New UL-listed DUN-SOLAR™ backsheets for PV applications handle long-term UV exposure and wide temperature ranges

DUNMORE is proud to announce its expanded portfolio of UL listed backsheets for photovoltaic applications. The DUN-SOLAR™ products are designed and manufactured for solar applications where robust characteristics are needed, such as long term UV exposure and wide temperature ranges. By incorporating high performance materials into the coated and laminated films, DUN-SOLAR backsheets provide superior moisture resistance, thermal, and UV stability. These photovoltaic (PV) backsheets combine process stability with excellent functionality.  

With proven durability in the field, the expanded DUN-SOLAR portfolio of over 35 UL listed products includes polyester and polyvinyl fluoride film (PVF) constructions (https://www.dunmore.com/products/protective-backsheets.html) for 1000 volt and 1500 volt applications.  PV backsheets that meet California (UL 1703 Fire Rating) and IEC 61730) are available in clear, white, and black configurations. Also available are other new and unique DUNMORE backsheets, including the DS392R for Bifacial Modules and the DS450 and DS475 PPC+ backsheets, which allow for greater module output and manufacturing efficiencies.
