Photovoltaic solar panel 12V/20W polycrystalline

Photovoltaic panel made of polycrystalline silicon. Duralumin frame 25mm, cover glass.

Polycrystalline cell:

He makes a substrate from smaller silicon crystals, which is pressed into a single unit.
The round ingot is then cut into so-called Wafers that are cut to the desired size of the PV cell.
Of course, this technology cannot achieve such purity of the material, transitions between crystals are visible in it.

Advantages of polycrystal:
Slightly higher yield of production from diffused light (adverse light conditions)

Technical parameters:
- Max. open circuit voltage Voc = 21.56V
- Max. short-circuit current Isc = 1.23
- Max. voltage at 20W load: Vmp = 17.56V
- Max. current at 20W: Imp = 1.14
- Max. system voltage: 1000V
- Working temperature -45 + 85°C
- Dimensions: 500 × 350 × 25 mm
