6 FAQs about [What is EVA on the back panel of a photovoltaic panel]

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 Eva in solar cells?

Solar cells are sensitive to moisture, oxygen and weather. EVA is a component in a solar module that prevents air and moisture from reaching solar cells and degrading it. If not protected, solar cells will degrade with time and lose their ability to produce energy. What are EVA films?

What is solar Eva film?

Solar EVA films protect solar panels for long time with little loss in performance. A Solar EVA sheet is a milky-white coloured rubbery substance. On heating, it becomes a transparent protective film, sealing and insulating the solar cells.

Why do solar cells need an EVA sheet?

Afterward, a tough and long-lasting EVA sheet is used to cover the cells’ lower side once more. The back sheet completely encloses it. Moisture, oxygen and the environment can all damage solar cells. A solar module’s EVA stops air and moisture from getting to the solar cells and deteriorating them.

Why is Eva a good material for solar panels?
