PV modules are installed in extreme environments such as heavy snow, high winds or desert conditions. Innovative PV products are also replacing traditional building materials such as roof coverings and curtain walls. Installations such as these expose materials to stresses for which stakeholders need reassurance of the long-term safety of the system. Standards are a way of reducing risk by introducing consistency to essential design features that address safety requirements.
UL published the first PV Standard, ANSI/UL 1703, Safety of Flat-Plate Photovoltaic Modules and Panels, in 1986 and has since harmonized the standard resulting in resulting in UL 61730-1 and UL 61730-2. Collaboratively developed by manufacturers, code authorities, national labs, government agencies and other interests, the new PV module safety standard embodies requirements for advances in materials, increasing system voltages and innovative designs are addressed with new and updated construction and testing requirements.
UL’s wide range of services for PV modules cover all types – crystalline, thin film, building integrated PV (BIPV), concentrator PV – and provide expert assistance in areas such as:
