 Epoxy solar panel structure

 

It is a traditional type small solar panel called epoxy resin encapsulated solar panel, which is sticked together by epoxy resin glue at a temperature 50~60 degree, you will see the epoxy resin coated panel have three layers,

1. Epoxy Resin AB Glue

2. Solar Cells

3. PCB Board

Features

1): Epoxy resin solar panel is made of monocrystalline or polycrystalline silicon. The encapsulation material are made of Epoxy Resin. Characterized by anti-humidity, insulation, excellent transparence and anti-aging, as well as smoothness, no bubble and neat apperance. Hard appearance; long-time life, high-performance to week light; widely used in lamp series, no power source sector.

2): Epoxy resin solar panels are easily to install; friendly environmental. High efficiency solar cells, Non-stick protective film.

3):Epoxy resin solar panels can be widely used in solar lawn lamps, solar toys, solar chargers and solar signal lights.
