The Evolution of Photovoltaics in France
Systems up to 100 kWp with quarterly feed-in tariffs.
Decree S21 of October 6, 2021 : Terms and conditions for purchasing electricity generated by photovoltaic systems installed on buildings, sheds, or shade structures up to 500 kWp.
Replaces S17/S18; main framework since 2021 (amended in 2025). Rates and investment incentives are adjusted quarterly.
- Residential customers: full resale or self-consumption (with or without surplus, investment incentive).
- Businesses: up to 500 kWp on buildings, hangars, or ground-mounted shade structures; for resale or self-consumption with surplus.
- Sale to EDF OA Solaire.
Increase in feed-in tariffs and surplus electricity resale rates, as well as the investment incentive; reduction in the range of power capacities eligible for the open-call program; and implementation of a financial guarantee of €10,000 for projects exceeding 100 kWp.
- The decree is gradually transitioning to the Simplified Request for Proposals (SRP), which will be implemented in September 2025.
- The feed-in tariff for power plants with a capacity of up to 100 kWp will remain unchanged.
The goal is to manage the volume of projects and ensure competitive pricing.
- < 100 kWc : tarif d’achat maintenu, évoluant chaque trimestre.
- 100 to 500 kWp: applications submitted on specific dates, subject to administrative and technical criteria; market-based tariff.
- CRE Application: Accepted = Selected; Rejected = May be resubmitted.
- Payment via an aggregator, with the supplement and bonus covered by EDF OA Solaire (2 contracts).
Request for Proposals (RFP) : > 500 kWp (high-voltage and ground-mounted), subject to CRE regulations, including administrative criteria and ISO 9001 and 14001 standards, to select the most competitive and reliable projects.
VAT reassessment for solar power plants up to 9 kWp in October 2025.
