They are designed for builders constructing single family homes with pitched roofs, which offer adequate access to the attic after construction. It is assumed that aluminum framed photovoltaic (PV) panels mounted on a “post” and rail mounting system, the most common in the industry today, will be installed by the homeowner.

How much weight does a PV system add to a roof?

A conventional PV system that includes racking materials will add approximately 6 pounds per square foot of dead load to the roof or structure, though actual weights can vary for different types of systems. Wind will add live loads; the magnitude of live loads will depend on the geographic region and the final PV system.

What are the requirements for solar panels on a low-slope roof?

Ballasted, unattached PV systems on low-slope roofs have to meet seven conditions to comply with seismic load requirements in Section 13.6.12. For low-profile systems, the height of the center of mass of any panel above the roof surface must be less than half the least spacing in plan of the panel supports, but in no case greater than 3 feet.

Do PV systems comply with the NEC?
