Types of Commercial Solar Panels and their structures
Epoxy Resin Laminated Solar panel
Epoxy is a type of liquid resin known for its good adhesive properties and resistance to water degration. That is why they are used for laminating solar cells and is also used in boat building too. They are usually identified by their amber or slight brown colour. They also have high electrical insulation and good chemical resistance. However, in the long run, they can age prematurely under the Sun, turning yellowish and become more brittle.
When the solar cell is ready for encapsulation, it is placed on the backing material and the liquid epoxy resin is poured over the cells and the connecting ribbons. These layers will be laminated together at a temperature of 50 to 60 degrees Celcius and will form a harden layer when it cools.
- High strength
- Impact resistant
- High electrical insulation
- Attractive appearance
It is a low-cost product which has been traditionally used used for solar lights, solar toys, solar educational kits for kids and students in schools which has less demanding performance requirements. It is usually used for low voltage and low power applications.
