What Ensol does
Ensol Group SAS is a French residential solar installer and energy solutions provider founded in 2023 and headquartered in Saint-Denis (5 Rue Pleyel, 93200), operating primarily across southern France. The company designs, sells, and installs photovoltaic systems for individual homeowners, exclusively deploying DualSun Flash 500 half-Cut Glass-Glass TOPCon panels (500 Wc, 22.61% efficiency) paired with Enphase microinverters and Huawei central inverters. Its proprietary Energy Management System (EMS) application enables customers to monitor real-time production and consumption, while battery systems enrolled in virtual power plants participate in demand response programs managed by France's transmission system operator RTE. Beyond core solar, Ensol offers solar batteries (purchase or subscription), EV charging stations, and both air-to-water and air-to-air heat pumps as integrated residential electrification products.
Ensol's go-to-market is sales-led, combining a free online solar simulator and digital lead generation with in-home feasibility studies, customized quotes, and certified RGE/QualiPV installation by in-house field teams. Revenue is generated through one-time installation sales priced by system capacity (€7,400-€21,500 for 3-12 kWc systems depending on region), monthly battery subscriptions starting at €30/month on 15-year contracts, leasing schemes for solar panels, and grid surplus resale commissions. Customer acquisition is supported by strong word-of-mouth (20% of clients from referrals), a 5/5 Google rating across 522 reviews, and an NPS of 95 against an industry average of 40. The company has completed approximately 1,500 installations across 1,000+ clients and was named "Meilleur Installateur Photovoltaïque de France 2026" by EUPD Research. Cumulative funding of approximately €14 million has been raised from Otium Capital, Terra Nea, and a BREEGA-led syndicate to scale operations, expand the product portfolio, and extend into adjacent European markets.
