Solar panel installation on the Cote d'Azur, with English-speaking specialists
A south-facing Riviera roof makes about 50% more solar power than the same roof in northern France, and around 40% more than in southern England. The French rules for using and selling that power are their own, though. So are the permits and the tax breaks. Here's what to know before you talk to an installer.

How it pays
Why do French solar panels only pay if you use the power yourself?
Most home systems in France run on autoconsommation avec vente du surplus. You use what the panels make as they make it. Whatever you don't use goes to the grid, and EDF OA (obligation d'achat) buys it under a 20-year contract.
Since June 2026 that surplus earns 1.1 c EUR/kWh before tax. The one-off prime à l'autoconsommation that used to sweeten the deal was abolished at the same time. Each kWh you use yourself saves the full price you'd pay the grid. Each kWh you export earns almost nothing.
So the question to put to an installer is how much of the output you'll use. Panels pay best alongside loads that run in daylight: a pool pump, a heat pump, an electric car charging at home, or a water heater and washing machine on timers.
A second home is harder. The panels work all year, but nobody is there to use the power for much of it. Size the system around the months you're in residence and what runs while you're away. A battery can move midday surplus into the evening, but it changes the sums and the TVA (see below).
Sizing your system
How much will a solar system generate on the Cote d'Azur?
Here, each kWp of panels on a south-facing roof at a 30-35 degree tilt makes roughly 1,300-1,500 kWh a year. Panels facing east or west make about 15-25% less. They spread their output across the morning and late afternoon, though, which helps if that's when you use power.
A bigger system isn't automatically better. It only helps if you use the extra output, because what you export earns so little. Ask each installer to show expected yearly output for your roof next to your actual use, month by month. Our cost table below gives the output for each common size.
Equipment
Which solar panel brands will Riviera installers quote?
You'll mostly see Q Cells (Hanwha) and Canadian Solar, both widely fitted in France and well supported by French installers. SunPower sits at the premium end. It's worth paying for only when roof space is tight and you need the most output per panel.
The bigger choice is the onduleur, the box that turns panel power into household power. A single central unit (Fronius is a common make) is the cheapest and suits a simple, unshaded roof. SolarEdge and Enphase add electronics behind each panel instead. That costs 1,500-3,000 EUR more, but it keeps one shaded panel from dragging down the rest, and you can see what each panel produces. It earns its cost on a roof with a chimney, a tree or two orientations. Ask the installer which they chose and why.

What does solar panel installation cost on the Côte d'Azur?
These are prices for a fully installed, grid-connected system on an existing roof, with the yearly output a south-facing roof here should give.
Figures are guidelines. Installation costs vary and subsidy rules change.
Confirm current amounts with your installer before signing.
TVA is 5.5% on a system up to 9 kWc on an existing home, if three things are true. The panels meet a low-carbon standard, an energy management system is included, and since 1 March 2026 the installer holds RGE QualiPV. Miss any of them, or go above 9 kWc, and the rate is 20%. That RGE condition is specific to solar; most other renovation work gets its reduced rate without it.
Watch the battery. If one is on the same job as the panels, the whole invoice goes to 20%, panels included. Ask for it to be quoted as a separate job.
There's no grant to set against these prices. MaPrimeRénov' has never covered solar panels that make electricity, so they're not eligible, and the prime à l'autoconsommation ended in June 2026. The solar panel costs guide goes through what moves a quote up or down.
Coming from abroad
What's different about solar panel installation in France?
UK
The Smart Export Guarantee pays a per-kWh rate for everything you export, so a UK system can be sized for export. In France the export rate is 1.1 c EUR/kWh, so that approach fails here. Design the system around what you'll use during the day.
US
There's no net metering in France. Exports aren't credited at the retail rate; EDF OA pays far below it. The return comes from the power you use directly, so expect modest earnings from anything you send to the grid. The permit side is simpler than in many US jurisdictions: a standard roof system needs only a declaration at the mairie.
Germany
The Einspeisevergütung traditionally paid a set rate for exported power. France pays almost nothing for export, so all the value is in self-consumption. German buyers usually have realistic expectations of how panels perform. What changes is how you size the system.
Choosing a contractor
What should you look for in a solar installer on the Cote d'Azur?
Ask for RGE QualiPV by name. An RGE certificate for insulation or heating doesn't cover solar, and without QualiPV you lose the 5.5% TVA rate. Ask to see the certificate and check the expiry date.
The installer should handle the EDF OA application for your surplus contract as part of commissioning. One who leaves it to you, or seems unsure how it works, is a red flag.
The devis should name the panel make and model with its warranty, the equipment that converts the power, and the total system size. It should also give expected yearly output for your roof, the roof work and any scaffolding, the grid connection and the EDF OA application. A single round number with none of this isn't a quote you can compare.
In a protected zone, ask whether the installer has taken a project through the Architecte des Bâtiments de France before. A first-timer will slow things down. Our guide to permits for home energy work in France covers what applies to your property.

Questions
Frequently asked questions about solar panels on the Cote d'Azur
If your question isn't here, send it with your request and we'll answer it directly.
No. The arrêté of 1 June 2026 abolished it, and grid-connection requests filed from 5 June 2026 get nothing. No new premium replaced it. If your system was connected under the old rules, you keep your award and your contract runs its full 20 years. Treat any quote that still counts the premium in its payback as out of date.
Panels on a roof need a déclaration préalable at the mairie, whatever the size. On the ground outside a protected zone, a system under 3 kW and no more than 1.80 m high needs nothing; anything bigger needs a déclaration préalable. In a protected zone the Architecte des Bâtiments de France gets a say, and a ground system of 3 kW or more needs a full permis de construire. Ask the installer who files it.
No. MaPrimeRénov' has never covered photovoltaic panels, so a PV system is not eligible at any income level. For a second home it wouldn't apply anyway, because the grant is for principal residences only. The support that remains for panels is the 5.5% TVA rate.
It goes to the grid, and EDF OA pays 1.1 c EUR/kWh for it (before tax) under a 20-year contract. You pay many times that for each kWh you buy from the grid. Selling everything you generate (vente totale) is no longer offered for home-sized systems. So a kWh you use yourself is worth far more than one you export.
Usually not. If a battery is part of the same supply-and-install job, the tax authority taxes the whole invoice at 20%, panels included. Panels alone can qualify for 5.5%. Ask the installer to quote and invoice the battery as a separate job, and see our battery storage page for whether one makes sense for you.
