They come from SolarPlan's market data (installed prices, electricity tariffs, data as of 28 September 2026) and long-term satellite irradiation averages. Your own plan uses your roof, your bill and the subsidies at your address. ## Prices by size and type | Configuration | Price | Production a year | | --- | --- | --- | | [3 kW, no battery](https://solarplan.app/solar/spain/system/3-kw) | €4,300–5,200 | 4,970 kWh | | [4 kW, no battery](https://solarplan.app/solar/spain/system/4-kw) | €5,100–6,100 | 6,630 kWh | | [5 kW, no battery](https://solarplan.app/solar/spain/system/5-kw) | €5,900–7,100 | 8,290 kWh | | [5 kW + 10 kWh battery](https://solarplan.app/solar/spain/system/5-kw-battery) | €11,600–13,900 | 8,290 kWh | | [6 kW, no battery](https://solarplan.app/solar/spain/system/6-kw) | €6,700–8,000 | 9,940 kWh | | [5 kW + 10 kWh battery · EPS](https://solarplan.app/solar/spain/system/battery-backup) | €11,600–13,900 | 8,290 kWh | ## Key figures — Spain _Updated 28 September 2026_ - Home solar system without a battery: 3 kW €4,300–5,200; 4 kW €5,100–6,100; 5 kW €5,900–7,100; 6 kW €6,700–8,000 (installed, VAT included). - With a battery: 5 kWp + 10 kWh €11,600–13,900 (VAT included). - Price per installed watt: €1.21–1.57 (mid of the range, by size). - Sun yield: 1,557–1,712 kWh per kWp a year (Barcelona – Seville). - Payback of a 5 kWp system at 6,600 kWh a year: about 9 years, without subsidies. - Electricity price used (PVPC average): €0.18 per kWh. - National IRPF deduction: 40% of the cost, up to €3,000 (works finished in 2026, with energy certificates). ## Regions with their own programmes - [Andalusia](https://solarplan.app/solar/spain/andalusia) - [Aragon](https://solarplan.app/solar/spain/aragon) - [Balearic Islands](https://solarplan.app/solar/spain/balearic-islands) - [Basque Country](https://solarplan.app/solar/spain/basque-country) - [Castile and León](https://solarplan.app/solar/spain/castile-and-leon) - [Catalonia](https://solarplan.app/solar/spain/catalonia) - [Community of Madrid](https://solarplan.app/solar/spain/madrid) - [Region of Murcia](https://solarplan.app/solar/spain/murcia) - [Valencian Community](https://solarplan.app/solar/spain/valencian-community) ## National programmes Checked against the official source of each rule.

Yes: 2 programmes apply to homes in Spain, including Income-tax (IRPF) deduction for energy-efficiency works — 40%; Income-tax (IRPF) deduction for renewable self-consumption in 2026 — 10%. ### How much do solar panels cost in Spain? A home system of 3–6 kWp typically costs €4,300–8,000 installed, VAT included, before subsidies. ### How much electricity do solar panels produce in Spain? About 1,657 kWh per installed kWp a year with panels facing south at 34°, so a 3 kWp system produces about 4,970 kWh a year. ### How long do solar panels take to pay for themselves in Spain? For a home using 4,000 kWh a year, a 3 kWp system pays for itself in 12 years before subsidies. Subsidies shorten it. ### Can I finance solar panels in Spain? Banks and installers offer their own loans. SolarPlan lists only loans with published terms, and none is listed for Spain yet.
