What are PV solar protection rating grades?
PV solar protection rating grades, also known as fire rating grades, indicate the level of fire resistance for a PV system. Standards such as UL 1703 and IEC 61730 determine these grades by assessing flammability, ignition resistance, and flame spread on PV modules. PV systems typically have three fire rating grades: Class A, Class B, and Class C.
Are photovoltaic panels fire rated?
Effective January 1, 2015, Rooftop mounted photovoltaic panels and modules shall be tested, listed and identified with a fire classification in accordance with UL 1703. The fire classification shall comply with Table 1505.1 of the California Building Code based on the type of construction of the building.
How to minimise fire risk from solar PV systems?
The solar industry welcomes clarity on how to minimise fire risk from solar PV systems, which in absolute terms is extremely low. “The core way to mitigate any risk is to ensure the highest possible quality in the design, installation, operation, and maintenance of solar systems.
What are the fire rating standards for PV systems?
