Polycrystalline Solar PV Modules

Polycrystalline modules have a somewhat lower silicon content, but are more environmentally friendly to manufacture. They therefore have a lower level of efficiency and need a greater surface area for the same output. Because the price per Watt often turns out lower, they are nevertheless frequently used for large installations. In terms of their service life and reliability, polycrystalline modules are in no way inferior to the others. The cells generally have a bluish colour with a glittery effect.
