Solar module production is more of an assemly line where different components of a solar module are assembled. For example-solar cells (mostly imported from China) are packed and connected in arrays, encapculants are used, solar glasses are used on the top and back to prevent from direct damage from water, cleaning and other threats. Silver pastes are also used in these modules. On the other hand, Alumunium frames are also used at the corners to make it easy to install and transport to give an additional sturdy support.
