PET (also known as Polyethylene terephalate) is a type of plastic which is commonly used for bottled water, takeaway containers and household products due to their material stability, wear resistant and non-toxic nature. It’s high transparency and good scratch resistant also makes it suitable as a protective layer above the solar cell. Solar cells used can be monocrystalline or polycrystalline.

This allows good sunlight absorption while keeping the solar panel lightweight (compared to glass laminated solar panels)

The PET laminated solar panel is made by placing layers of PET, EVA, solar cell and PCB together. They are then laminated by machine at a temperature of 135 degrees Celcius which will melt the encapsulating materials together to form a watertight bond.
