The photovoltaic installation supplies all the energy generated to its own consumption. The difference between demand and production is obtained from the electricity grid. At the moment when there is no solar radiation, the system is exclusively powered by the electrical network.

The new regulatory framework provides for the possibility of compensation or sale of surplus generated in periods when there are no or very small consumption. Alternatively, if the producer does not want to enter the sale, an electronic device -injection inhibitor- prevents the surplus from being discharged into the network.

Yes. By adding batteries to the installation, surpluses can be stored and used when necessary, mainly times of low radiation or at night.
