Turn Obligation into Opportunity (and to comply with regulations)
Article 40 of Law 2023-175, concerning parking lots larger than 1500 m², obliges operators to equip them with carports integrating a renewable energy process over at least 50% of their surface. As of July 1, 2026, parking lots not managed under concession or public service delegation, larger than 10,000 m², will all be affected by this article of the APER Law. By July 1, 2028, all other parking lots not managed under concession or public service delegation, between 1500 m² and 10,000 m², must also comply.
Article 43 of Law 2023-175, concerning buildings, obliges operators owning buildings and/or covered parking lots of at least 500 m² to integrate a renewable energy process or vegetation that uses potable water only as a supplement to collected water.
Regulatory compliance enables short-circuit use of green electricity. The APER Law (2023-175) facilitates and encourages various stakeholders to implement collective and individual self-consumption operations in compliance with Articles L.315-1 and L.315-2 of the CCH. As such, self-consumption will allow you to reduce your SCOPE 2 by decreasing your electricity energy bill. The use of renewable energy from photovoltaic sources also provides a positive impact on SCOPE 1 if it replaces the use of fossil fuels (Article 27 of the APER Law).
For 20 years to reduce your dependence on the electricity market while improving parking comfort for customers and employees. Carports, by definition, protect users and their vehicles from sun, rain, and hail. They are also equipped with an LED lighting system, ensuring comfortable brightness.

A Question? We Answer It
Self-consumption involves consuming locally the renewable electricity produced by your own photovoltaic installation.
- Individual self-consumption: The electricity produced on your site is directly injected into your building. It powers your on-site equipment in real-time without passing through the public distribution network.
- Collective self-consumption: It allows for the exchange and sharing of electricity between one or more production sites and several consumers (buildings in the same activity zone, municipal sites, etc.). The shared energy then uses the public distribution network to be distributed to participants.
Good to know: These two models combine perfectly. You can prioritize consuming the electricity produced on your site, then share any surplus production with others.
As soon as it is commissioned, your photovoltaic panels generate electricity that immediately powers your site’s electrical appliances.
- During the day / sunny periods: Your site primarily consumes the free solar energy it produces.
- In case of additional need: If your consumption exceeds the instantaneous production capacity (or at night), the public electricity grid automatically takes over to ensure continuous power supply without interruption.
This system allows you to significantly reduce your energy bills and decrease your carbon footprint while maintaining total supply security.
Individual self-consumption allows for a very significant partial autonomy (by greatly reducing your dependence on the electricity grid and energy price fluctuations). However, achieving 100% autonomy (self-sufficiency) remains a technical and economic challenge for most professional sites:
- Solar production varies throughout the day and depends on seasons as well as weather conditions.
- Your electricity needs do not always perfectly coincide with solar production peaks.
To maximize your level of autonomy, it is possible to optimize the management of your consumption or combine a battery storage system.
Collective self-consumption is subject to geographical proximity rules between project members:
- Standard scope (extended collective self-consumption): The maximum distance between the two furthest participants is set by default at 2 km.
- Derogations for peri-urban and rural areas:
- Special case of Fire and Rescue Services (SIS): When a fire station or an SIS establishment participates in the project, the scope is automatically extended to 20 km, without the need for a prior derogation request.
