Solar Energy Product Certification

As solar energy technologies advance, their continued safety, reliability and performance must be evaluated. As safety science experts, we help you navigate these risks through certification for photovoltaic (PV) modules and inverters, and compliance with a wide range of local, national and international standards.

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 an evaluation 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 Solutions’ wide range of services for PV modules cover all types – crystalline, thin-film, building-integrated PV (BIPV), concentrator PV.  As applicable, we certify to:

• PV Module safety certification to UL 1703, the Standard for Flat-Plate Photovoltaic Modules and Panels
• UL 61730-1, the Standard for Photovoltaic (PV) Module Safety Qualification
• UL 61730-2, Photovoltaic (PV) Module Safety Qualification - Part 2: Requirements for Testing
• BIPV safety certification to UL 1703, UL 790, UL 580, and UL 1897
• IEC 61730-1, IEC 61730-2 for Photovoltaic (PV) Modules and IEC 62108 for Concentrator Photovoltaic (CPV) Modules and Assemblies

The expertise of UL Solutions’ 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 approved test facilities for UL Solutions safety certifications.

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

Inverters

UL Solutions provides inverter certification and evaluation services for compliance with a wide range of local, national and international standards. The extent and scope of the testing are determined in part by whether the product is a standalone unit or intended for interconnection with a local utility.

We test power inverters, converters and controllers to the requirements of all key international and local grid standards, including:

• UL 1741 (Supplement SA and SB), the Standard for Inverters, Converters, Controllers and Interconnection System Equipment for Use With Distributed Energy Resources
• IEC 62109-1 and IEC 62109-2
• UL 62109
• IEEE 1547 and IEEE 1547.1
