Solar panels for Costa Blanca and Costa del Sol homes
This coast gets roughly 1,600 to 1,750 kWh a year from every kWp installed — among the best yields in Europe. That turns a €6,000 rooftop into €1,100 to €1,500 of electricity a year, and lifts the energy rating on your EPC at the same time.

What solar costs here, and what it gives back
Installed prices in Spain sit at €1,100 - €1,400 per kWp for residential work. Output below assumes a south-facing roof at around 30° on the Alicante or Málaga coast. Savings assume electricity at €0.22/kWh with 55 - 70% of generation used in the home and the rest exported.

| System | Typical property | Installed cost | Annual output | Annual saving |
|---|---|---|---|---|
| 3 kWp | Apartment or small villa, modest bills | €3,600 - €5,000 | 4,800 - 5,200 kWh | €700 - €950 |
| 5 kWp | Two to three bed villa, no pool | €5,500 - €7,000 | 8,000 - 8,700 kWh | €1,100 - €1,500 |
| 6.5 kWp | Family villa with air conditioning | €7,000 - €9,000 | 10,400 - 11,300 kWh | €1,400 - €1,900 |
| 10 kWp | Large villa with pool and/or heat pump | €11,000 - €14,000 | 16,000 - 17,500 kWh | €2,000 - €2,900 |
Payback typically lands between 5 and 8 years without grants, and faster where you run air conditioning, a pool pump or a heat pump in daylight hours. Panels are normally warranted for 25 years of output, inverters for 10 - 12.
Two worked examples
Villa in Jávea · 6.5 kWp
Four-bed villa, air conditioning in three rooms, pool pump running mornings. €8,200 installed, around 10,800 kWh a year generated, roughly €1,650 off the annual electricity bill. Payback around 5 years.
Townhouse in Estepona · 3.5 kWp
Two-bed townhouse, occupied most of the year, no pool. €4,600 installed, around 5,800 kWh a year, roughly €820 saved annually. Payback around 5.5 years, with a measurable improvement in the EPC energy score.
What affects your figure
How long the whole thing takes
Site visit and design
Roof survey, shading check and 12 months of your bills reviewed so the system is sized on real use, not a sales template.
Written quotation
Fixed price, panel and inverter make and model, expected annual output and a realistic payback figure.
Installation
Most homes here are a single-day job. Larger villas with two roof planes or a long cable route take two.
Boletín and legalisation
Electrical certificate, registration with the regional authority and the surplus agreement with your supplier. Your panels generate from day one.
Surplus credit on your bill
Once compensación de excedentes is active, exported energy appears as a credit on each bill.
