Abstract

A photovoltaic module mounting system may include a right-hand support runner and a left-hand support runner. The support runners collectively define a rooftop contacting plane and a photovoltaic module support plane oriented at a predetermined angle relative to the rooftop contacting plane. The support runners may be interconnected with each other, and with additional support runners, to form an interconnected support structure that can be used to mount an array of photovoltaic modules upon a planar surface such as a building rooftop.

4. The system of claim 1, further comprising the photovoltaic module held in place by the first and second module clamp assemblies of the right-hand support runner and the first and second module clamp assemblies of the left-hand support runner.

5. The system of claim 4, further comprising electrical wiring passing through at least portions of the hollow tubing and configured to electrically interconnect the photovoltaic module to an adjacent photovoltaic module.

6. The system of claim 1, further comprising a u-shaped cross member having distal ends configured to be respectively joined to the transverse module support portions of each support runner, and a central portion configured to be oriented to lie in the rooftop contacting plane.

7. The system of claim 6, wherein each distal end of the u-shaped cross member is configured to be attached to a rooftop-facing portion of one of the module clamp assemblies.

8. The system of claim 6, further comprising a ballast pan configured to overlay the central portion of the u-shaped cross member and to receive one or more ballast stones.
