How Much Do Solar Panels Cost in France in 2025?
Installing solar panels in France has never been more attractive. With rising electricity prices, environmental awareness, and strong government support, French households and businesses are increasingly switching to solar energy. But how much do solar panels actually cost in France in 2025?
This article will help you understand the complete cost breakdown, incentives available, best products on the market, real use cases, and how to purchase a system with maximum return on investment.
Average Solar Panel Installation Cost in France
The average cost of a residential solar panel system in France ranges between 6,500€ and 11,000€ for systems from 3 kWp to 6 kWp, including panels, inverter, mounting, labor, and grid connection. Prices can vary depending on:
- Panel brand and efficiency
- Inverter type (string or microinverter)
- Roof condition and accessibility
- Battery storage inclusion
- Government incentives applied
As of 2025, the typical price per installed watt (Wc) falls between 1.40€ and 1.80€/Wc. Adding battery storage increases the overall cost but offers significant energy autonomy benefits and can qualify for additional subsidies.
Factors That Influence Solar Costs in France
System Size and Consumption Needs
A smaller home that consumes around 3,000 kWh annually might need a 3 kWp system, costing roughly 6,500€. Larger families with annual consumption of 5,000–6,000 kWh will likely require a 6 kWp system, costing around 10,000€ before incentives.
The more self-consumption you achieve, the higher your ROI. Pairing panels with a smart inverter or battery allows you to use more of your own energy and rely less on the grid.
Tax Incentives and Subsidies
France offers several incentives that significantly reduce your out-of-pocket cost:
- MaPrimeRénov’: Grants up to 4,000€ for eligible solar energy improvements
- Reduced VAT (10%) for systems under 3 kWp with certified installers
- Net metering (OA Solaire): Sell surplus energy back to the grid
- Local municipal subsidies in certain regions like Occitanie or Nouvelle-Aquitaine
These programs make solar more affordable and shorten the payback period to 6–9 years for most installations.

Use Cases: Real French Homeowners and Their Solar ROI
In Bordeaux, a 5 kWp system using DualSun FLASH panels and Huawei SUN2000 inverter cost the homeowner 9,800€ before incentives. After applying for MaPrimeRénov’ and reduced VAT, the net cost dropped to 7,200€. Their electricity bill decreased by 68% in the first year.
In Toulouse, a homeowner installed SunPower Maxeon 6 panels with Enphase IQ8 microinverters on a small but complex rooftop. Thanks to high panel efficiency and microinverter optimization, the system produced 15% more than predicted. They began selling surplus energy through OA Solaire within three months.
In Lille, a retired couple combined a Trina Solar 6 kWp setup with Huawei LUNA battery storage. The total system cost was 14,200€, partially offset by a 4,000€ MaPrimeRénov’ grant. Their self-consumption rate rose to 80%, and they now only rely on the grid during peak winter usage.

Frequently Asked Questions
1. What is the payback period for solar panels in France?
Most homeowners recover their investment in 6 to 9 years, depending on system size, incentives used, and self-consumption rate. With battery storage, the period may extend slightly but offers greater autonomy.
2. Are solar panels in France still worth it with net metering changes?
Yes. Even as policies evolve, current OA Solaire tariffs still provide solid returns. Self-consumption remains the key to maximizing ROI, especially when paired with smart inverters or batteries.
3. Can I install solar panels on a secondary residence in France?
Incentives like MaPrimeRénov’ are typically available only for primary residences, but you can still access net metering and VAT reductions. Always check regional rules or consult a certified installer.
