REGIESOLAIRE

What REGIESOLAIRE does

Regie Solaire is a French turnkey photovoltaic solar installation company founded in 2009 and headquartered in Mignaloux-Beauvoir near Poitiers. The company is a subsidiary of Enerlis, which acts as its parent entity (maison-mère) and provides third-party project financing as well as execution capacity for installations exceeding 500 kWc. Regie Solaire designs, supplies, installs, and maintains photovoltaic systems across rooftop, ground-mounted, parking canopy, agricultural barn, warehouse, and solar hall configurations, using Tier-1 European equipment (PEIMAR, QCELLS, LG, BISOL panels; ABB, SMA inverters; JORISOLAR, DOME SOLAR mounting) with manufacturer warranties of 5–25 years.

The business operates two commercial models: a customer-financed turnkey model (clé en main) and a third-party investment model where Enerlis finances the plant and the customer receives rental income, renovation participation, or discounted electricity rates. Customer segments include agricultural SMBs (the historical core), industrial and logistics enterprises, local authorities and public-sector entities, and social housing providers. Distribution is direct, via a network of six or more agencies across France with 45+ collaborators providing free on-site technical studies, permitting, grid-connection administration with Enedis, and full project management from conception through commissioning. Maintenance and after-sales services (preventive inspections, real-time monitoring, panel and inverter replacement) are offered as recurring revenue.

Since 2020, Regie Solaire has installed 25 MWc across more than 300 photovoltaic plants, with 11.5 MWc commissioned in 2024 alone, and now generates an average annual production of 26.5 GWh — equivalent to the consumption of approximately 5,500 French households. Adjacent offerings include EV charging station (IRVE) installation, battery storage systems, and roof renovation integrated with solar overlay. RGE, RGE QualiPV, RGE Q, and Qualit'Enr certifications (held continuously since 2009) are required for access to French feed-in tariffs and self-consumption premiums on sub-250 kWc installations, and represent a key compliance positioning.
