Solar panel backsheet material. The panel s backsheet serves the same function that wire insulation serves in household wiring. 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. Why do we need a solar backsheet in a pv panel. On the other hand ethylene vinyl acetate also known as eva provides encapsulation for solar cells.

Most backsheets are made from petroleum based plastics. A key sourcing item for solar panel manufacturers. 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. The backsheet is typically a laminate of different polymer materials.

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. For solar pv module backsheets. Pvdf and polyamide backsheet defects increased by 51 and 18 since last year.

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. To insulate and protect the user from shock and provide the most reliable and efficient electrical conductivity possible. The material has to be waterproof and long lasting as most solar panels have performance warranties of 25 years. More than half the world s 900 million solar panels have dupont materials in them and dupont materials have been time tested in more than 11 trillion panel hours of outdoor solar field installations globally since 1975.

To date dupont has surveyed over 4 2 million panels from 275 solar fields and 79 module manufacturers accounting for over 1 04 gw. 2 solar panel backsheets are usually white because if the sheet visible between solar cells reflects sunlight the panel will be a little cooler and this aids efficiency. 84 backsheet manufacturers are listed below. A complete list of solar material companies involved in backsheet production for the crystalline panel process.

The solar backsheet plays a significant role in a solar pv panel.
