What Solewa does

Wewise France (commercially also referenced as Solewa) is a French B2B solar energy solutions provider operating as the photovoltaic division of Groupe Butagaz. The company designs, finances, constructs, and maintains photovoltaic installations for professional customers across four primary segments: industry, the tertiary (commercial/service) sector, local authorities (collectivités), and agriculture. Headquartered in Levallois-Perret with 14 to 15 regional agency locations across metropolitan France, Wewise claims more than 20 years of operating history and over 7,000 solar plants in operation, with named customers spanning industrial (Soprema, Breger), retail (E.Leclerc, Super U), agricultural cooperatives (Cavac), energy (Sipenr), and healthcare (Biofarma).

The company's core offering covers six product lines — rooftop photovoltaic installations, ground-mounted solar farms, parking canopies, floating photovoltaics, EV charging stations, and Battery Energy Storage Systems (BESS) — complemented by a full lifecycle service stack including engineering and design, project financing, construction, operations and maintenance, energy valorization (PPA structuring), and aggregation services that pool generation for grid-market participation. Underlying technology is commodity photovoltaic hardware layered with EPC project execution capability, BESS integration, and EV charging infrastructure; no proprietary software, AI/ML capability, or platform IP is documented in the available data.

Wewise generates revenue primarily through project-based B2B solar installations (hardware sales plus EPC services), with pricing not publicly disclosed and contracts structured as custom quotes per project. The company is a wholly-owned subsidiary of Groupe Butagaz, a French energy group, which provides balance-sheet backing and distribution synergies. Wewise has communicated a €200M revenue target for fiscal year 2025 and reports a workforce of 400+ collaborators, alongside a separate 'Wewise Europe' entity suggesting cross-border ambitions beyond the French domestic market.

Direct peers

• Sun'R: French solar IPP and energy aggregator developing rooftop, ground-mounted, and agrivoltaic projects. Comparable as a France-focused mid-market competitor with overlapping solar technology mix and a growing emphasis on storage and aggregation services.
• GreenYellow: French energy services company (Casino group affiliate) providing B2B solar, BESS, and energy efficiency solutions to retail and industrial customers. Strong overlap in vertical segmentation (especially retail/tertiary) and in offering O&M + valorization services alongside installation.
• Photosol: French solar IPP/developer building and operating utility-scale and distributed PV assets for professional clients. Comparable as a France-focused solar developer-EPC with overlapping end-customers and similar project development + asset operation model.
• Urbasolar: French B2B solar EPC and IPP, now part of the Engie group. Operates ground-mounted, rooftop, and floating PV projects across France with comparable scale, customer segments (industry, tertiary, agriculture), and end-to-end service offering — directly comparable to Wewise's core business.
• Tenergie: Independent French solar EPC and developer serving industrial, tertiary, agricultural, and public-sector customers. Operates a comparable end-to-end model (design, financing, construction, O&M) with similar geographic focus on France and overlapping client verticals.
• Voltalia: Listed French renewable IPP/EPC active in solar, wind, and storage across multiple geographies. Directly comparable as a France-rooted B2B solar operator with both project development and O&M/aggregation capabilities serving industrial and public customers.
• Neoen: French-origin independent renewable IPP (now majority-owned by Brookfield) with significant solar, storage, and PPA operations in France. Comparable on the asset-ownership + aggregation + valorization services side, though materially larger in scale.

Broad incumbents

• EDF Renewables: Renewables subsidiary of EDF, developing and operating solar, wind, and storage assets in France and globally. Competes with Wewise for the same French B2B solar RFPs with deeper capital and broader energy-services portfolio.
• Engie Green: Renewables arm of Engie, one of France's largest energy groups. Offers utility-scale solar, wind, storage, and B2B energy services across France — overlapping with Wewise's customer base and service breadth, but at materially larger scale and balance sheet.
• TotalEnergies Renewables: Integrated energy major expanding aggressively into French B2B solar, storage, and EV charging — directly overlapping with Wewise's product portfolio (PV, BESS, EV charging) and target customer segments, with materially greater financial firepower.
