What Tecsol Antilles does

Tecsol Antilles-Guyane is an independent engineering consultancy (bureau d'études) founded in 1996 and headquartered in Baie-Mahault, Guadeloupe. It provides technical design, engineering, and advisory services across HVAC (génie climatique), electrical engineering (génie électrique), photovoltaic and solar-thermal systems, environmental/energy certification (HQE, RT), digital advisory (numérique), and professional training (formation). The firm operates across the French Caribbean and South American overseas territories — Guadeloupe, Martinique, French Guiana, and Saint-Martin/Saint-Barthélemy — and is affiliated with the broader TECSOL group, which carries roughly 40 years of solar engineering experience.

The company serves a diversified base of institutional, enterprise, and public-sector clients, including CNES (Guiana Space Centre, for which it has engaged on three 5 MWc solar plants and the HYGUANE hydrogen initiative tied to Ariane 6), EDF, Crédit Mutuel, La Poste, Club Med, the Pullman hotel, Icade, the Région Guadeloupe/SEMAG, and CHU Guadeloupe. Its technical differentiation includes exclusive rights to deploy the Sunchain blockchain platform for energy/solar certification within departments 971–973, positioning it as the local channel for traceable energy attestation.

The business model is project-based professional services: fee-for-engagement engineering studies, design and certification work, and a training arm that is DataDock-certified and referenced by DIECCTE. Revenue is generated through discrete, often multi-year technical mandates rather than recurring subscription income, with the firm positioned as supplier-independent (no equipment resale tie-ins), reinforcing advisory neutrality. It is pursuing ISO 9001 and ISO 14001 certification, signaling a formalization of quality and environmental management processes.
