Why this estimate is reliable

We use your real roof and real catalogue prices — not blanket regional averages.

Your actual roof, not a regional average

Satellite imagery measures your specific building — usable area, orientation and inclination per roof segment. The result is calibrated to your house, not your postcode.

Spanish climate baked in

Production hours come from PVGIS — the European Commission's open scientific model. Sunshine for your municipality, not Madrid by default.

Real catalogue prices

Equipment costs come from our actual stock with major brands. VAT 21% and certified installation included. No hidden fees on the final quote.

Compatibility-checked

Inverter sizing follows manufacturer rules; phase (single / three) is read from your bill when uploaded; tilted-structure costs are auto-calculated for flat roofs.

Where this estimate is approximate

Prices are accurate. The visual layout is a starting base — small adjustments happen on site.

  • Panel layout is illustrative

    On the result page panels render lying flat across roof segments. On a real installation the engineer optimises tilt and exact placement for the best yearly yield — usually the same panel count, slightly different positions.

  • Very new buildings can be missing

    Satellite coverage in Spain is high, but construction from the last 1-2 years may not appear yet. In that case we fall back to address-based regional averages — still useful, but less precise per-roof.

  • Local rules need a specialist review

    Historic zones, neighbourhood association restrictions or proximity to overhead power lines may affect what's allowed. We handle the paperwork once your exact location is confirmed.

After the calculation

Clear, no-surprises path from your quote to switching on.

  1. Right away

    Your full quote on screen — equipment, installation, total in euros with VAT. Tweak the configuration, save or download the PDF.

  2. Within 24 hours

    A specialist contacts you on WhatsApp or email to answer questions and confirm a few details. No spam calls.

  3. Photos & adjustments

    If we need a closer look at your roof or electrical panel, the specialist asks for a couple of photos over WhatsApp. We refine the design and quote from those — no inconvenient site visit needed.

  4. 2-4 weeks later

    Installation in 1-2 days, grid-connection paperwork filed for you, and your warranty package handed over.

The online quote is non-binding. You only pay after a signed contract with the final price agreed with our specialist.

Frequently asked questions

What does a typical residential system cost?

A 4-7 kW turnkey system in Spain runs €4,500–€7,500 with VAT and installation included. Larger homes with batteries reach €9,000–€15,000 depending on capacity.

How fast does it pay back?

5-8 years in Spain on a grid-connected system at current tariffs. Faster if most of your consumption is daytime, or if you add a battery to cover evenings.

Does it work in winter and on cloudy days?

Yes. Production drops to about 30-40% of summer peak in winter, but solar still contributes year-round. The grid connection covers the gap. What matters for payback is the annual total, which our model already accounts for.

Do I need a permit?

For residential rooftops in Spain it's typically a declaración responsable to your municipality — no full building permit required. We handle the paperwork as part of the installation.

What about VAT and tax breaks?

Reduced VAT of 10% applies to residential installations. The IRPF deduction (up to 40% depending on region) is claimed with your annual tax return — we provide all the certificates you need.
