As is the case every quarter, the feed-in tariffs for solar electricity and investment incentives have been revised. Officially published for the period from July 1 to September 30, 2025, these new tariffs apply to photovoltaic installations of less than 500 kWp.
Here is a summary of the main changes you need to know about if you are a professional in the sector or have a solar project:
Vente en totalité pour les installations <100 kWc
Feed-in tariffs fall slightly:
- 9 to 36 kWp: from 12.95 to 12.43 c€/kWh (-4.0%)
- 36 to 100 kWp: from 11.26 to 10.81 c€/kWh (-4.0%)
Prime à l’investissement – Vente en surplus <100 kWc
The premium has also been reduced for installations above 9 kWp:
- 9 to 36 kWp: from €0 .19 to €0.18/Wp (-5.3%)
- 36 to 100 kWp: from €0 .10 to €0.09/Wp (-10%)
- ≤9 kWp: stable at €0.08/Wp
Tarif de rachat du surplus – Vente en surplus <100 kWc
Surplus tariffs remain stable for the smallest installations, but decrease slightly above 9 kWp:
- 0 to 9 kWp: stable at 4.00 c€/kWh
- 9 to 100 kWp: from 7.61 to 7.31 c€/kWh (-3.9%)
Full sale for systems between 100 and 500 kWp
- Base rate: from 9.50 to 8.86 c€/kWh (-6.7%)
📌 Things to remember
The overall trend continues to be a moderate decline in feed-in tariffs and investment incentives, a direct consequence of sector regulation and market dynamics. If you're a developer, installer or project owner, these changes can have an impact on profitability and the trade-offs to be made in choosing the model (self-consumption, sale in full or surplus).
