Photovoltaics is a branch of the energy industry, a branch of science that deals with the conversion of solar energy into electricity using the photovoltaic effect/phenomenon. The photovoltaic effect is a reaction that occurs in a semiconductor – the photovoltaic cell (silicon) – when exposed to sunlight. When sunlight reaches the surface of a photovoltaic panel, electrons are excited in the silicon crystals, resulting in the production of direct current. Then, with the help of a voltage converter – inverter, which is also the heart of the entire Photovoltaic system, the direct current (DC) is waved and converted into alternating current (AC) with appropriate parameters. Alternating current is the one, which we can already use in our homes or companies to power electrical devices.

Photovoltaic panels with a mounting system adapted to the type of roofing and location; Photovoltaic inverter with WI-FI communication module or LAN connection and necessary wiring and electrical equipment Energy storage / batteries, which act as emergency power supply for the internal electrical network of the facility and allow for storage of specific amounts of energy, necessary for the operation of electrical loads; Electrical switchgear – the place of connection of the photovoltaic system; Internal grid – home/company electrical grid, which is powered by the electricity produced by the photovoltaic panels. In the most commonly installed photovoltaic systems in Poland, the green energy from the sun is first transferred to storage batteries, then it is further transferred to the home/business grid to power all electrical appliances. Finally, surplus electricity that is not used at any given time is sent to the electricity grid of the operator; Bidirectional electricity meter, installed by the electricity system operator after the installation of the photovoltaic power plant, whose function is to record the amount of energy produced from the photovoltaics and that taken from the grid. The operator shall replace the meter with a bidirectional meter on the basis of an application submitted by the photovoltaic system owner or the installer within 30 days of receipt of a complete set of documents;
