How a photovoltaic solar system works
A solar electricity system works like a small power plant, feeding the generated solar electricity into the public grid, while the energy supply of a house is assured by the public grid and measured with a demand meter.
The solar future
The sun is readily available worldwide, its energy potential is free, abundant, inexhaustible, and on-hand for billions of years. The sun’s irradiation of just one hour provides already more energy than the whole world population requires in a year.
