Polymeric Frontsheets and Backsheets for Photovoltaic (PV) Modules

PV frontsheet and backsheet testing

Photovoltaic (PV) frontsheets and backsheets are among the most important PV module components to consider for safety testing. They provide electrical insulation and protect the inner components of a PV module from extreme environmental stress factors encountered during the intended lifetime performance of the module. As PV systems push into higher-voltage applications, the chance for premature failures of the frontsheets and backsheets also increases, raising additional safety concerns. To address these concerns, the IEC further expanded its testing requirements to include mechanical, electrical and visual tests after environmental stress exposures, outlined under IEC 62788-2-1* and the revised second edition of IEC 62788-2*.  

As a member of IEC technical committee 82 (TC 82), Solar Photovoltaic Energy Systems, UL Solutions can help you further understand the changes to the standards and meet compliance requirements. Our services include:  

• Frontsheets and backsheets testing according to the updated IEC requirements. 
• Performance testing of polymeric materials used for new PV constructions under the updated standards.
• Issuance of a UL Solutions Yellow Card for material recognition.
