Solar panel back film

What is a solar panel backsheet?

Solar panels are an excellent way to generate renewable energy, but they need the right type of backing. This is where solar panel backsheet materials come in. They are essential for protecting fragile solar cells from harsh weather conditions and other potential damage that may occur on the back exterior side of the PV module. [toc]

Why do you need a backsheet for a photovoltaic panel?

Photovoltaic (PV) modules need to be a reliable source of power for 25 years or more, so their components all need to work in concert to ensure the panel continues to perform. Backsheets help do that – they insulate the electrical components of the module, protecting them over their lifetime. Backsheet performance can be analyzed by:

What is the difference between Eva and photovoltaic backsheet?

Photovoltaic backsheets play an important role in protecting solar modules over their lifetime. On the other hand, EVA is an encapsulant for solar Cells/ Modules. It is a copolymer film which acts as an essential sealant of photovoltaic solar modules for ensuring the reliability and performance.

What is a solar backsheet & why is it important?

The backsheet, is a critical component in a solar module, since it is responsible for protecting and electrically insulating the module itself. The defects of the most concern for backsheets include cracking, yellowing and delamination.

What is Tedlar® PVF film-based backsheet?

Tedlar® PVF film-based backsheet is the industry standard for solar backsheets Tedlar® PVF film-based backsheet designs have been in the field for more than 30 years in different climates, including deserts, tropical locations, seashores, and mountainous terrains. They have protected millions of solar panels across multiple geographies.

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.
