Mounting systems for solar panels
Mounting systems for mounting solar panels to a surface are disclosed and can include panel clamp assemblies and rail clamp assemblies. Panel clamp assemblies can comprise a panel clamp having a base and arms extending from edges of the base, the base having an aperture, a rail clamp having a central portion with an aperture and two flexible tabs extending from the central portion on opposing sides of the aperture and a fastener threaded through the apertures such that that flexible tabs contact a head of the fastener and the arms extend in an opposite direction from the flexible tabs. Rail clamp assemblies can comprise a base member having a bottom and two side walls, the bottom having at least one aperture and each side wall having an elongated aperture, two clamping members and a fastener, wherein the side walls of the base member are positioned such that the opening is of sufficient size to receive the rail.
1. A panel clamp assembly configured to clamp a solar panel to a rail system, the panel clamp assembly comprising:
a panel clamp having a base and at least one arm extending from an edge of the base, the arm having a clamping end opposite the base, the base having an aperture therein;
a rail clamp having a central portion with an aperture therein and two flexible tabs extending from the central portion on opposing sides of the aperture; and
a fastener threaded through the apertures in the central portion and the base such that that flexible tabs contact a head of the fastener and the at least one arm extends in an opposite direction from the flexible tabs.
2. The panel clamp assembly of claim 1 , wherein the panel clamp has two arms extending from opposing edges of the base, the arms configured to each clamp an edge of adjacent solar panels.
3. The panel clamp assembly of claim 1 , further comprising a deformable portion positioned between and in contact with the panel clamp and the rail clamp.
4. The panel clamp assembly of claim 3 , wherein the deformable portion is a foam material.
5. The panel clamp assembly of claim 1 , wherein the central portion of the rail clamp has two step portions each at an opposing edge of the central portion, wherein a step of the step portion extends in a same direction as the flexible tabs.
6. The panel clamp assembly of claim 5 , wherein the flexible tabs have a ledge facing away from the fastener, and wherein the flexible tabs extend beyond the step such that the ledge is a predetermined distance from the step portion located on a same side of the aperture.
7. The panel clamp assembly of claim 1 , wherein the flexible tabs have a ledge facing away from the fastener, and wherein the flexible tabs extend from the central portion such that the ledge is a predetermined distance from a portion of the central portion located on a same side of the aperture.
8. The panel clamp assembly of claim 1 , wherein the fastener is a nut and a bolt.
9. The panel clamp assembly of claim 1 , wherein a head of the fastener and the flexible tabs are configured to be received in a channel within the rail and wherein the arm and clamping end of the panel clamp are configured to secure a solar panel to the rail.
