Solar panel 12V/40W polycrystalline

Photovoltaic solar panel 12V/40W polycrystalline
Photovoltaic panel made of polycrystalline silicon. Aluminum frame 25mm, cover glass.

Polycrystalline cell:
Substrates are made from smaller silicon crystals and pressed into one unit.
The round ingot is then cut into so called wafers, which are cut to the desired PV cell size.
Obviously, this technology cannot achieve such purity of the material;

Advantages of polycrystalline:
Slightly higher diffuse light production (unfavorable light conditions)
