Wedge spring clip mounting system for photovoltaic modules

1. A photovoltaic (PV) mounting system comprising:

a substantially planar base portion comprising a roof-facing surface configured to face a roof, and a module-facing surface, opposite the roof-facing surface, configured to face a photovoltaic module, wherein the base portion comprises a lip circumscribing a perimeter of the base portion and curving inward over the module-facing surface;

a clamp comprising a spring base and a pair of clamping flanges extending upwardly from the spring base;

a support beam comprising a pair of ledges engaged with retaining portions of the pair of clamping flanges of the clamp, wherein the support beam further comprises a bottom portion, wherein the bottom portion is in contact with and is supported by the lip, and wherein the bottom portion contacts and resiliently deforms the spring base spreading apart and wedging corner portions of the clamp between the lip and the module-facing surface attaching the clamp to the base portion; and

a PV module coupling device mechanically coupled to the support beam and configured for coupling to a frame of the photovoltaic module.

2. The PV mounting system of claim 1 , wherein the base portion comprises a circular puck having a through-hole configured for mounting the base portion to a structure by a mechanical fastener, and wherein the support beam overlaps the through-hole.

3. The PV mounting system of claim 1 , wherein the spring base is flattened by the support beam.

4. The PV mounting system of claim 3 , wherein the spring base applies a spring force urging the support beam against the retaining portions of the clamping flanges.

5. The PV mounting system of claim 1 , wherein the clamping flanges form a boxed structure extending upwardly from the base portion.

6. The PV mounting system of claim 1 , wherein the clamping flanges comprise teeth configured for gripping the support beam and preventing lateral displacement of the support beam relative to the clamp.

7. The PV mounting system of claim 1 , wherein the photovoltaic module coupling device comprises a clamping-style connector.

8. The PV mounting system of claim 1 , wherein the photovoltaic module coupling device comprises a rock-it connector.

9. A photovoltaic (PV) mounting system comprising:

a base portion comprising a module-facing surface and a lip curving inward over the module-facing surface;

a clamp comprising a spring base and a pair of clamping flanges; and

a support beam configured as a mount for a PV module coupling device,

wherein the support beam is positioned between the clamping flanges and the support beam contacts and resiliently deforms the spring base to cause the corner portions of the spring base to spread apart and be wedged between the lip and the module-facing surface.

10. The PV system of claim 9 , wherein the base portion comprises a circular puck adapted to mount to a structure via a mechanical fastener.

11. The PV system of claim 9 , wherein the pair of clamping flanges comprises a boxed structure for holding the support beam.

12. The PV system of claim 9 , wherein the spring base urges the support beam away from the base portion and wherein the pair of clamping flanges comprises a pair of ledges that maintain the support beam in position to resiliently deform the spring base.

13. The PV system of claim 9 , wherein the pair of clamping flanges comprises teeth engaging the support beam and preventing lateral displacement of the support beam relative to the clamp.

14. The PV system of claim 9 , wherein the support beam comprises an elongated boxed beam.

15. A photovoltaic (PV) mounting system comprising:

a base portion comprising a module-facing surface and a lip curving inward over the module-facing surface;

a clamp comprising a spring base formed as a spring, wherein the spring base is in contact with the module-facing surface; and

a support beam configured as a mount for a PV module coupling device, wherein the support beam is held within the clamp and contacts the spring base, and wherein the clamp is locked to the base portion with corner portions of the spring base being wedged between the lip and the module-facing surface without the use of separate mechanical fasteners.

16. The PV system of claim 15 , wherein the clamp comprises flanges that extend upwardly from the spring base of the clamp.

17. The PV system of claim 15 , wherein the spring base of the clamp comprises an arch.

18. The PV system of claim 17 , wherein the arch is contacted by and flattened by the support beam when the base of the clamp is locked in to the base portion.

19. The PV system of claim 18 , wherein the clamp includes retaining portions engaged with the support beam for maintaining resilient compression of the arch by the support beam.
