MATERIALS

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.

How Do Solar Panels Work?

When photons hit a solar cell, they knock electrons loose from their atoms. If conductors are attached to

the positive and negative sides of a cell, it forms an electrical circuit. When electrons flow through such a

circuit, they generate electricity. Multiple cells make up a solar panel, and multiple panels (modules) can be

wired together to form a solar array. The more panels you can deploy, the more energy you can expect to

generate.
