Polycrystalline solar panel WDNY-280P72

Product description

Polycrystalline solar panel WDNY-280P72

Their structure is crystallized, as you can see it from their name. They are considered to be the industrial standard, as in general these panels are about twice as effective as amorphous cells.
As a rule, the effectiveness ratings range from 12-16%. Nowadays, the most common type of solar panels is the polycrystalline one.
These panels are a bit less effective than the single crystal, but if they are set into a framework with about 35 other cells, the practical difference measured in watts per square meter, or even foot, is not so much.
