Plastic back sheet for photovoltaic panels

What are back-sheet materials for photovoltaic modules?

Back-sheet materials for photovoltaic modules serve several purposes such as providing electrical insulation, environmental protection and structural support. These functions are essential for modules to be safe for people working near them and for the structures to which they are attached.

Are all photovoltaic backsheets the same?

The mechanical, electrical, optical and chemical properties and durability of backsheets are critical to the long term reliability, durability and safety of the photovoltaic modules. However, not all backsheets are created equal.

Why do photovoltaic modules need a backsheet?

In photovoltaic modules, moisture accumulation can lead to the corrosion of metal parts. Backsheets act as a preventive mechanism to stop moisture and minimize the possibility of insulation degradation, short-circuiting, and corrosion of electrical connections or components.

What is a Dunmore photovoltaic backsheet?

DUN-SOLAR photovoltaic backsheet are designed with various constructions using only the highest quality materials. Dunmore's superior adhesive and laminating technology provides exceptional bonding of all layers in the PV backsheet along with superior UV stability. Typically, PV backsheets can be produced to your thickness requirements.

Why is PV backsheet important?

Therefore, PV backsheet is extremely important for increasing the durability of a PV module. The mechanical, electrical, optical and chemical properties and durability of backsheets are critical to the long term reliability, durability and safety of the photovoltaic modules.

Why do solar panels need backsheets?

Backsheets act as a preventive mechanism to stop moisture and minimize the possibility of insulation degradation, short-circuiting, and corrosion of electrical connections or components. Backsheets safeguard the electrical components of a solar module by providing insulation and ensuring their longevity.
