Price of an installation for a home

| Type of installation | Guidance Price (2026) |
|---|---|
| Without battery (self-consumption + surplus) | €4,000 – €7,000 |
| With battery (more independence) | €7,000 – €9,500 |
The norm for a detached house is between 3 and 7 kWp of power. A battery usually increases the budget by 30% to 50%.
What does the price depend on?
- Your consumption (how much electricity you use and when).
- The power you need (number of panels).
- Your roof: orientation, tilt, and available space.
- With or without a battery, and the quality of the materials.
How much will you save?
A 5 kWp installation in a home with average consumption (3,500–4,500 kWh per year) saves between €650 and €1,100 per year on the electricity bill. With the rise in electricity prices, those savings tend to grow.

How long to break even?
In most homes, between 6 and 10 years, factoring in compensation for surplus energy. From then on, the energy is practically free for the rest of the panels' lifespan (more than 25 years). If there are subsidies, the amortization is shorter.
What about subsidies?
Depending on the call, self-consumption subsidies can cover a significant part of the cost. At Solariña, we handle the paperwork and find the ones that apply to you, so you only have to worry about saving.
Is it worth it in Galicia?
Yes. Panels produce with light, not just direct sun, so the Galician climate is not the problem many people believe it is. What really decides the profitability is your consumption and your roof — and that can be calculated instantly.
