Quick Answer: How Much Does an Installation Cost?

The average "turnkey" price in Málaga for a detached house ranges from €1,100 to €1,400 per kWp installed.

This translates to:

  • Basic Consumption (3-4 kWp): ~€4,000 - €5,500
  • Medium Consumption (5-6 kWp): ~€6,000 - €7,500
  • High Consumption (8-10 kWp): ~€9,000 - €11,000

Includes: Tier 1 Panels, Inverter, Structure, Legalisation, and Labour. Does not include Batteries.

Estimated Pricing Table (Turnkey)

Installed Power Panels (Approx.) Annual Production* Estimated Price Estimated Annual Savings
3.3 kWp 6-7 panels ~5,200 kWh €4,200 - €4,800 €624–728
5.5 kWp (Standard) 10-12 panels ~8,800 kWh €6,200 - €6,800 €1,056–1,232
8.0 kWp 16-18 panels ~12,800 kWh €8,500 - €9,500 €1,536–1,792

Annual example: stated output × 60–70% direct self-consumption × €0.20/kWh. Exports and incentives are excluded. Output is an illustrative assumption for Málaga, not measured data from your roof. Check orientation, shading and hourly demand.

How Do We Calculate ROI?

We don't believe in empty promises. Our studies are based on real financial engineering:

  1. Direct self-consumption: The example tables assume 60–70% of output. This is not a typical or guaranteed percentage for every home; it must be adjusted to hourly demand and battery use.
  2. Savings and payback: Example annual savings = output × direct-use percentage × €0.20/kWh. Simple payback = investment excluding VAT / annual savings. Exports and incentives are not included.
  3. Complete scenario: The individual study should separate VAT, total investment, exports, financing, maintenance, replacements, degradation and tariff scenarios. Neither a 3% annual price rise nor 0.5% degradation is a universal guarantee.

Tax relief and grants: separate scenarios

Eligibility depends on the property, work and your Spanish tax position. The 2026 self-consumption relief is 10% or 20%, on an annual eligible-cost base capped at €5,000, with installation completed and paid for in 2026, a CIE electrical certificate and other requirements. Separate 20%, 40% or 60% energy-efficiency relief requires certified improvements using before-and-after energy certificates and has its own limits and deadlines. Both routes cannot be combined for the same installation in the same property. Solar panels alone do not guarantee tax relief.
