The PV panel is charged with electric particles from sunlight. Charged particles in the inverter are converted into consumer electricity.

Electricity from the inverter is sent to the grid through a special reverse meter. The electricity bills may fully or partially be deducted by the distribution company, in addition, the consumer may even earn money for the excess electricity generated.

Alternatively, an autonomous electrical system may be arranged without connection to the grid. Due to the high cost of energy-saving technology, this system is commercially ineffective, but justified by the necessary purpose.
