Backsheet Of Solar Panel

The backsheet is the outermost layer of the pv module placed at the non sunny side of it.

Backsheet of solar panel.

A reliable backsheet should be able to provide protection from moisture physical damage and uv rays while also minimizing the occurrence of electrical discharge and thermal. Companies involved in backsheet production a key sourcing item for solar panel manufacturers. Why do we need a solar backsheet in a pv panel. The leader in backsheet durability over time.

A poor quality solar backsheet can cause system degradation unwanted maintenance and. A backsheet is a required insulating film in all solar photovoltaic panels. The backsheet is typically a laminate of different polymer materials. Less than 0 05 of tedlar based backsheets showed defects in global field inspections.

Air side cracking on the bottom left occurs on the rear of solar panels and is the most common defect. 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 solar backsheet plays a significant role in a solar pv panel. The panel s backsheet serves the same function that wire insulation serves in household wiring.

The impact can be significant ranging from severe brand and reputation losses to bodily harm. Most backsheets are made from petroleum based plastics. Types of solar panel backsheet defects. The illustrations from the report below show the 5 different categories of backsheet defects and their frequency.

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. It is followed by cell side yellowing and cell side cracking. What does the backsheet do. 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.

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 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. One of the lessvisible but essential components of a solar panel to their long term performance is backsheets. Tedlar pvf film based backsheet is the industry standard for solar backsheets.

To insulate and protect the user from shock and provide the most reliable and efficient electrical conductivity possible.
