Solar panels in Galicia with no investment or risk

Why Galicia is a great province for solar panels

Galicia has less sun than the south (≈ 1,930 h/year in Santiago per AEMET) but an intensive B2B fabric where industrial PV has solid ROI. Four clusters stand out: canning and fishing industry of Rías Baixas (Vigo, Bueu, Cangas, Marín), forestry and cellulose industry of Pontevedra and Lugo, Vigo automotive and dairy industry of A Coruña and Lugo (Galicia is Spain's second largest dairy producer).

Satellite data from PVGIS (European Commission) confirms for Galicia an annual global irradiation on a 35° south-tilted plane of ≈ 1,340 kWh/m² per year, with a specific yield of ≈ 1,220 kWh per installed kWp per year using standard 14 % losses. For comparison, Galicia records ≈ 1,930 sunshine hours per year according to the AEMET Climatological Normals (1981–2010 period).

How much a solar installation produces in Galicia

Installed capacity	Estimated annual yield	Covers the consumption of…
3 kWp	≈ 3,660 kWh / year	Home, 2–3 people
5 kWp	≈ 6,100 kWh / year	Average home with HVAC
8 kWp	≈ 9,760 kWh / year	Detached house with pool or EV
15 kWp	≈ 18,300 kWh / year	SME, retail or small industry
100 kWp	≈ 122,000 kWh / year	Industrial warehouse, oil mill, mid-size hotel

The average Spanish household consumes 3,487 kWh per year according to IDAE (SPAHOUSEC III study), so even a small installation comfortably covers domestic consumption and surplus is offset on the bill under Royal Decree 244/2019.

The Galicia case: canning, Vigo automotive and dairy

The canning and fishing industry of Rías Baixas (Vigo, Bueu, Cangas do Morrazo, Marín, A Illa de Arousa) is one of the world's largest clusters: Vigo is the first European fishing port. Canning plants (tuna, mussel, sardine, anchovy), cold chambers and handling centres operate with high electrical consumption in season. 200-500 kWp PV plants on roof fit with consumption curve.

The Vigo automotive cluster is Spain's second and groups the large vehicle factory in southern Pontevedra + dozens of auxiliary suppliers in O Porriño, Salceda, Mos. Giant industrial roofs and 24/7 operation — MW-scale self-consumption + corporate automotive decarbonisation.

Forestry and cellulose industry (Pontevedra Marín, Lousame, Friol) operates pulp, paper and derivative factories with continuous consumption. Wide industrial roofs and sustained consumption — 500 kWp to 2 MW PV as usual solution.

Galician dairy industry is Spain's second (after Asturias) and concentrates plants in A Coruña, Lugo and Pontevedra. Dairy plants, cheese industry (PDO Arzúa-Ulloa, Tetilla, San Simón), butter. PV + heat pump combination for processing climate control.

How much it costs to install solar panels in Galicia in 2026

With AUREQIS, upfront cost is €0. The model is renting: we finance, install, legalise and maintain the entire system in exchange for a fixed monthly fee calibrated to be equal to or lower than the fixed part of your current electricity bill.

If you wanted to buy the system outright without renting, market ranges for a turnkey installation in Galicia and the province are:

How much you can save with solar panels in Galicia

Average Spanish household electricity spend was €47.80 per month in Q2 2024 (CNMC Households Panel), with an average household price of €0.24/kWh including taxes in H2 2024 (CNMC retail supervision).

In Galicia, a 5 kWp installation produces about 6,100 kWh per year. With a consumption pattern aligned with sunshine hours (appliances, HVAC, hot water), self-consumption covers virtually all annual residential electricity use; surplus is offset on the bill under RD 244/2019. Typical net savings are between 50 % and 70 % of annual cost for an average home.

Grants and rebates in Galicia 2025–2026

• Municipal IBI (property tax) rebate. Galician councils (A Coruña, Vigo, Ourense, Lugo, Santiago, Pontevedra) may apply discretionary IBI rebates for solar self-consumption under art. 74.5 LRHL. The Xunta de Galicia also manages proper incentives via INEGA (Galician Energy Institute). AUREQIS does not process these directly — we put you in touch with an external specialist advisor.
• ICIO works tax rebate. Town councils may apply rebates of up to 95 % on the Construction, Installations and Works Tax under art. 103.2.b of the Local Treasury Law.
• INEA Programme (Junta de Andalucía). Energy efficiency incentives managed by the Andalusian Energy Agency (Order of 24 April 2025, BOJA). →
• RD 477/2021 — National self-consumption programme. In force with an execution deadline of 30 June 2026. BOE.
• IRPF (income tax) deduction (RDL 19/2021). Allows recovery of 20–60 % of cost depending on the works and the certified energy improvement. Agencia Tributaria.

Important: AUREQIS does not directly handle the documentation processing for these grants and rebates — our focus is design, installation, technical legalisation and maintenance. We put you in touch with a trusted external specialist who handles the application and follow-up that applies to your case.

What the installation process looks like

1. Free energy study. We analyse your bill, your roof and your consumption pattern. We present a proposal with a fixed monthly fee and a 25-year savings plan.
2. Technical legalisation. Technical project, declaration, connection with the utility and self-consumption registry with the regional government. We handle everything.
3. Installation. 1–3 days for a home, 1–3 weeks for industry. In-house technicians.
4. Commissioning and monitoring. App for real-time production and consumption.
5. Maintenance throughout the contract. Cleaning, inverter inspection, insurance and technical support included.

Technology and warranties

Bloomberg Tier 1 panels (Jinko, LONGi, Trina, JA Solar, Canadian Solar) with efficiencies above 21 % and linear performance warranty ≥ 84 % at 25 years. Huawei, SMA, Fronius or Solis inverters with Wi-Fi monitoring. Anodised aluminium structures sized for warm climate and coastal environment where applicable (IEC 61701 certification against salt mist).

For industry we can integrate electrical backup systems and combine PV with heat pumps to multiply HVAC savings.

Frequently asked questions about solar panels in Galicia

• 01 Does solar self-consumption make sense in Galicia with so much rain?

  For industry and B2B with continuous consumption, yes — ROI is slower than in the south (10-14 years outright vs 6-8 in Andalusia) but still positive, especially with renting that eliminates the initial investment barrier. The key is that PV does not need "bright sun" but light: even on cloudy days it produces 20-40 % of its nominal.

• 02 How much does a solar installation produce in Galicia?

  Per PVGIS, a PV installation in Galicia south-facing at 30° tilt produces about 1,220 kWh per installed kWp per year (Santiago, A Coruña). In the Ourense interior production rises slightly (≈ 1,280 kWh/kWp/year due to less Atlantic cloud component). A 5 kWp home generates ≈ 6,100 kWh annually.

• 03 For a Rías Baixas canning factory, what sizing makes sense?

  Canning factories in Vigo, Bueu, Cangas and Marín operate concentrated season (summer-autumn for tunas, spring for sardine, year-round for mussel) with peak consumption from cold chambers, sterilisation autoclaves and packaging lines. 2,000-6,000 m² warehouse roofs allow 200-500 kWp plants.

• 04 Do you cover Galicia if your offices are in Andalusia?

  Yes. Galicia is 9-10 h by road from Sevilla; for each project we deploy a dedicated technical team for the entire works execution.

• 05 For forestry and cellulose industry, does it fit well?

  Yes. Pulp, paper and forestry derivative factories (Pontevedra Marín, Lousame) operate with sustained continuous consumption and very wide industrial roofs (often 10,000+ m²). 500 kWp to 2 MW PV plants are viable.

• 06 Who processes the IBI rebate and INEGA aid?

  AUREQIS handles design, installation, technical legalisation and maintenance. Documentation processing for municipal rebates, regional aid via INEGA or national (RD 477/2021, IRPF deduction) is not done by us directly — we put you in touch with an external specialist advisor.
