Backsheet

The photovoltaic (PV) back sheet is a photovoltaic laminate that protects the photovoltaic (PV) module from UV, moisture and weather while acting as an electrical insulator. PV back sheets are available in a variety of constructions for both traditional rigid PV modules, as well as thin film PV modules and solar power concentrators.

Our photovoltaic  (PV) backsheets we offer are specifically designed with a robust construction, typically a traditional three layer(having a high performance three layer non-fluorinated construction with a hydrolysis resistant and UV stable PET finish layer applied to a polyester core and a PE laminated structure) laminate using only the highest quality materials for use in photovoltaic backsheet applications requiring superb electrical, physical, barrier and thermal properties to protect PV modules from UV, moisture and weather while insulating the electrical load of the modules, which can operate up to 1000 VDC.

Thin film photovoltaic backsheets we provide have properties to increase cell efficiencies, like reflectance and dielectric strength, as well as act as a barrier to ensure a long life of the module.

Regardless of the thin film technology, all of our  thin film photovoltaic backsheets are designed to aid in the production of lowest cost-per-watt modules as $/watt, conform to non flat surfaces promoting module flexibility and create a high vapor barrier to protect the thin film PV chemistry.

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. Our photovoltaic (PV) backsheet products have all common standards and regulations, remaining in line with market requirements.

Four different standard colors are available such as white, green, red and black(custom colors on request)
