16%. Solar thermal power generation ranges from 78% optical efficiency, 60% photothermal efficiency, 30% heat loss and turbine efficiency, meaning the final plant efficiency electric is 16%. Solar thermal power generation refers to the use of large-scale arrays of parabolic or dish-shaped mirrors to collect solar thermal energy, supply steam via heat exchange devices, and combine it with traditional steam turbine generator processes to achieve the goal of electricity generation.
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 standard sunshine (1,000 watts/square meter), the powerThis power of a 1 square meter solar panel is 130 to 180 watts, and the average photoelectric conversion efficiency is 13% to 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.
