Real calculation of solar savings in Spain, with Málaga data. No inflated promises.
Data
3-person home (6,000 kWh/year)
8 panels of 540 Wp (4.3 kWp):
| Item | Value |
|---|---|
| Annual production | 7,525 kWh |
| Self-consumption (60%) | ~4,500 kWh |
| Surplus (40%) | ~3,000 kWh |
| Annual saving | €1,500 |
| Investment | €4,000 |
| Payback | 2.7 years |
With heat pump + EV (12,000 kWh/year)
15 panels of 540 Wp (8.1 kWp):
| Item | Value |
|---|---|
| Annual production | 14,175 kWh |
| Annual saving | €2,835 |
| Investment | €7,500 |
| Payback | 2.6 years |
With battery
A 5 kWh Pylontech raises self-consumption from 60% to 80%. Extra cost: €2,000-3,000. Payback: 8-10 years. See batteries.

What the budget looks like in each area
The prices here are the ones we apply in Málaga city, Marbella, Estepona, Vélez-Málaga and the Axarquía, and inland too: Cártama, Coín, Alhaurín de la Torre and Alhaurín el Grande. The gap between quotes is rarely the panel brand but the inverter and battery: a Deye hybrid with 10 kWh lands €1,500–€2,500 below the equivalent Huawei LUNA2000. You get both figures in the free solar study, along with your roof's real production.
