The Solar Cell – some figures of merit
At maximum sunshine, the sun delivers about
1000 W/m2 on the earth's surface.
The efficiency of a solar cell is 10% ... 15%.
Hence, a solar panel of 1 m2 delivers an electrical
peak power of 150 W.
The ouput voltage of a solar cell made of silicon
is about 0.6 V, i.e. several solar cells have to be
connected in series to obtain higher output
voltages.
