Dymat - Thin Film Backsheet for Floating Systems
Coveme offers different types of backsheets that are suitable for installations of photovoltaic modules on floating systems. The range includes both backsheets with an aluminum layer inside them, and backsheets with a barrier film, without the aluminum layer.
The aluminum-based dyMat® backsheet has an extremely low WVTR value and provides excellent protection for solar cells that are particularly sensitive to humidity. It is the right solution for thin film (CIGS and a-SI), flexible and even c-SI photovoltaic modules, where resistance to high temperatures and humidity is essential.
DyMat® barrier film backsheets are manufactured with an innovative integrated barrier layer which gives the backsheet a low WVTR value. These laminates have been specifically designed to be used in heterojunction cells but can also be used for floating systems with all types of cells. Furthermore, these laminates, not having an aluminum layer, facilitate the production process of assembling the module.
They are available in white, black or transparent (only barrier film without Aluminium) versions for installations up to 1500 VDC.
