What Wewise does

Wewise is a French provider of solar and energy solutions exclusively for professional clients (industry, commercial/tertiary, local authorities, and agriculture), headquartered in Levallois-Perret and operating through 14 regional agencies across France with a field workforce of more than 400 employees. Its offering is organized around six core photovoltaic product lines — rooftop solar, ground-mounted solar farms, parking canopies, floating photovoltaics, EV charging stations, and battery energy storage systems (BESS) — supported by an integrated service stack spanning in-house design and engineering, project financing, construction, long-term operations and maintenance with remote monitoring, and energy monetization including collective self-consumption (ACC), multi-site PPAs, and energy aggregation. The company reports more than 7,000 solar installations in operation and roughly €200 million in 2025 revenue.

Wewise monetizes through a hybrid model combining one-time project revenue from installation (rooftop, ground-mounted, parking canopies, floating PV, EV charging), managed-service and subscription-style recurring revenue from multi-year O&M contracts and remote monitoring, and Solar-as-a-Service arrangements that lower the capex barrier for clients. Pricing is quote-based on project scope, capacity, and installation type, with multi-year contracts typical for the service components. The go-to-market is enterprise field sales through 14 regional agencies, complemented by content marketing, touring regional events (e.g., the Grand Ouest roadshow with 228 participants), sports sponsorships (Wewise Sailing Team in the Ocean Fifty class), and referral partnerships with financial institutions such as Banque Populaire Val de France.

Wewise is a wholly-owned subsidiary of Butagaz Group, operating alongside sister entities including Certa and Alternative Energy Ireland, through which Wewise is extending its Solar-as-a-Service financing capability into Ireland under a €50 million, five-year investment plan targeting 100 businesses and 50 MW of solar capacity. The business is ISO 9001/14001/45001 certified across 80% of its organizations, holds a 4/5 customer satisfaction score from the Hellowatt platform, and reports a 94% employee pride metric. Customers include E.Leclerc, Soprema, Cavac, Breger, Biofarma, FM Logistic, Haworth, Jabil, and Lindab, among others.
