Solar electricity know-how

How does a solar electricity system work?

The basic principle of a solar electricity generator is the transformation of solar radiation to electricity with solar cells.

The most common solar cells generally are made out of silicon. Special procedures refine this common mineral. When the sun shines onto the solar cells, an electric field arises and the current begins to flow. Commercially available solar cells can reach an efficiency of up to 18%. They are interconnected and combined into solar modules.

The direct current output from the solar modules can be transformed into AC current and fed into the public grid (grid connected solar electric systems). So called “off grid” or “Island” systems directly utilize the produced electricity or store it in solar battery banks for later use.

A grid connected solar electricity installation with 1 kW power output gives you the gift of annually approx. 800kWh clean electricity and spares the environment of roughly 500 kg carbon dioxide and other pollutants.
