Why the payback is shorter here

The Costa Blanca has one of the highest numbers of sun hours in Europe — your panels simply generate more here than in Northern Europe. As a result, the payback on this coast usually sits around 5 to 7 years, and with the subsidies and deductions, in as little as 4 to 6.

Where the gains are

Three things speed up your payback:

  • The sun hours — more generation per panel than in the north.
  • The compensación de excedentes — your energy supplier pays for the electricity you send back to the grid (around €0.065/kWh).
  • The subsidies and discounts — the habitual-residence subsidy (up to 40%, max €3,000), the IRPF deduction and up to 50% off the IBI in most municipalities.

Subsidies and tariffs change from year to year and from town to town. At the survey we work out what applies to your home at that moment.

For businesses it’s faster

If you run a business with high daytime usage, the payback sits around 4 to 6 years — shorter still thanks to the libertad de amortización, which lets you write off the whole investment in the first year.

Work it out for your own roof

The figures above are averages for this coast. What it comes to for your home depends on your usage, your roof and your municipality.
