Frequently asked questions
What is the ROI of solar panels in France?
Solar panels in France typically pay for themselves in 8-12 years depending on region and self-consumption rate. Southern regions achieve faster payback. With current electricity prices, a 6kWp system can save 800-1,200 euros per year.
What is the EDF OA feed-in tariff rate in 2025?
The EDF Obligation d Achat tariff for surplus solar electricity is around 0.13 euros per kWh for installations under 9 kWp in 2025. Full sale tariffs are lower at 0.10-0.11 euros per kWh.
How much does a solar panel installation cost per kW in France?
A residential solar installation in France costs between 2,000 and 3,000 euros per kWp installed, including equipment, labor, and grid connection. A typical 6 kWp system costs 12,000-18,000 euros before subsidies.
Is home battery storage worth it in France?
At current prices of 5,000-10,000 euros for 10 kWh, home batteries have a payback period of 12-15 years in France, which exceeds most battery warranties. They make more financial sense for off-grid properties.
