Solar panels

A solar module or photovoltaic module uses the light from the sun to convert it into electrical energy. Solar cells are built into the solar module, which are connected either in series or in parallel.

In order to protect the solar module from external weather conditions, the whole thing is mounted in an aluminum frame and covered with a glass plate.

The photovoltaic module is then connected individually or in a group (the so-called string) in a photovoltaic system.

Each photovoltaic module is characterized by its electrical characteristic (e.g. maximum power, short-circuit current, voltage, etc.) In order to achieve the highest possible efficiency, it is necessary to use solar cells of the same type.
