It is an electrical system for the production of electricity by direct conversion of solar radiation, exploiting thephotovoltaic effect. A photovoltaic system is mainly composed of: a set of photovoltaic panels, one or more inverters, i.e. direct current conversion groups produced by the alternating current modules, a special meter used to measure Of the energy produced, and other minor electrical components for the protection and insulation of the system. To date it is also possible to add, both in new plants and in existing plants a series of batteries of accumulation of energy produced by the photovoltaic system, an example Is the Tesla Power Wall of which we are installed certified.
