Navigating EU solar grants in 2026 can feel like reading a different rulebook in every country — because it largely is. While EU-level frameworks such as REPowerEU and the Modernisation Fund supply the underlying capital, national governments and regional authorities design the specific schemes homeowners actually interact with. This guide maps the major residential solar support mechanisms across key EU markets and explains what to look for when assessing eligibility and applying.
How EU-Level Funding Flows to Homeowners
No homeowner applies directly to the European Commission for a solar grant. Instead, EU money flows through three principal channels: the Modernisation Fund (drawn from ETS auction revenue and channelled to 13 lower-income member states), the REPowerEU chapter of national recovery plans, and Cohesion Funds administered by regions. Member states convert these allocations into national schemes — grants, tax credits, or subsidised loans — each with its own eligibility conditions. The binding 42.5% renewables target under RED III creates political pressure to keep these schemes funded and accessible.

France: Prime à l'Autoconsommation
France's self-consumption bonus supports systems that export surplus to the grid. Rates are revised quarterly by the CRE regulator. For Q2 2026, residential systems up to 9 kWc receive €80 per kWc — a significant reduction from the €290–390 levels seen in 2022–2023, driven by automatic degression as connection requests surged. The rate has been stable at this level for around five quarters. A separate feed-in tariff from EDF Obligation d'Achat applies to full export systems; rates vary by size and are published on the EDF OA tariff schedule each quarter. Homeowners should lock in their tariff reference year at the time of connection request.
Germany: KfW 270 Renewable Energy Loan
Germany does not offer an outright capital grant for most residential solar installations, but the KfW 270 programme provides low-interest loans covering up to 100% of eligible project costs. Effective interest rates depend on creditworthiness and loan term; the programme covers a wide range, so homeowners should request indicative terms from their bank before assuming a specific rate. A separate 0% VAT measure introduced in January 2023 for systems up to 30 kWp significantly reduces upfront cost. Germany's Einspeisevergütung (feed-in tariff) pays a regulated per-kWh rate for exported or fully fed-in surplus, with the Bundesnetzagentur publishing current rates each year.
Romania: Casa Verde Fotovoltaice
Romania's Casa Verde programme, administered by the Environmental Fund Administration (AFM), provides non-reimbursable grants for residential PV systems. The current 2026 maximum is RON 30,000 (approximately €6,000) for systems that include battery storage, which is now a condition of eligibility. Homeowners can access additional grants for batteries and heat pumps through complementary AFM programmes. Demand has been high; registration windows typically open in tranches and close quickly. Check afm.ro for the current open period.
Poland: Mój Prąd
Poland's Mój Prąd programme is in its sixth edition for 2025–2026. The PV-only grant is PLN 6,000; adding a certified battery storage system increases the maximum to PLN 7,000. A seventh edition is expected in H1 2026. Applications are submitted via the gov.pl portal. The programme has a fixed budget and closes when funds are exhausted, so early applications are advisable.
Italy: Conto Energia Legacy and Current Tax Deductions
Italy's historic Conto Energia feed-in tariff closed to new applicants years ago. In 2025–2026, the main residential incentive is a 50% income tax deduction (Ecobonus) on installation costs, spread over ten years. A 65% rate has applied to certain qualifying energy-efficiency upgrades; homeowners should verify with a qualified tax adviser which rate applies to their specific configuration. The GSE also administers the Ritiro Dedicato buyback mechanism for surplus export.
Key Takeaways
- EU funding flows through national schemes; no homeowner applies directly to Brussels.
- France's prime à l'autoconsommation is now €80/kWc for residential systems up to 9 kWc in Q2 2026 — well below 2022–2023 peak rates.
- Romania's Casa Verde maximum is RON 30,000 (~€6,000) in 2026, with battery storage now a requirement.
- Poland's Mój Prąd 6.0 offers PLN 6,000 for PV-only and PLN 7,000 for PV plus storage.
- Germany's KfW 270 loan and 0% VAT measure are the primary residential incentives; a direct capital grant is not generally available.
Grant rates, budgets, and eligibility windows change regularly. Before instructing an installer, verify the current terms directly with the administering body in your country. Comparisun's tools can help you model payback under the latest available incentives across multiple EU markets.
