It is common for a family not to consume all the energy produced by the photovoltaic system, considering that at various times of the day, production exceeds energy consumption. Instead of giving away the surplus, sell it to an electricity supplier.

This process has become even simpler. In order to simplify VAT collection and reduce bureaucratic costs, at the end of 2022, the sale of energy for self-consumption will no longer be subject to VAT, with responsibility falling solely on those who carry out the work. Anyone with an installed capacity of 1MW or less will no longer be required to pay VAT if they sell the surplus.

Is it worth selling the surplus?

Since there are no contractual costs associated with this link to a commercial entity, it is worth selling the surplus. There are plans without loyalty, only with advance notice, which allow the customer to change if they are not satisfied.

What to know before selling the surplus

After installing the photovoltaic panels and registering them with the Directorate-General for Energy, you will need to access your producer's Delivery Point Code, which will appear on your next electricity bill, or you can speed up the process by contacting E-REDES.

You will also need to register your activity with the Tax Authority using the necessary CAE (Economic Activity Code), a simple process that can be done online.

There are fixed tariffs per MWh or tariffs indexed to the SPOT market.
