PV Fire Testing to UL1703 - Fact Sheet

Flat-plate photovoltaic (PV) modules and panels sold in the United States must comply with the regulations in safety standard ANSI/UL 1703 for fire resistance testing. Updates to this standard have required many manufacturers to incorporate new and different testing procedures, or to re-test previously tested products.

Intertek’s quick tip sheet, “Photovoltaic Panel and Module Fire Resistance Testing: Quick Facts about ANSI/UL 1703,” provides an overview of the information you need to understand the new regulations.
