The diagram compares two possible ways of generating power for the grid by means of photovoltaics: decentralized use in private households and centralized use in a solar park. In both cases the electric current must be converted into alternating current for feeding into the public grid by using a power inverter. Thanks to modern high-power electronics is it also possible to carry out almost loss-free conversion into medium and high voltages for the 36- and 110-kV network in large solar parks as well.
Incidentally: A solar panel has a power output of 30 – 350 Wp (Watt-peak = output with optimum solar irradiation).
