A 3 kWp installation costs between €6,000-9,000 including VAT, a 6 kWp between €10,000-15,000, and a 9 kWp between €15,000-22,000. Prices vary by panel type, inverter, and installer.

No. It is abolished for any installation whose complete grid-connection application is filed on or after 5 June 2026: the order of 1 June 2026 repeals article 9 of the order of 6 October 2021, which carried it. Files whose complete application predates that day keep the rate and the premium in force when they were filed, for the twenty years of the contract — not by virtue of the order, which is silent on the point, but under article R. 314-12-1 of the French energy code, which shields earlier complete applications from any revision of purchase terms. If a quote still promises you a premium, it rests on an obsolete schedule.

The north receives 1,000 to 1,100 kWh/kWp/year against 1,400 to 1,450 in the south, so sunlight does matter. But since 5 June 2026 it is no longer the deciding factor: with surplus worth only 1.1 c€/kWh, your self-consumption rate settles profitability long before your latitude does. A household that uses a lot of power during the day in Lille is better placed than a second home in Nice.

Currently, batteries are rarely profitable due to their high cost (€3,000-8,000). They make sense if you want energy independence or have very high evening consumption. Battery ROI is typically 12-18 years.

In France, solar panels compensate their manufacturing CO2 in about 2-3 years. Over 25 years, they avoid approximately 1-2 tonnes of CO2 per kWp, despite France's already low-carbon electricity mix.

Yes! With a 6-9 kWp installation, you can cover 30-50% of an EV's annual charging needs with solar energy. This saves €500-1,000/year compared to grid charging and significantly more vs fuel costs.

Installations ≤3 kWp connected to the public grid are tax-exempt. Above 3 kWp, revenues are taxed under Micro-BIC (50% allowance) or real regime, plus 17.2% social contributions.
