From 600 to 1500 volt, DUNMORE is the experienced partner for your PV backsheet needs.


DUNMORE understands that PV backsheets are a critical dielectric component in improving your overall solar module performance. For over 30 years DUNMORE has been delivering next-generation, innovative products through:

  • DUN-SOLAR specialized PV backsheet product line
  • Custom solutions for unique module designs

DUNMORE offers DUN-SOLAR PV backsheets to the photovoltaic market as a component for the production of monocrystalline, polycrystalline, CPV and thin film solar modules. DUN-SOLAR PV backsheet materials protect photovoltaic modules from UV, moisture and weather. They insulate the electrical load of the modules, which can operate up to 1500 VDC. These functions are essential for the photovoltaic modules functionality, longevity and safety of people who work with and near the module.

To ensure that all PV-Modules meet the necessary requirements, they must pass the qualification standards such as IEC 61215, IEC 61730, IEC 61646 and UL 1703. DUN-SOLAR PV backsheet products are developed, produced and tested in conformance with all common standards and regulations. DUNMORE works very closely with the world famous Fraunhofer Institute for Solar Energy Systems ISE located in Freiburg Germany near our European headquarters and manufacturing plant also in Freiburg.

PV Backsheet Construction

DUN-SOLAR photovoltaic backsheet has a traditional three-layer design using only the highest quality materials. DUNMORE's superior adhesive and laminating technology provides exceptional bonding of all layers in the PV backsheet.

DUNMORE offers various PV backsheet constructions such as Military Spec TPT and TPE using DuPont Tedlar®, DUN-SOLAR PPE+ and Ultra-clear all polyester constructions and a range of specialty products for high voltage and thin film applications. In addition to our standard products, DUNMORE works with customers to develop products to meet their specific application needs.

All DUN-SOLAR PV backsheets are:
