A photovoltaic installation combined with batteries constitutes an innovative system that harnesses solar energy to generate electricity sustainably. The operation of this installation relies on solar panels, typically installed on a roof, which convert sunlight into electricity. This electricity is then stored in batteries, thereby ensuring a continuous power supply even when the sun is not shining.

​

Self-consumption, a key aspect of this system, involves the use of locally produced electricity to meet the energy needs of a residence or business. When electricity demand is low and solar production is high, the surplus is stored in batteries for later use. In cases of low solar production, the batteries provide the necessary electricity, thus ensuring a stable supply. By utilizing energy produced and stored on-site, users reduce their dependence on the traditional electrical grid. This results in savings on electricity bills and a reduced carbon footprint, thereby contributing to the transition towards more sustainable energy sources.
