Outside of the NEC, technicians need to be cognizant of the fire codes their jurisdictions enforce and how PV systems are regulated within those codes. The most common fire codes are NFPA 1, Fire Code and ICC’s International Fir. .
PV systems also have structural requirements and codes associated with them. Many jurisdictions use ICC’s International Building Code (IBC) and ASCE 7 to guide the structural components of a PV installatio. The most common code system designers, installers, and inspectors refer to for PV and ESS systems are NFPA 70, or the National Electrical Code (NEC). [pdf]
Minimum clearance between the PV module(s) and the roofing material must be at least 10 cm.
