PV Modules Certification

PV Modules

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’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:

  • PV Module safety certification to UL 1703, UL 61730-1 and UL 61730-2
  • BIPV safety certification to UL 7130
  • Type approval to IEC 61730-1 and IEC 61730-2.
  • Performance testing ( IEC/UL 61215 series)
  • Salt mist corrosion ( IEC 61730)
  • Ammonia corrosion ( IEC 62716)
  • Dynamic mechanical load ( IEC 62782)
  • Potential Induced Degradation ( IEC 62804)
  • IAM and PAN files (IEC 61853 series)
  • AC Modules
  • Fire Testing

The expertise of UL’s technical team and our certifications and test reports are recognized around the world by regulatory bodies. We offer integrated test plans to assess products to the requirements for multiple countries concurrently as well as to the Standards for Safety that we write.

Our data acceptance programs enable customers to utilize test data from their own or other test facilities for UL safety certifications.

UL’s qualified test facilities around the world provide local service in a company’s own time zone and language

IEC / UL 61730 - The New Harmonized Standard for Safety

USA and International Access in One Standard

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.

Transitioning to the UL 61730 Safety Standard

Safety certification to UL1703 for existing products and the use of UL61730 for certification of new products provides the least disruptive path for the PV industry. The objective of UL and the standards technical panel (STP) decision to maintain only one standard is to allow manufacturers to continue to apply the UL mark on currently certified products until they are no longer produced, new products or changes to existing products must comply with UL61730 after Dec 4, 2019.
