Photovoltaik, what’s it about?
Photovoltaics describes the conversion of solar energy into electricity.
The French physicist Alexandre Edmond Becquerel discovered as early as 1839, the photoelectric effect. The first industrial application was found in the late 1950s in satellite technology.
For the conversion of solar energy solar cells are used that are connected to so-called solar modules. Solar cells are in most cases made of silicon, which is available in almost unlimited quantity.
From the sun into the socket
For a photovoltaic system, solar panels are interconnected to each of several so-called strings.
The entire system is ideally aligned so that the optimum solar angle of incidence and thus the highest possible energy yield can be achieved over the year. Particularly high efficiencies are achieved tracking systems that adapt by moving the time of day the orientation of the solar cells the current position of the sun.
Inverters convert the DC voltage generated by the solar cells into alternating current. The electricity produced can either be used on site, stored or introduced into the electricity grid.
The overall efficiency of a photovoltaic system depends on various factors. The focus in particular are the optimal alignment, careful and professional installation and the quality and efficiency of the components used.
