Kiwa PVEL's Backsheet Durability Sequence
Published 2019.
When the backsheets of PV modules are made with substandard materials or poor-quality construction methods, they are likely to degrade – and ultimately cause solar asset underperformance.
Kiwa PVEL requires the Backsheet Durability Sequence (BDS) as part of our industry-leading PV Module Product Qualification Program. The BDS provides buyers with the data they need to evaluate PV module backsheets. Our white paper explains how our BDS works and discusses what developers, investors and asset owners need to know about backsheet durability.
