts. According to certain embodiments, the method 2700 of mounting a PV module to a modular rail using one or more notched mounts and one or more ribbed posts is performed using variations among the processes 2710-2740 as would be recognized by one of ordinary skill in the art.
At the process 2710, one or more ribbed posts 2500 are attached to a PV module 2610. For example, the PV module 2610 is the PV module 200. In another example, the one or more ribbed posts 2500 are attached to the PV module 2610 using one or more adhesive materials. In yet another example, the one or more adhesive materials form a flexible bond between each of the one or more ribbed posts 2500 and the PV module 2610.

In another example, the modular rail 2620 is formed in-situ in the field using a slip-form extrusion machine. In yet another example, the extrusion speed of the slip-form extrusion machine is varied. In yet another example, the extrusion speed should be slow enough to produce one or more mounting surfaces which are substantially planar. In yet another example, the extrusion speed should be slow enough to produce the one or more mounting surfaces with a high planarity and little sagging to allow for uniformity in the PV module mounting system. In yet another example, if a large planarity variability in the one or more mounting surfaces could be allowed, a much higher extrusion speed of slip-form extrusion machine could be achieved, causing reduction of the construction cost of the finished rail. In yet another example, the modular rail 2620 is preformed in the factory and transported to the installation site.
At the process 2730, the one or more notched mounts 2500 are inserted into the modular rail 2620. For example, the process 2730 occurs before the modular rail 2620 is substantially cured. In another example, the process 2730 is controlled so that the depth to which each insertable end 2430 of each of the one or more notched mounts 2500 is inserted into the modular rail 2620 is adjusted to account for variations in the height of the modular rail 2620 and/or the desired angle of the PV module 2610 relative to the sun. In yet another example, the process 2730 is controlled so that the insertable end 2430 of each of the one or more notched mounts 2500 is inserted a suitable distance into the modular rail 2620 so that after the modular rail 2620 substantially cures, the one or more notched mounts 2400 provide sufficient pull strength to account for the wind loads to which the PV module 2610 is subjected.
At the process 2740, the one or more ribbed posts 2500 are inserted into the one or more notched mounts 2400. For example, an angle of each mounting flange 2410 of each of the one or more notched posts 2400 is adjusted using the corresponding rotatable joint 2440 to account for variations in the height of the modular rail 2620 and/or the desired angle of the PV module 2610 relative to the sun. In another example, each of the one or more ribbed posts 2500 is inserted into a corresponding receiving notch 2420 of one of the one or more notched mounts 2400. In yet another example, each of the one or more ribbed posts 2500 is inserted into a corresponding receiving notch 2420 of one of the one or more notched mounts 2400 at a position corresponding to one of the one or more grooves 2520 on each of the one or more ribbed posts 2500. In yet another example, each of the narrowed ends 2450 aids in aligning each of the one or more receiving notches 2420 with a corresponding one of the one or more grooves 2520. In yet another example, each of the flared openings 2460 aids in aligning each of the one or more receiving notches 2420 with a corresponding one of the one or more grooves 2520. In yet another example, each of ribbed posts 2500 is held in place at the corresponding post retaining end 2480 by the corresponding neck 2470. In yet another example, each of ribbed posts 2500 is clicked into position at the corresponding post retaining end 2480. In yet another example, one or more adhesive materials are applied to each of the ribbed posts 2500 and/or each of the post retaining ends 2480 prior to inserting each of the one or more ribbed posts 2500 into a corresponding one of the one or more notched mounts 2400.
