6 FAQs about [National Standard for Photovoltaic Panel Backsheet]

What is a solar backsheet?

The outer layer of a solar panel that serves as the primary defense for solar module components, particularly the solar cells, is known as a solar backsheet. It works by safeguarding solar panels against different and severe environmental conditions, UV radiation, moisture, dust, etc., throughout their lifespan.

What is a PV backsheet?

A PV backsheet is a special layer that covers the back of a solar panel. Its primary role is to protect the solar cells and internal components, enhancing the panel’s performance and extending its lifespan. Typically, backsheets are made from multiple layers of composite materials, including polymers, fluoropolymers, and polyester.

What are back-sheet materials for photovoltaic modules?

Back-sheet materials for photovoltaic modules serve several purposes such as providing electrical insulation, environmental protection and structural support. These functions are essential for modules to be safe for people working near them and for the structures to which they are attached.

Do you need a backsheet for solar panels?

In most cases, normal backsheets are sufficient to meet the requirements of PERC (Passivated Emitter Rear Cell) solar panels. However, when it comes to N-type or N-type TOPCon (Tunnel Oxide Passivated Contact) solar panels, a more specialized approach is necessary.

What is a solar backsheet Directory?
