[PDF Version]FAQs about Specification requirements for photovoltaic support scaffolding
What is the minimum array area requirement for a solar PV inverter?
Although the RERH specification does not set a minimum array area requirement, builders should minimally specify an area of 50 square feet in order to operate the smallest grid-tied solar PV inverters on the market.
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 documents should be included in a solar roof plan?
At a minimum, these documents must include specific documentation of dead loads, live loads, wind loads, and, where applicable, snow loads for the existing roof design. These plans will provide important information for the solar designer when the homeowner decides to install a system.
