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) Technical parameters: - Max. open
circuit voltage Voc=21.58V - Max. short circuit current Isc=2.63A - Max. voltage
at 40W load: Vmp=17.31V - Max. current at 40W: Imp=2.31A - Max. system voltage:
1000V - Working temperature ?45+85°C - Dimensions: 550 x 510 x 25 mm - Weight:
3.36 kg
