Maximise the sun, minimise the bill.

At the limit, your energy cost can be zero. Solar systems for houses and owner-occupied buildings, installed by engineers who explain.

Why now

Energy prices have stopped being predictable

Producing your own electricity gives you back control: you consume what you produce, store the surplus, and depend less on the grid and its price swings.

Self-consumption is no longer a bet — it's a sound financial decision, with mature technology and a clear payback. The question is no longer "if" but "when" and "with whom".

FAQ

Residential FAQ

How much does it cost to install panels with a battery in a house, and what's the payback?

A typical residential system runs from €3,900 (3 kWp) to €6,400 (8 kWp), before storage. With a battery, the investment increases according to the desired capacity. Payback typically occurs in 6 to 8 years — and every proposal we present includes a payback calculation specific to your case.

Do I need a permit from the local council or E-REDES?

Most residential self-consumption installations fall under a simplified registration regime with DGEG and E-REDES, with no council licensing required. We handle all the paperwork for you.

What space is needed for the battery and the inverter?

The inverter and battery take up little space — usually a wall in a garage, storage room or technical area, ventilated and away from extreme temperatures. The entire installation complies with current electrical safety standards.

Does the system guarantee savings in winter?

Yes. The system is sized for your annual consumption profile. Production is lower in winter, but the battery stores the daily surplus and the grid connection covers the rest.

Am I required to switch energy supplier?

No. Self-consumption is compatible with any supplier. You remain free to choose or change tariff whenever you like.
