The short answer
For a home on the Costa del Sol, expect roughly €4,200 to €4,600 for a small system, €5,100 to €6,500 for a typical medium system and €6,700 to €9,400 for a larger one, VAT included and before any battery. Roof access, equipment, electrical work and storage move the final figure.
Typical installed prices in Spain, 2026
| System | Typical price | Usually suits |
|---|---|---|
| Small, around 2–3 kWp | €4,200–€4,600 | Lower-use homes, apartments, limited roof space |
| Medium, around 3–5 kWp | €5,100–€6,500 | Most permanently occupied homes |
| Larger, around 5–8 kWp | €6,700–€9,400 | Villas with pools, cooling and several daytime loads |
Ranges based on Spanish residential prices published in 2026, VAT included. They are a guide, not a quotation. Large villas, commercial roofs, batteries and backup are priced separately.
What is in the price
Our quotes cover the whole job: panels, inverter or microinverters, mounting designed for your roof, DC and AC protection, cabling, monitoring, installation, the electrical certificate and the registration paperwork. The fixed scope is written down so nothing appears later.
What makes a quote go up
- Roof access. Scaffolding, high or steep roofs and roofs reached through the house add time.
- Several roof planes. More layout work, more mounting and often microinverters.
- Long cable runs. Common in villas where the plant room is far from the roof.
- Electrical work. An old consumer unit or an upgraded supply.
- Roof repairs. Broken tiles or a worn flat-roof membrane should be fixed before panels go on.
What a battery adds
Battery prices depend on usable capacity, the inverter and whether you want backup. As a rough guide, adding storage to a home system typically adds several thousand euros. We show the battery as a separate line so you can see what it costs and what it saves. See battery storage.
Grants and tax relief
Some Andalusian municipalities offer IBI property-tax reductions for installing solar, and the rules change from year to year. We tell you what applies to your town at the time of quoting.
Getting an accurate price
Send us twelve months of bills, a few roof photos and a list of big loads such as pools, air conditioning and electric cars. We give you a first estimate, then a fixed quote after the survey.
Questions we are often asked
Can I get a price without a survey?
Yes, an estimate. The fixed price follows the survey, once we have seen the roof, access and fuse board.
Why do quotes for the same house vary so much?
Different system sizes, equipment, mounting, warranties and paperwork scope. Compare the full written specification, not just the total.
Does a battery double the price?
No fixed rule. It depends on capacity, inverter and backup.
Is VAT included in your prices?
Yes, the ranges on this page include VAT.
