Solar panel installation in Mougins and the plateau above Cannes

Mougins sits on a plateau around 260m above Cannes, open to the south, with little to shade a roof and around 2,700 hours of sunshine a year. The Alpes-Maritimes gets some of the strongest sunshine in mainland France. A well-installed system on a south-facing roof here produces close to the best a house in continental France can expect.

So the questions in Mougins are which set-up suits the house, and how to avoid the usual planning and installation mistakes.

What pushes the price of solar panels on a Mougins villa up?

The size of the system sets most of the price. Size it to what the house uses in daytime, since surplus power earns little. A pool pump or a car charger justifies more panels, and a house empty half the year needs fewer.

The roof comes next. Barrel tiles take longer to fix to, as the next section explains. A steep or high roof needs scaffolding, and a long cable run down to the fuse board adds labour. A battery takes the whole invoice to 20% TVA (French VAT), so ask for the price with and without one.

East or west-facing roofs still do well here. They produce somewhat less than a south-facing roof, but the total is still good with this much sun. Get two written quotes for the same size of system, each naming the panels, the inverter, the fixing system and the TVA rate. The solar panel costs guide goes into more detail.

How do Mougins barrel tile roofs affect a solar installation?

Most traditional villas around Mougins have Provençal barrel tiles (tuiles canal or tuiles romanes). Installers here fit panels on them routinely, using fixing systems made for barrel tiles that keep the tile pattern intact. The work takes longer than on a flat or interlocking-tile roof and adds a little to the cost.

Ask the installer to show you barrel-tile roofs they've already done. Ask for a waterproofing warranty on the fixing system before you sign.

Do you need planning permission for solar panels in Mougins?

For most houses outside the old village, you file a déclaration préalable (a prior declaration) with the Mougins mairie (town hall). Installers usually prepare it as part of the project.

In or next to the old village, or in a protected heritage zone, the Architectes des Bâtiments de France (ABF) must give an opinion before the panels go up. The mairie's planning office can check your address against the PLU and the heritage zones. Ask early, before you spend time on designs and quotes.

If the villa is part of a copropriété, the co-owners must approve the panels by a vote at the general meeting, which the syndic (the building's managing agent) organises.

What grants and tax rates apply to solar panels in Mougins?

For solar panels that make electricity (photovoltaic, or PV), the national rules are:

• MaPrimeRénov' (the state renovation grant): solar PV panels have never been covered and are not eligible. A solar water heater (CESI) qualified on its own until 1 September 2026; it's now funded only inside a full rénovation d'ampleur project. The solar water heating page covers this.
• Prime à l'autoconsommation: abolished in June 2026 and not replaced. Connection requests filed from 5 June 2026 get nothing.
• TVA at 5.5%: for systems up to 9 kWc (kilowatt-peak, the panels' rated power) on an existing home, with low-carbon panels, an energy management system and an RGE QualiPV installer (QualiPV is the state's approved-installer label for solar panels). Miss any condition and the rate is 20%. The old 10% rate ended in January 2026. Ask for the rate to be stated on the devis (written quote).
• CEE (energy-supplier grants): no CEE payment covers panels that only make electricity. CEE money is available for solar water heating.

Should a Mougins villa use its solar power or sell it?

Home systems now run on autoconsommation: you use what you generate and sell the surplus to EDF OA (EDF's buyer of surplus solar power). Selling everything (vente totale) is no longer offered for home-sized systems. The surplus earns 1.1 c EUR per kWh on a 20-year contract, while grid power costs you far more. So the savings come from using your own power.

Houses with a pool, an electric car charger or steady year-round use get the best return, because they use more of what the roof makes. A battery can shift midday power into the evening; the battery storage page covers the options and the TVA catch.
