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 mounting system, comprising:
(a) a first lower mounting base having at least one first photovoltaic module support;
(b) a second lower mounting base having at least one second photovoltaic module support;
(c) an upper mounting base positioned between the first lower mounting base and the second lower mounting base in a horizontal plane;
(d) a bar connecting the first lower mounting base to the second lower mounting base through the upper mounting base, the bar extending downward at an angle with respect to the horizontal plane from the upper mounting base to each of the first and second lower mounting bases; and
(e) a pair of sliding supports located on either side of the upper mounting base, each sliding support comprising a photovoltaic module connector, wherein each sliding support has an aperture to receive the bar passing therethrough, and wherein the aperture has a central longitudinal axis that extends in a direction that is not collinear with a central longitudinal axis of the bar.

2. The system of claim 1 , wherein each sliding support pivot locks onto the bar when the connector on the sliding support is secured to the upper side edge of a photovoltaic module.

3. The system of claim 2 , wherein each sliding support pivot locks onto the bar by being rotated about an axis that is perpendicular to the longitudinal axis of the bar.

4. The system of claim 1 , wherein the connector in the photovoltaic module support on the lower mounting base receives the lower side edge of a photovoltaic module pivot-dropped thereon.

5. The system of claim 4 , wherein the connector in the photovoltaic module support in the lower mounting base is a rock-it connector that is received into a side groove in a frame of the photovoltaic module.

6. The system of claim 4 , wherein the connector in the photovoltaic module support in the lower mounting base is a wrap-around connector that wraps around a frame of the photovoltaic module.

7. A method of assembling a photovoltaic array, comprising:
(a) positioning a first lower mounting base on a surface, the first lower mounting base having at least one first photovoltaic module support;
(b) positioning a second lower mounting base on the surface, the second lower mounting base having at least one second photovoltaic module support;
(c) positioning an upper mounting base on the surface between the first lower mounting base and the second lower mounting base along a horizontal plane between the first lower mounting base and the second lower mounting base; and
(d) connecting the first lower mounting base to the second lower mounting base through the upper mounting base with a bar, such that the bar extends downward at an angle, with respect to the horizontal plane, from the upper mounting base to each of the first and second lower mounting bases;
(e) placing a lower side edge of a photovoltaic module onto a connector on the first lower mounting support;
(f) lowering an upper side edge of the photovoltaic module towards the bar;
(g) sliding a sliding support on the bar down to a position adjacent to the upper side edge of the photovoltaic module, wherein the sliding support has an aperture which has a central longitudinal axis that extends in a direction that is not collinear with a central longitudinal axis of the bar; and then
(h) connecting the sliding support onto the upper side edge of the photovoltaic module.

8. The method of claim 7 , wherein the bar is snap-fit connected onto the upper and lower mounting supports.

9. The method of claim 7 , wherein connecting the sliding support onto the upper side edge of the photovoltaic module comprises pivot locking the sliding support onto the bar by rotating the sliding support about an axis that is perpendicular to the longitudinal axis of the bar and parallel to the upper side edge of the photovoltaic module.

10. The method of claim 7 , wherein lowering the upper side edge of the photovoltaic module towards the bar pivot locks the lower side edge of the photovoltaic module onto the connector on the lower mounting base.

11. The method of claim 7 , wherein lowering an upper side edge of the photovoltaic module towards the bar comprises moving the photovoltaic module to a position parallel to the bar.

12. The method of claim 7 , wherein placing a lower side edge of a photovoltaic module onto the connector on the lower mounting base comprises inserting the connector on the lower mounting support into a side groove in the lower side edge of the photovoltaic module.

13. The method of claim 7 , wherein connecting the sliding support onto the upper side edge of the photovoltaic module comprises inserting a connector on the sliding support into a side groove in the upper side edge of the photovoltaic module.

14. The system of claim 1 , wherein the upper mounting base is configured in part to define a peak of the photovoltaic mounting system.

15. The system of claim 1 , wherein the first lower mounting base is configured in part to define a valley of the photovoltaic mounting system.

16. The system of claim 1 , wherein the first lower mounting base comprises a pair of opposite facing photovoltaic module supports.

17. The system of claim 1 , wherein the bar comprises first and second bars coupled by a connector.
