Solar incentives across Europe in 2026: country by country

Every European country that has solar incentives structures them differently. VAT rates, export tariffs, net-metering rules, and tax credits vary at every border, and several of the most important levers changed in 2025 and 2026. This guide maps what each country offers today, with every figure tied to our researched data, so you can read your own situation before you talk to an installer.

Use the calculator to run the numbers for your roof. It pulls local climate data from PVGIS and shows you payback, NPV, and IRR with no contact form in the way.

What the incentives actually are

Four levers move the maths, and you need to read all four together.

VAT relief cuts the install price at the till. The UK, Germany, and the Netherlands charge 0% VAT on residential solar, so the quotes you see are already net of it. France charges a reduced 5.5%. We never count VAT relief twice: where the price is already net, we set the capital incentive to zero in our model.

Feed-in or export payments reward the kilowatt-hours you send back to the grid. These rates have collapsed across most of Europe, which shifts the value of solar towards the energy you use yourself rather than the energy you sell.

Grants and tax credits hand back part of the capital cost, sometimes upfront, sometimes spread across years of tax returns.

Net-metering status decides whether your exports net one-for-one against your imports at full retail price, or at some lower wholesale rate. This is the lever disappearing in 2026 and 2027, and it matters more than any single grant.

The 2026 solar incentives table

All figures come from our researched country data, dated mid-2026. Import and export prices are per kWh in local currency. Several of these step down through the year; the dated rows are flagged.

Notes on specific rows

Italy. The 50% deduction is the headline, but you claim it across ten annual IRPEF tax returns and need the tax liability to absorb it. Discounted to today's money at a 4% rate, it is worth roughly 0.39 of the system cost (rather than 0.50). Our model works that way via the incentive_years=10 parameter. Second homes sit closer to 0.28.

Spain. The IRPF energy-efficiency deduction can reach 40% of the cost (base capped €7,500) for installs that lift the home's energy rating to A/B or cut non-renewable primary-energy use by at least 30%; it runs through the end of 2026 (Agencia Tributaria). Because it is conditional, not every install qualifies, so our calculator models a conservative baseline — confirm your own eligibility before counting on the full figure. A municipal IBI rebate may also apply in some places.

Belgium. The entire table row is Flanders, the largest region. Brussels still offers 1-for-1 net metering plus green certificates, which makes it the best deal in Belgium. Wallonia has no net metering for new installs and applies a prosumer tariff. If you are not in Flanders, that row does not describe your situation.

Switzerland. The EVS (Einmalvergütung für kleine Photovoltaikanlagen) is a one-time subsidy for systems under 100 kWp. Canton-level top-ups stack on top. Our model holds CHF 0.277 import and CHF 0.07 export; we describe the mechanism without a modelled incentive rate because cantonal variation is too wide for a single figure.

Ireland. The SEAI grant is structured as €700/kWp for the first 2 kWp and €200/kWp for the next 2 kWp, meaning most homeowners with a 4 kWp or larger system receive the full €1,800. Ireland also applies 0% VAT to the supply and installation of solar panels on private residences (since May 2023), already embedded in the quoted system cost.

Sweden. The skattereduktion (tax credit) for micro-production of exported energy was eliminated on 1 January 2026. The surviving capital lever is the grön teknik installation deduction: 15% of material and labour costs (reduced from 20% in July 2025), capped at SEK 50,000 per person per year (Skatteverket, 2026). The return on a Swedish system now rests primarily on self-consumption and the supplier buyback rate rather than any export incentive.

Austria. The EAG Investitionszuschuss (investment subsidy under the Renewable Energy Expansion Act) offers €150/kWp for residential systems up to 10 kWp in 2026 (the rate tapers for larger systems). Länder (provincial) top-ups stack on top and vary widely. A Made-in-Europe bonus of up to 30% additional subsidy is available if modules, inverters, and storage are all EU-manufactured. The federal figure of €150/kWp on a typical €1,350/kWp system represents roughly 11% of installed cost as an upfront grant.

Portugal. There is no national cash grant for residential solar in Portugal in 2026. SERUP is the DGEG registration portal for self-consumption installations, not a grant programme. The financial levers are: 6% reduced VAT on solar equipment; an IRS income exemption of up to €1,000/year on revenues from surplus energy sales; and an optional municipal IMI (property tax) reduction of up to 25% in participating municipalities. These reduce running costs rather than the capital outlay.

The pattern you should notice

Export rates are retreating almost everywhere. France cut its surplus rate by about 91% in June 2026, to €0.011 (CRE via Hellio, Jun 2026). The Netherlands abolishes net metering outright on 1 January 2027, confirmed by both chambers of parliament (Business.gov.nl, 2025). Italy closed Scambio sul Posto to new installs in September 2025 (ARERA 78/2025). Belgium's Flanders region ended net metering in April 2026 and added a capacity tariff on top. Sweden removed its exported-energy tax credit entirely on 1 January 2026.

Each of these moves shifts the value of solar towards self-consumption: the electricity you generate and use on the spot, which you never pay retail price for. In Germany you import at €0.37 and feed surplus back at €0.0778 (BDEW, 2026), so each kilowatt-hour you use yourself is worth nearly five times one you export. In the Netherlands, a home battery goes from optional to nearly essential once the 2027 cliff arrives.

This is why a flat "solar saves you X" figure from a US-centric site tells you little. The German, Spanish, and Polish maths diverge at the export rate, and the export rate is the part changing fastest.

Where capital grants still help

Direct cash for panels is thinning out across Europe. The UK, Germany, and the Netherlands give you VAT relief and not much else nationally. Scotland still offers an interest-free loan up to £15,000. The UK's Warm Homes Plan (launched January 2026, £15bn) should add low-income grants from around 2027. Italy, Spain, and Poland route their support through the tax system, so the benefit depends on you having tax liability to absorb. France removed its self-consumption premium on 5 June 2026 and now leans entirely on the 5.5% VAT already in your quote.

Ireland stands out in 2026 as one of the few countries with a straightforward upfront cash grant still available: the SEAI's €1,800 maximum for a 4 kWp or larger system is paid directly to the homeowner on completion. Austria offers a meaningful federal investment subsidy of €150/kWp for systems up to 10 kWp, which stacks with provincial schemes. Both are real capital reductions rather than deferred tax benefits.

If you want a market where a grant still moves the needle hard, you look outside Europe. Australia's STC scheme knocks roughly 30% off the gross price at the point of sale (Solar Choice STC guide, 2026), though the scheme deflates annually toward its end date of 2030–2031. Japan stacks national and municipal subsidies to a similar level in the best wards.

How to read your own roof

A table gives you the shape of the thing. It cannot tell you your payback, because that depends on your roof's orientation, your local sunshine, how much electricity you use during daylight, and which supplier tariff you are on. Those four together swing the answer more than any single incentive line above.

That is the gap we built the calculator to close. You enter your location, we pull the local climate data from PVGIS and the average tariffs for your country, and you see honest payback, NPV, and IRR straight away, with no contact form in the way. Then you take a real installer's quote and check it against the numbers.

For the country you actually live in, read the dedicated post: solar incentives in Germany in 2026 or solar incentives in the Netherlands in 2026 carry the full economics, the exact tariff, and the local quirks the table has to flatten. You can also start with is solar worth it in 2026 for a framework that applies everywhere.

Frequently asked questions

Which European country has the best solar incentives in 2026?

Italy and Spain offer the strongest tax-based support. Italy's 50% IRPEF deduction over 10 years is worth roughly 39% of your system cost in present-value terms, and Spain can reach 30–40% for homes qualifying for the energy-efficiency band. Belgium's Brussels region still offers full 1-for-1 net metering plus green certificates, making it the best deal while it lasts.

Is Germany's 0% solar VAT still in place?

Yes. Germany's Nullsteuersatz (0% VAT on residential PV systems up to 30 kWp and their storage) has been in force since January 2023 with no end date set as of June 2026. The saving is already built into installer quotes, so the effective cost in our model is €1,300/kWp net.

What happens to Dutch solar owners when net metering ends in 2027?

From 1 January 2027, the salderingsregeling (1-for-1 net metering) ends. Exported energy moves to the terugleververgoeding, which suppliers set voluntarily and which is expected to fall below €0.01/kWh net after surcharges. Every kilowatt-hour you generate and use yourself still saves the full €0.27 retail rate. A home battery that shifts generation into evening consumption becomes the primary way to protect your return.

Did France cut its solar export tariff in 2026?

Yes. From 5 June 2026, under arrêté S21bis, the surplus export rate fell from €0.127/kWh to €0.011/kWh, a cut of about 91%. The self-consumption premium was also eliminated on the same date. French residential solar now earns its return through self-consumption at the €0.194/kWh retail rate, with grid exports contributing almost nothing.

Can UK homeowners still get solar grants in 2026?

There is no national cash grant for residential solar in England and Wales in 2026. The main lever is 0% VAT on panels and installation, which runs until 31 March 2027. Scotland offers an interest-free loan up to £15,000. The Warm Homes Plan is expected to add low-income grants from around 2027. ECO4 closed to new applications in 2026.
