What Occisolis does
Occisolis is a French photovoltaic engineering and installation firm founded in 2009 in Cagnac-les-Mines (Tarn department) by Laurent Bernal and Sébastien Labbé, headquartered at 4 Rue Jean le Rond d'Alembert, 81000 Albi. The company designs, supplies, installs, and maintains solar photovoltaic systems across three primary customer segments: individual homeowners (particuliers), professionals (businesses, real estate developers, social housing/HLM companies, and national contractors), and local governments (collectivités territoriales). It has completed more than 1,500 installations across approximately 400 communes in France (including DOM-TOM) and Spain, with a record year in 2021 when the company doubled both workforce and installation volume.
The core offering is end-to-end turnkey project delivery: feasibility studies, supply of tier-one equipment (Systovi and Axitec panels, SMA/SolarEdge/Enphase inverters, Joris Rail mounting), installation by in-house specialized teams (carpenters, roofers, electricians), and preventive maintenance with production monitoring. Specialized services include a proprietary "Cadastre Solaire" mapping tool for territorial solar potential assessment, collective self-consumption coordination for multi-site municipal projects within a 1 km radius, and full administrative procedure management covering ENEDIS grid connection, EDF Obligation d'Achat (EDF OA) purchase contracts, and Consuel certification. An aerovoltaic combined electrical/thermal module (Systovi Rvolt) is offered as an add-on for projects requiring heat plus power.
Revenue is generated primarily through one-time installation contracts (residential 3–9 kWc, commercial/municipal up to 500+ kWc), supplemented by recurring maintenance subscriptions, administrative process management fees, and facilitation of the regulated 380€/kWc investment bonus paid over five years through EDF OA. Surplus electricity is sold to EDF OA under 20-year purchase contracts at government-regulated feed-in tariffs (e.g., 17.89 c€/kWh for ≤3 kWc full resale). Go-to-market is direct sales-led with dedicated commercial representatives per segment (Pierre Izard for individuals, Laurent Bernal for professionals and local governments), supplemented by industry positioning through Sébastien Labbé's presidency of GMPV Tarn and Laurent Bernal's membership in the CEMATER renewable energy cluster.
