There are two packaging methods for solar panels, one is drip adhesive solar panels (epoxy resin encapsulation), and the other is laminated solar panels (glass/PET/ETFE encapsulation). What is the difference between them?
Production process
Drip glue solar panel: (1) Mix two different types of glue evenly in proportion. (2) Put the prepared glue into the glue dripping device, and then drip it onto the surface of the battery cell. (3) After the infusion is completed, perform vacuum pumping. (4) After vacuuming, perform baking and cure the surface epoxy resin adhesive. (5) Remove excess glue.
Laminated solar panels: (1) The surface is encapsulated with glass, PET, or ETFE prepared in advance. (2) Laminate the glass/PET/ETFE/+EVA+battery cells+EVA+back material once. (3) After completing the lamination, place it in a laminating machine for lamination (temperature and time should be within the specified range to prevent delamination) (4) Remove excess glue after lamination.
power
The power of drip glue solar panels is generally 0.1W-6W, which is applied in small-scale usage scenarios such as solar lawn lights, solar wall lights, solar handicrafts, solar toys, solar radios, solar flashlights, solar phone chargers, solar small water pumps, etc.
Laminated solar panels can have a power range of over 30mW-500W and can be customized for applications such as solar sights, solar cameras, solar RVs, and solar portable lights according to customer requirements.
service life
The service life of a dropper solar panel is 2-3 years, and the transparent dropper on the surface will gradually turn yellow over time, further affecting the service life of the solar panel. The lifespan of laminated solar panels is determined by their surface material. PET solar panels have a lifespan of 3-5 years, ETFE solar panels have a lifespan of 5-10 years, and glass solar panels have a lifespan of 25 years. The lifespan of laminated panels is much higher than that of adhesive solar panels.
Price
The drop glue solar panel at the same power will be lower than the laminated solar panel, which is determined by its own material, service life, and safety. The choice of solar panels should be considered based on the customer’s own product needs and the pricing of the entire product.
