π° How much does a solar installation cost in 2025?
Good news! In 2025, the prices of solar panels have dropped thanks to technological advancements and increased production. But you still have to consider:
| Installed power | Average cost in 2025 (excl. VAT) |
|---|---|
| 3 kWc (small house) | 5,500 to 8,500 β¬ |
| 6 kWc (standard house) | 8,000 to 13,500 β¬ |
| 9 kWc (large house) | 12,500 to 18,000 β¬ |
π‘ Why this drop in prices?
βοΈ More efficient and cheaper panels thanks to new TOPCon and HJT cells π
βοΈ Massive production in Europe and Asia that reduces costs
βοΈ Installation is increasingly simplified thanks to microinverters and optimizers
π The price is dropping, but be careful: the aids are also changing!
π What financial aids are available in 2025?
In 2025, several measures still exist to reduce the installation cost of your solar system.
π 1. The photovoltaic self-consumption bonus (Update 2025)
π° Still active in 2025, it allows you to recover up to 400 β¬ per kWc installed.
π 2. Sale of surplus electricity
With EDF OA and other suppliers, you can sell your surplus at a regulated price.
π‘ Buyback price in 2025: about 0.12 β¬/kWh for installations of less than 9 kWc.
π 3. Reduced VAT at 10%
If your installation is less than 3 kWc, the VAT drops from 20% to 10%, further lowering the final cost.
π 4. Updated local and regional aids
Some communities still offer subsidies in 2025, which can go up to 2,500 β¬!
β³ How long does it take to become profitable in 2025?
This is THE question that comes up all the time: “how many years will my solar installation be profitable?”
π Quick simulation:
- Installation 6 kWc after aids: approximately 7,500 β¬
- Annual savings on the bill: between 1,000 and 1,600 β¬
- Estimated profitability time: 5 to 8 years
π₯ In 2025, profitability is faster than ever!
And after these 5 to 8 years, you continue to save for 20 years or more!
π 5 mistakes that slow down the profitability of your installation
π± Some homeowners take 15 years to make their installation profitable while others do it in 5 years. Why? Here are the mistakes to avoid:
β 1. Incorrectly sizing your installation
If you install too many panels, you lose money. Too few? You keep paying a high bill!
β 2. Poor orientation of the panels
π Ideally facing south, with a 30Β° tilt for optimal yield.
β 3. Not storing the energy
Without a battery, you lose up to 50% of your electricity when you’re not home. A battery can increase your self-consumption to 90%!
β 4. Using a non-certified installer
π¨ Scams and poorly done installations = loss of production and reduced profitability. Always check RGE certifications!
β 5. Not scheduling your devices
Tip: use washing machines, water heaters, electric cars⦠during the day when the sun is shining!
π₯ Testimonial: 5 years after going solar, their bill is β¬0
π’ Julien & Sophie β Installed since 2020
“We invested 10,000 β¬ for a 6 kWc installation in 2020. We received a bonus of 2,500 β¬, and thanks to self-consumption, our annual bill has gone from 1,400 β¬ toβ¦ 150 β¬!“
π Their advice: “Add a battery to store energy at night, we regret not doing it sooner!”
π₯ Is it the right time to switch to solar in 2025?
β With falling prices and rising electricity costs, profitability is faster than ever!
π’ The real risk? Waiting too long and paying even more for your electricity.
