Who can apply for INEGA subsidies for residential photovoltaics?

Individuals, property companies, and communities of owners, provided the home is in a non-urban area (rural parishes on the official FEADER list). Homes in urban areas are excluded from this specific program.

Is the INEGA subsidy compatible with the income tax (IRPF) deduction and property tax (IBI) bonuses?

Yes. They are three different and compatible levels: the INEGA subsidy (Regional Government), the IRPF deduction of 20% or 40% (State), and the municipal IBI bonuses (up to 50%) and ICIO (up to 95%), depending on your town hall.

Are batteries covered by the INEGA subsidy?

Lithium batteries are: they add up to an additional €2,000 in subsidy per home. Lead-acid batteries are not eligible.

INEGA Solar Panel Subsidies in 2026

Q: How much money does INEGA provide for installing solar panels?

The current residential program (IN421N/IN421O) covers 50% of the eligible investment, with a maximum of €4,000 per home for panels plus an additional €2,000 if you add a lithium battery. In multi-family or community projects, the maximum is €25,000.

Q: Can I apply for the INEGA subsidy right now?

It depends on the timing: it is a seasonal, competitive call, not a subsidy open all year round. The application period for the 2025-2026 call was from 10/31/2025 to 12/01/2025 and is now closed. The best move is to have your installation prepared so we can notify you as soon as the next one opens.

The Galician regional government (Xunta) subsidy can pay for half of your installation: up to €4,000 per home plus €2,000 for a battery. But there are two fine-print details you must know before counting on it.

The INEGA (Energy Institute of Galicia) subsidies for residential photovoltaics cover 50% of the eligible investment, with a maximum of €4,000 per home for panels and an additional €2,000 if you add a lithium battery. The fine print: the current program is aimed only at non-urban areas (rural parishes) and operates by a seasonal call with limited spots — it is not open all year. Here we tell you exactly what it covers, who can apply, how the calendar works, and how we handle it for you.

In short: 50% of the investment, max. €4,000 per home + €2,000 for a lithium battery (€25,000 in communities of owners), only in non-urban parishes and by an annual call that runs out. Compatible with income tax (IRPF) and property tax (IBI/ICIO) bonuses. Calculate your installation →

How much money does INEGA provide?

The current residential program is the 2025-2026 subsidies for photovoltaic energy projects in the residential sector in non-urban areas (procedure codes IN421N / IN421O), co-financed with European FEADER funds. These are the amounts:

Concept	Amount
Subsidized percentage	50% of the eligible investment
Maximum per home (panels)	€4,000
Extra for lithium battery	+ €2,000 additional
Maximum multi-family / community	€25,000

Lead-acid batteries are not eligible; the extra applies only to lithium batteries.

Who can apply? The important nuance: non-urban areas

Beneficiaries can be individuals, property companies, and communities of owners. But there is a requirement that many people discover too late: this program applies only to non-urban areas — rural parishes included in the official FEADER list. If your home is in an urban center, as of today there is no equivalent open call for you, and it is best not to count on those €4,000 until there is one.

The good part for our area: a large part of the province of A Coruña is exactly that — rural parishes with detached homes. We check for you if your parish is on the list before promising you anything.

When can you apply? Deadlines and real calendar

Here is the second fine print, and we tell you honestly: the INEGA subsidy is not open all year. It is a seasonal and competitive call — limited spots and funds that run out.

2025-2026 Call: the application period was from 10/31/2025 to 12/01/2025 and is now closed.
Next call: as of today there is no new open call for individuals. If the pattern repeats, we expect a new seasonal application window — and whoever arrives with the documentation prepared gets in; whoever starts moving when it opens, usually gets left out.

The right move: don't wait for the deadline to open to start. Prepare the study of your roof and the quote now, and when INEGA opens the window, your application will be one of the first to go out. At Solariña we notify you of the opening and handle the paperwork for you.

Is it compatible with the income tax (IRPF) deduction and IBI?

Yes, and that's the beauty of it: they are three levels of aid that add up. In addition to the INEGA subsidy, you have the IRPF deduction for solar panels in Galicia (20% or 40% of the investment depending on the accredited energy improvement) and the municipal bonuses on property tax (IBI, up to 50% of the quota for several years) and the construction tax (ICIO, up to 95%), which depend on your local council's ordinance.

How we handle it for you

The INEGA paperwork — list of parishes, electronic application, technical report, justification on time — is exactly the kind of bureaucracy that makes people miss out on the subsidy. Our process: we do the study of your roof via satellite for free, we check if your home is in an eligible area, we tell you what subsidies you truly qualify for (INEGA, IRPF, IBI/ICIO) and we submit and justify the application for you when the call opens.
