The average efficiency of photoelectric conversion is 13% to 18%.
Ordinary solar cells generally produce maximum power when the battery cell voltage reaches 0.4~0.6V.
Under normal conditions In standard sunshine (1000 watts/square meter), the electrical power of a 1 square meter solar panel is 130-180 watts, and the average photoelectric conversion efficiency is 13%-18%.
Based on the average annual sunshine duration of 1,100 to 1,300 hours in Shanghai, under ideal conditions, a 1 square meter solar panel can generate at least 143 degrees of electricity per year.
