 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.

    Our company designs and produces small solar panel with different specification and size. We utilize high transparent epoxy resin to encapsulate small solar panel and employ high-intensity and anti-distorting PCB board (hard pasteboards and glass fiber boards) as baseboard. We import different famous-brand solar cells (125/156) for solar panel. Our epoxy resin solar panel is UV resistant and yellowing resistant. All of our epoxy resin solar panels are environment friendly and fulfill ROSH directives.

   Small solar panel ranges 0.1W to 2W in general, has different size and shape. It has wide applications and can be used to various electronic products and lighting products. We can design and produce small solar panel and control circuit. Control circuit avoids battery of electronic products and lighting products overcharging and over-discharging.
