The conversion efficiency of photovoltaic power generation is very low, crystalline silicon photovoltaic cell conversion efficiency is 13% ~ 17%, amorphous silicon solar cell conversion efficiency is only 6% ~ 8%. 2 affected by climate, long-term snow day, cloudy day, fog and clouds change will affect the photovoltaic power generation, photovoltaic power generation light tower efficiency will reduce a lot.
Due to the solar energy density low, alone with photovoltaic area will be very big, the same power, photovoltaic power generation than wind-light complementary takes up a lot of space is large, the volume too big load increase, is unfavorable to safety.
