France's Car-Park Solar Mandate: What Changes on 1 July 2026
If your company operates a large outdoor car park in France, a legal clock is running. Under Article 40 of the loi APER (loi n°2023-175) and its application decree (décret n°2024-1023), the largest car parks must be at least half-covered with energy-producing shade structures — ombrières — and the first hard deadline lands on 1 July 2026.
Who is affected, and when
The obligation is staggered by the size of the outdoor car park:
- Car parks of 10,000 m² or more — deadline 1 July 2026.
- Car parks between 1,500 m² and 10,000 m² — deadline 1 July 2028.
At least 50% of the parking area has to be covered by shade structures that generate energy. The measured surface counts parking spaces and circulation lanes but excludes green areas, storage zones and areas reserved for dangerous-goods vehicles.
Eased in 2025, not repealed
A November 2025 simplification law relaxed how the 50% can be met: owners may now combine photovoltaic ombrières with vegetation and tree shading rather than relying on canopies alone. This matters for accurate planning — but it is a relaxation of the how, not a removal of the obligation. The thresholds and deadlines are unchanged, and photovoltaic generation remains the core of any compliant solution.
The cost of doing nothing
Non-compliance carries an annual penalty until the site is brought into line — up to €20,000 per year for parks under 10,000 m² and up to €40,000 per year for the largest sites. For a facilities or real-estate team, that turns a capital project into a recurring liability the moment the deadline passes.
Turning the obligation into an asset
The smarter way to read the mandate is as a forced entry point into on-site energy. A solar car park is a dual-use surface: it shelters vehicles, generates electricity on land that is already sealed, and — paired with charge points — refuels a fleet during the hours it sits parked. Because midday solar output lines up closely with daytime workplace charging, a large share of the generation can be consumed on site rather than exported at low prices.
The economics reward self-consumption. Adding storage lets a site shift surplus into the evening and shave demand peaks, and it reduces exposure to a grid where connection queues are lengthening across France. In other words, the compliance spend can pay for itself as an energy asset rather than sitting on the balance sheet as a pure cost.
What to check before the deadline
Three things determine whether a site can realistically comply in time: the usable roof geometry of the car park (column grid, circulation lanes, drainage and shading), the grid-connection timeline with Enedis, and how charging and storage are sized against the site's real load profile. Connection lead times are the most common reason projects slip — starting the raccordement early is what keeps a July deadline achievable.
meeco does not operate a French office and does not claim one; our engineering and EPC teams work on French sites from our European hubs, with surveys and meetings held at the project location. If your car park is approaching one of these thresholds, the time to prepare a compliant, self-consumption-led design is now — well before the penalty clock starts.
