Solar panels and improvements that add value to your home on the Costa Daurada
With more than 300 days of sun a year, solar self-consumption cuts bills, improves the energy certificate and increases your home's value.

The Mediterranean climate — over 300 days of sun a year in the Ebro Delta — makes solar self-consumption one of the most profitable improvements for a home. Beyond saving, it adds value to the house.
Real savings on your bill
A well-sized photovoltaic system covers much of the home's electricity use, especially in country houses and villas with roof space. In a second home by the sea, with a pool and air conditioning, the savings are particularly noticeable.
Rebates and incentives
Many town halls apply property-tax (IBI) rebates to homes with solar panels, and there are grants and tax advantages for self-consumption installations. Conditions change by municipality and year, so it's worth checking case by case; we'll guide you on what currently applies in the area.
A better energy certificate, more value
Solar panels and other efficiency improvements (insulation, aerothermal systems, windows) improve the home's energy certificate. A more efficient house not only spends less: it sells better and at a better price.
Which improvements add the most value
- Solar self-consumption and, where appropriate, a battery.
- Efficient climate control (aerothermal, heat pump).
- Quality insulation and windows.
- On rural estates: a well, efficient irrigation and your own water treatment.
We advise you on which improvements make sense for each home and which ones genuinely increase the value of your investment.
