What Le Triangle Group does
Le Triangle Group (legal entity: Groupe Le Triangle) is a privately held French industrial group headquartered in Morée, Loir-et-Cher, founded by Gilles Deshayes in 1990. The company designs, manufactures, and installs photovoltaic (PV) solar solutions, positioning itself as a vertically integrated "rare industrial manufacturer" in a sector dominated by EPCs and integrators. It operates through eight wholly-owned subsidiaries that cover the full solar value chain from design and metal-structure fabrication to installation and ongoing maintenance: Triangle Élevage (solar buildings for poultry/livestock), Triangle Mobilier (custom retail furniture for GMS chains), Triangle Énergie (agricultural solar buildings and roof renovation), Triangle Horizon (subcontractor for large-account solar projects), Developp'Sun (turnkey solar parking canopies), Triangle Autoconso (residential rooftop and kit systems), Triangle Sol'R (utility-scale solar fields and agrivoltaics, 1-30 MW), and Triangle Maintenance (O&M and supervision services). Customer segments span farmers, large retail (GMS), industrial and large commercial accounts, and individual homeowners. Technology components include photovoltaic modules (sourced in partnership with Trina Solar), metal structures fabricated in-house, agrivoltaic integration, and battery storage integration via partnership with Reservoir Sun. Cumulative installed capacity is 1.4 GW with 15% market share in the French agricultural and GMS solar segments.
The business model combines one-time project revenue (design, manufacturing, and installation of PV systems) with a recurring maintenance and supervision stream via Triangle Maintenance. Pricing is project-specific and quote-based, varying by installation type, capacity, and customer segment — no public pricing exists. Go-to-market is sales-led through specialized subsidiary commercial teams, with dedicated Technico-Commercial roles covering at least 20 French departments, supplemented by subsidiary-specific websites and participation in industry events such as Game Fair. In FY2024 the group reported revenue of €450M with 25% year-over-year growth and 950 full-time employees across all subsidiaries, making it a mid-cap industrial player by French standards. The ownership structure is founder-led and family-controlled, with no external private equity, institutional investors, or public listing disclosed, and no funding rounds, M&A, or leadership transitions recorded in the available data.

Le Triangle Group competitors and assessment
Company assessmentDirect peers
- Photosol: French solar developer and EPC focused on rooftop, ground-mount and agricultural PV. Competes directly with Le Triangle's utility-scale, agricultural, and commercial installation offerings in the French market.
- Sun'R: French agrivoltaic specialist offering solar fields and dual-use agricultural solutions. Direct overlap with Triangle Sol'R and Triangle Énergie in agrivoltaics and agricultural solar buildings, serving the same French customer base.
- Voltalia: French renewable energy operator active in solar, wind, and storage EPC. Comparable to Le Triangle's industrial and utility-scale segments (Triangle Horizon, Triangle Sol'R), with broader portfolio overlap in PV project execution.
- GreenYellow: French energy efficiency and solar solutions provider (also a partner of Le Triangle). Directly comparable in distributed solar deployment for commercial/retail accounts — overlapping with Triangle Horizon and Developp'Sun's parking canopy business.
- Neoen: French independent power producer developing utility-scale solar and storage projects. Overlaps with Triangle Sol'R on utility-scale solar field development and storage integration in France.
- Reservoir Sun: French solar and storage solutions provider (also a partner of Le Triangle). Comparable product offering combining PV and battery storage for self-consumption, mirroring Triangle Autoconso's residential and Triangle Maintenance's storage-integration play.
Emerging players
- K2 Systems: German manufacturer of solar mounting and racking systems. Comparable to Le Triangle's structural BOS / metal structure manufacturing capability integrated into its PV installations.
- Mounting Systems: European manufacturer of solar mounting structures and racking. Direct overlap with Le Triangle's in-house structural BOS manufacturing and metal structure value chain.
- BayWa r.e. European renewable energy developer with strong agrivoltaic and agricultural solar portfolio. Comparable to Triangle Sol'R and Triangle Énergie's agrivoltaic offerings, with broader European reach but overlapping technology and use cases.
Others
- Trina Solar: Global leading PV module manufacturer (also a partner of Le Triangle). Adjacent value-chain participant whose modules Le Triangle integrates into its projects; relevant as an upstream supplier and benchmark for solar scale.
