Solar Panel Backsheet

The panel s backsheet serves the same function that wire insulation serves in household wiring.

Solar panel backsheet. Most backsheets are made from petroleum based plastics. A backsheet is a required insulating film in all solar photovoltaic panels. Tedlar pvf backsheets maintain low 0 05 defect rates despite being the oldest installations dating back 35 years. Why do we need a solar backsheet in a pv panel.

The solar backsheet plays a significant role in a solar pv panel. Welcome to the world s most advanced solar backsheet product directory. On the other hand ethylene vinyl acetate also known as eva provides encapsulation for solar cells. 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.

To date dupont has surveyed over 4 2 million panels from 275 solar fields and 79 module manufacturers accounting for over 1 04 gw. I ll show you a picture. Panel manufacturers can use our advanced technical filters to find the exact solar backsheet that match their needs. The backsheet is typically a laminate of different polymer materials.

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. To insulate and protect the user from shock and provide the most reliable and efficient electrical conductivity possible. We have collated backsheet data from manufacturers from all around the world into a common template allowing you to compare and review backsheets easily. The backsheet is the outermost layer of the pv module placed at the non sunny side of it.

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. 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. They say one of them s worth a thousand words although i m such a succinct writer it s more like 240. Pvdf and polyamide backsheet defects increased by 51 and 18 since last year.

Our site features a company directory profiling 53 047 solar manufacturers sellers and solar panel installers. A solar panel backsheet is the white plastic at the back of a solar panel. 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.
