Solar Panel Backsheet

Its primary purpose is to protect the solar panel components specifically the solar cells and wires from environmental elements such as stress or moisture which can degrade the 20 year life of solar panels.

Solar panel backsheet.

A solar panel backsheet is the white plastic at the back of a solar panel. Welcome to the world s most advanced solar backsheet product directory. Enf solar solar companies and products welcome to enf solar. While the backsheet contributes only 4 5 of the total cost of a solar panel the criticality of a solar panel backsheet is quite high compared to its cost contribution.

On the other hand ethylene vinyl acetate also known as eva provides encapsulation for solar cells. A solar backsheet is the last layer at the bottom of the solar pv panel and is typically made of a polymer or a combination of polymers. Our site features a company directory profiling 53 047 solar manufacturers sellers and solar panel installers. Tedlar pvf backsheets maintain low 0 05 defect rates despite being the oldest installations dating back 35 years.

I ll show you a picture. The backsheet is typically a laminate of different polymer materials. And a product directory presenting 76 124 products datasheets and pictures please use the navigation bar at the top of the screen to find the right category of solar company or solar product. Why do we need a solar backsheet in a pv panel.

A backsheet is a required insulating film in all solar photovoltaic panels. The solar backsheet plays a significant role in a solar pv panel. The backsheet is the outermost layer of the pv module placed at the non sunny side of it. A solar backsheet is the last layer at the bottom of the solar pv panel and is typically made of a polymer or a combination of polymers.

One of the lessvisible but essential components of a solar panel to their long term performance is backsheets. To date dupont has surveyed over 4 2 million panels from 275 solar fields and 79 module manufacturers accounting for over 1 04 gw. They say one of them s worth a thousand words although i m such a succinct writer it s more like 240. To insulate and protect the user from shock and provide the most reliable and efficient electrical conductivity possible.

Most backsheets are made from petroleum based plastics. Pv backsheet material solution for photovoltaic manufacturing the pv backsheet material you choose for your solar panel will have a considerable impact on how it withstands the elements and performs over the course of its lifetime. The panel s backsheet serves the same function that wire insulation serves in household wiring.
