What CAPSOLEIL does
Cap Soleil Energie (CSE) is a French renewable energy installation company founded in 2013 and headquartered in Tremblay-en-France, Île-de-France. The company designs, sells, and installs residential and small-commercial renewable energy systems, with a core offering in silicon-based photovoltaic solar panels, complemented by air-to-air and air-to-water heat pumps and thermodynamic water heaters. Its technical stack relies on conventional PV modules paired with per-panel micro-inverters, solar battery storage, controlled mechanical ventilation (VMC), and a proprietary domotics energy management device (FHE) that monitors production and optimizes self-consumption. The company also operates an online photovoltaic simulator that estimates the impact of a 3 kWc installation based on geography, roof orientation, and sunlight exposure.
Cap Soleil Energie is structured as a privately held SARL with no disclosed external institutional investors, and is led by Hossem Rahmouni (Directeur de la publication). It operates with a lean team of approximately 17 employees. The business model is hardware-sales-driven and project-based: revenue is generated primarily through one-time installation fees for PV, heat pump, and thermodynamic water heater projects, supplemented by post-installation services (monitoring app, after-sales support, maintenance visits) and facilitation of surplus electricity resale to EDF OA at the regulated tariff (€0.13/kWh as of December 2023). Pricing is quote-based rather than list-based, with free custom quotes offered across all three product lines and administrative assistance provided for government subsidies such as MaPrimeRénov'.
The go-to-market is direct-to-consumer for residential homeowners across France, supported by a content marketing engine (a 20+ article blog on renewable energy topics), an active social media presence on Facebook, LinkedIn, and Instagram, and earned media coverage in Le Point, Marie Claire, BFMTV, and CNews. The company holds three RGE certifications (general RGE, RGE PV, and RGE PAC), which are mandatory for customers to access French energy subsidies, and has completed 2,400+ PV installations, 1,089+ heat pump installations, and 1,800+ thermodynamic water heater installations since inception, for a cumulative base of 3,640+ clients. Official equipment partnerships with Airwell, Panasonic, and Philips anchor the heat pump and smart home offering, and the company is planning to expand B2B partnerships with local professionals in 2024 alongside its existing field-sales-assisted D2C motion.
