A self-consumption photovoltaic facility for a house or a business is very simple, it does not require batteries and it does not cause noises or emit fumes. These kinds of installations have a minimum maintenance, and the manufacturer assures the plaques for 25 years. The energy produced by the solar panels is directly consumed and when the panels cannot ensure enough energy, due to the lack of solar radiation, the facility can continue working using electricity from the local energy company.
