In homes where there is no connection to the main electrical grid, photovoltaic solar energy is the only solution to obtain electricity. With a solar installation we can illuminate the house and use low consuming electrical appliances. SUNCO has developed the Solar Autonomous System, a system whose purpose is to guarantee a supply of electricity, autonomous and independent from the public electrical grid.
