Abstract

A photovoltaic mounting system having an elongated connector base. The elongated connector base can included photovoltaic module connector portion for supporting a pair of elevated photovoltaic modules above the base. The base may include a captive screw system for holding a pair of mounting screws in place prior to installation and functioning as a screw guide during installation. An assistance clamp fits over the elongated base under the photovoltaic module connector portion to secure the elongated connector base to relatively narrow portion of a roof to provide lateral stability to the elongated connector base.

First claim

What is claimed is:

1. A photovoltaic mounting system comprising:
an elongated connector base having a bottom portion connected to a top roof portion, the top roof portion being flanked by side roof portions leading away from the top roof portion;
a photovoltaic module connector connected to a top portion of the elongated connector base;
an assistance clamp connected to a bottom portion of the elongated connector base, the assistance clamp having a pair of attachment tabs configured for supporting fasteners that connect to the side roof portions,
wherein the assistance clamp comprises a planar portion extending through a passage within the elongated connector base,
wherein each of the pair of attachment tabs project away from the planar portion, and
wherein each attachment tab is arranged to receive a mechanical fastener to secure opposite sides of the elongated connector base to the side roof portions.

2. The system of claim 1 , wherein the assistance clamp is vertically aligned with the photovoltaic module connector at one end of the elongated connector base.

3. The system of claim 1 , wherein the planar portion extends along a plane and wherein each of the pair of attachment tabs extend at non-zero angles with respect to the plane.

4. The system of claim 1 , wherein each of the pair of attachment tabs comprises a first portion configured to laterally stabilize the elongated connector base and a second portion angularly displaced from the first portion for receiving the mechanical fastener.

5. The system of claim 4 , wherein the first portion is tensioned between the second portion and the planar portion.

6. The system of claim 5 , wherein the first portion spans an air gap between the second portion and the planar portion.

7. A photovoltaic mounting system comprising:
an elongated connector base having a bottom portion connected to an elevated roof portion by at least one primary connector passing through the bottom portion, the elevated roof portion being flanked by side roof portions leading away from the elevated roof portion;
a photovoltaic module connector connected to a top portion of the elongated connector base; and
a tensioning strap passing through a passage within a bottom portion of the elongated connector base, the tensioning strap being placed into tension between fasteners that connect to the side roof portions.

8. The system of claim 7 , wherein the length to width ratio ranges from 5:1 to 10:1.

9. The system of claim 7 , wherein the bottom portion of the elongated connector base has a positive length to width ratio.

10. The system of claim 7 , wherein the strap is placed through elongated connector base to align with the photovoltaic module connector at one end of the elongated connector base.

11. The system of claim 7 , wherein the tensioning strap comprises first and second attachment tabs that angularly extend from elongated connector base.

12. The system of claim 11 , wherein each of the first and second attachment tabs comprise portions that are tensioned freely in air between the fasteners and the elongated connector base.

13. The system of claim 12 , wherein each of the first and second attachment tabs comprises fastener support portions having holes for receiving the fasteners, the holes being aligned with support bases positioned between the side roof portions and the fastener support portions.

14. The system of claim 13 , wherein the support bases are compressed between the side roof portions and the fastener support portions.
