Abstract

A solar array with successive rows of photovoltaic modules angled in opposing directions forming peaks and valleys between the rows with the valleys (i.e.: lower sides of the photovoltaic module rows) being mounted close together and the peaks (i.e.: upper sides of the photovoltaic module rows) being mounted far apart to improve system aerodynamics and permit ease of access for installers. Included is a system for connecting the upper sides of the photovoltaic modules to connectors that slide on bars extending between upper and lower mounting bases and for pivot locking the lower sides of the photovoltaic modules to the lower mounting bases.

First claim

What is claimed is:

1. A photovoltaic array, comprising:
(a) a plurality of photovoltaic modules; and
(b) mounting hardware supporting the plurality of photovoltaic modules such that the photovoltaic modules are positioned in an array with successive rows of the photovoltaic modules being angled in opposing directions, wherein:
(i) upper side edges of adjacent photovoltaic modules are spaced apart a distance of between 18% to 50% of the width of a photovoltaic module; and
(ii) lower side edges of adjacent photovoltaic modules are spaced apart a distance of less than 20% of the width of a photovoltaic module; and

wherein the mounting hardware comprises:
a plurality of upper mounting bases;
a plurality of lower mounting bases with module supports thereon, the module supports holding lower side edges of the photovoltaic modules;
bars connecting the lower mounting bases to the upper mounting bases; and
sliding supports, each having an enclosed aperture configured to receive a bar, positioned on the bars, the sliding supports holding upper side edges of the photovoltaic modules, wherein the sliding supports are configured to slide along the length of the bars.

2. The array of claim 1 , wherein each of the plurality of photovoltaic modules in the array have the same dimensions.

3. The array of claim 1 , wherein the upper side edges of adjacent photovoltaic modules are spaced apart a distance of between 50 mm to 500 mm, and the lower side edges of adjacent photovoltaic modules are spaced apart a distance of less than 150 mm.

4. The array of claim 1 , wherein upper side edges of adjacent photovoltaic modules are spaced apart a distance of between 30% to 40% of the width of a photovoltaic module.

5. The array of claim 1 , wherein the plurality of lower mounting bases are connected together in pairs facing opposite directions.

6. The array of claim 1 , wherein no photovoltaic module touches another photovoltaic module.

7. The array of claim 1 , wherein four corners of four different photovoltaic modules are positioned adjacent to each upper mounting base.

8. The array of claim 1 , wherein the mounting hardware has a weight of less than 3 lbs/square foot.

9. The array of claim 1 , wherein the sliding supports each include an engaging portion configured to couple with the upper side edge of a photovoltaic module.

10. The array of claim 1 , wherein the enclosed aperture of each sliding support is configured to pivot such that a top edge and a bottom edge of the aperture locks the sliding support on the bar.

11. The array of claim 1 , wherein the enclosed aperture of each sliding support has a central longitudinal axis that is not collinear with a longitudinal axis of the bar.

12. The array of claim 1 , wherein each of the plurality of the photovoltaic modules is configured to pivot fit into the lower mounting bases.

13. The array of claim 1 , wherein each of the plurality of the photovoltaic modules is configured to rotatably fit into the upper mounting bases.

14. The array of claim 1 , wherein each of the plurality of the photovoltaic modules further comprises a groove configured to engage with the sliding supports.

15. A photovoltaic array, comprising:
(a) a plurality of photovoltaic modules; and
(b) mounting hardware supporting the plurality of photovoltaic modules such that the photovoltaic modules are positioned in an array with successive rows of the photovoltaic modules being angled in opposing directions
wherein the mounting hardware comprises:
a plurality of upper mounting bases;
a plurality of lower mounting bases with module supports thereon, the module supports holding lower side edges of the photovoltaic modules;
bars connecting the lower mounting bases to the upper mounting bases; and sliding supports, each having an enclosed aperture configured to receive a bar, positioned on the bars, the sliding supports holding upper side edges of the photovoltaic modules, wherein the sliding supports are configured to slide along the length of the bars.

16. The array of claim 15 , wherein each of the plurality of photovoltaic modules in the array have the same dimensions.

17. The array of claim 15 , wherein the upper side edges of adjacent photovoltaic modules are spaced apart a distance of between 50 mm to 500 mm, and the lower side edges of adjacent photovoltaic modules are spaced apart a distance of less than 150 mm.

18. The array of claim 15 , wherein upper side edges of adjacent photovoltaic modules are spaced apart a distance of between 30% to 40% of the width of a photovoltaic module.

19. The array of claim 15 , wherein the sliding supports each include an engaging portion configured to couple with the upper side edge of a photovoltaic module.

20. The array of claim 15 , wherein the aperture of each sliding support is configured to pivot such that a top edge and a bottom edge of the aperture locks the sliding support on the bar.

21. The array of claim 15 , wherein the aperture of each sliding support has a central longitudinal axis that is not collinear with a longitudinal axis of the bar.

22. The array of claim 15 , wherein each of the plurality of the photovoltaic modules is configured to pivot fit into the lower mounting bases.

23. The array of claim 15 , wherein each of the plurality of the photovoltaic modules is configured to rotatably fit into the upper mounting bases.

24. The array of claim 15 , wherein each of the plurality of the photovoltaic modules further comprises a groove configured to engage with the sliding supports.

25. The array of claim 15 , wherein upper side edges of a first row and a second row of the photovoltaic modules are spaced apart a distance of between 18% to 50% of the width of a photovoltaic module.

26. The array of claim 15 , wherein lower side edges of the second row and a third row of the photovoltaic modules are spaced apart a distance of less than 20% of the width of a photovoltaic module.
