How much solar panels save per year

Whether solar panels are worth it in Spain depends on three things: how much energy they produce, how much of it you use as it is produced and how much you are credited for what you export to the grid. As a reference, the solar industry put the average home saving in 2025 at about 189 euros per kW installed per year.

What increases the saving

  • Using power during the day: schedule the washing machine, dishwasher, water heater or car charging for sunny hours.
  • Surplus compensation (excedentes): the energy you export to the grid is deducted from your bill.
  • A battery: stores what is left over for the night. In 2025, 61 % of new home installations already included one.
  • Adjusting your contracted power after installing the panels.
  • Combining them with an aerothermal heat pump or an electric car, which turn more of your own production into savings.

Tax advantages

The IRPF income tax deductions for work that improves a home’s energy efficiency, of 20 %, 40 % and 60 % depending on the case, were extended by Royal Decree-law 7/2026. Check with your tax adviser which percentage applies to your installation before counting on it.
