On grid photovoltaic system for self-consumption

The photovoltaic systems for self-consumption provide part of the necessary electricity consumption in the residential, commercial or industrial (C&I) application.

The system is connected directly to the existing electrical installation in the building . As a priority is used the energy produced by the photovoltaic system and the rest is provided by the electrical distribution grid.

The PV modules are installed primarily on the roof of the buildings, as well as ground within the surrounding area.
