How does SolarAPP+ identify local fire conditions qualified for Class A, B, C assemblies to comply with IRC R324.4.2?

SolarAPP+ only allows Class A fire rating for racking equipment, so it is not possible to install racking equipment that is only B or C rated. That equipment cannot be entered/selected in SolarAPP+. As such, we already pre-qualify racking equipment to Class A. As such, any system that goes through SolarAPP+ must be Class A rated regardless of location.

We do require load calcs for all equipment, and those load calcs must also be provided/made available at time of inspection.
