Solar panel ROI in 2026: is it worth it in Málaga?

Yes, installing solar panels in Málaga in 2026 is worth it. But we want to be honest about the numbers. Many websites inflate calculations using 0.22 €/kWh as the electricity price. We use 0.13 €/kWh (real 2026 indexed market) per OMIE OMIE · April 2026 . The figures are more modest, but they are what you’ll really encounter.

Numbers are estimates from public PVGIS, OMIE and RDL 7/2026 sources. Translations may need a fact-check pass — see our calculator for figures using your real consumption.

The real numbers — uninflated

Base scenario: 5 kWp in Málaga capital, no battery, average family consumption of 4,500 kWh/year, instantaneous self-consumption of 40% (realistic with smart appliances).

Data verified directly against PVGIS 5.2 (European Commission, JRC) and the OMIE wholesale market.

With 40% IRPF deduction

If you meet the requirements of DA 51 (energy certificate before/after, ≥30% reduction in non-renewable primary energy — see our honest IRPF guide), regulated by RD-L 7/2026:

With IRPF + IBI (Torremolinos example)

Torremolinos has a 50% IBI bonus for 3 years (verified against Fundación Renovables). If your base IBI is ~€700/year, you save €350/year × 3 years = €1,050 additional:

25-year projection

Panels last at least 25 years (manufacturer performance warranty: 80-87% at year 25). If electricity prices rise 3% annually (European historical average), your savings grow each year:

When it’s NOT worth it

Let’s be honest. There are situations where installing solar is not the best option:

If in doubt, use our solar calculator with real PVGIS data for your specific municipality — it’s the fastest way to know if it’s right for you.

The factor almost no one mentions: future electricity prices

Electricity prices in Spain have risen on average 3-5% annually over the last decade. In 2025 they rose 15.5% per FACUA data. If this trend continues:

Each electricity price increase automatically increases your savings because you produce your own energy at zero cost after recovering the investment. Solar energy is a hedge against energy inflation.

Compared to other investments

The key advantage of solar: the sun rises every day and production is predictable. Versus a stock investment, solar is much more stable. Versus a rental property, solar has no risk of unpaid rent or damages. The only downside is liquidity: you can’t “withdraw” your installation to recover cash quickly.
