European Solar Subsidies Guide 2026: Country-by-Country Incentives

European Solar Subsidies Guide 2026

Solar subsidies across Europe are more varied — and in many countries more generous — than most buyers realise. This guide covers the key financial incentives available in each major European market in 2026, from direct grants and tax deductions to feed-in tariffs and low-interest loans.

Germany: KfW Loans + EEG Feed-in Tariff

Germany's subsidy framework is loan-heavy rather than grant-heavy:

• KfW 270 (Erneuerbare Energien – Standard): Low-interest loans (current rate: 0.88–2.15% depending on tenor) for solar + battery systems. No upper limit for businesses. Individual homeowners can borrow up to €150,000.
• EEG Einspeisevergütung (Feed-in Tariff): Systems up to 10 kWp receive approximately 8.2 ct/kWh for exported electricity (2026 Q1 rate). Systems 10–40 kWp receive 7.1 ct/kWh.
• Sonderabschreibung §7g EStG: Businesses can deduct up to 50% of solar system cost in year one via accelerated depreciation — effectively a 25% subsidy for a 50% marginal tax rate payer.
• State programs: Bavaria (PV-Speicher Programm: €500/kWp + €100/kWh storage), Baden-Württemberg (L-Bank loans), and others offer additional support.

Spain: IBI + ICIO Reductions + IRPF Deductions

• IBI reduction: Up to 50% annual property tax reduction for solar-equipped properties. Duration and percentage vary by municipality — check with your local ayuntamiento.
• ICIO exemption: Up to 95% tax reduction on building permits for solar installation in participating municipalities.
• IRPF deduction (15%): 15% personal income tax deduction on solar investments up to €1,000/year for self-consumption systems (extended through 2026).
• IDAE grants (Next Generation EU): Spain's IDAE manages EU Recovery Fund grants for self-consumption. Programs vary by autonomous community — check with the regional energy authority.
• Autoconsumo compensation: Excess solar credited against the electricity bill via the simplified compensation mechanism — not a cash payment but reduces electricity costs.

France: MaPrimeRénov' + Prime à l'Autoconsommation + CEE

• Prime à l'autoconsommation: Capital grant of €130/kWp for systems 3–9 kWp, reducing to €90/kWp for 9–36 kWp systems. Paid by the energy supplier (EDF OA) on grid connection approval.
• TVA réduite (5.5%): 5.5% reduced VAT rate (versus standard 20%) on solar panels and installation for existing residential properties.
• MaPrimeRénov' + solar packages: When combined with insulation or heat pump, solar installation may qualify for additional MaPrimeRénov' support — consult your installer.
• CEE (White Certificates): Certificates d'Économies d'Énergie provide additional financial incentives for energy efficiency measures. Specific solar CEE amounts vary by installer programme.
• EDF OA feed-in tariff: For systems above autoconsommation threshold, EDF OA offers a guaranteed purchase tariff of approximately €0.10–0.13/kWh.

Italy: Superbonus 70% + IRPEF 50%

• Superbonus 70%: 70% tax deduction for comprehensive energy renovation packages (solar + insulation + heat pump) on first homes and condominiums. Spread over 4 years. Subject to ENEA energy improvement requirements.
• IRPEF 50% detrazione: 50% income tax deduction for standalone solar (without full renovation package). Spread over 10 years. Maximum deductible amount: €96,000 per property unit.
• Scambio sul Posto (SSP): Net metering — GSE credits excess solar exported to the grid against electricity import costs. Free to register.
• Incentivi FER 2: Feed-in incentive for systems above a threshold size — replaces the expired Conto Energia. Applies primarily to systems above 20 kWp.
• Credito d'imposta Industria 4.0 / Transizione 5.0: 15–35% business tax credit for energy efficiency investments including solar, under the Transizione 5.0 program effective from 2024.

Netherlands: EIA + SDE++ + Saldering (Phasing Out)

• EIA (Energie-investeringsaftrek): 45.5% energy investment deduction for businesses on qualifying solar investments. Available via the Rijksdienst voor Ondernemend Nederland (RVO).
• SDE++ (large-scale): The main operating support for solar above 15 kWp. Provides a guaranteed income per kWh for 15 years. Round 2025 allocated €12 billion.
• Saldering (net metering) — phasing out: The salderingsregeling allows full offset of solar production against consumption. This ends on 1 January 2027 — urgency to install before the phase-out.
• Warmtefonds (0% loans): National Energy Saving Fund offers 0% interest loans up to €25,000 for homeowners for energy renovations including solar.

United Kingdom: VAT Exemption + SEG

• 0% VAT on residential solar: Extended to April 2027. Saves £500–£1,500 on a typical installation.
• Smart Export Guarantee (SEG): Obligatory payment scheme — suppliers with 150,000+ customers must offer export tariffs. Octopus Outgoing (15p/kWh), E.ON Optimum, and Ovo are competitive options.
• ECO4: Funded solar and insulation for low-income households — check eligibility at gov.uk/energy-company-obligation.
• Enhanced Capital Allowances (ECA): Businesses can deduct 100% of solar costs against taxable profits in year one — effectively the full cost of the system.
• Local authority grants: Several councils (particularly in Scotland and Wales) offer solar grants via LBEG or Nest schemes.

FAQs: European Solar Subsidies

Can I combine multiple subsidies for solar in Europe?

Yes, in most countries. For example, in Italy you can combine IRPEF 50% with Scambio sul Posto. In Germany, KfW loans can be stacked with state-level grants. In France, you can combine the prime à l'autoconsommation with CEE credits. Always confirm current rules with your installer or a local tax adviser.

Do subsidies change frequently?

Yes. Feed-in tariffs are often adjusted quarterly or annually. Tax deduction schemes have eligibility conditions and sunset dates. Always check the current terms with the relevant authority or a certified local installer before planning your system.
