What tera solar does

tera solar is a Swiss photovoltaic (PV) installation specialist serving French-speaking Switzerland (Suisse romande) from its base in Thônex, Geneva. Founded in July 2022, the company operates four regional agencies covering the cantons of Geneva, Vaud, Valais, and Neuchâtel, with a stated geographic reach extending to Fribourg and Jura. The business delivers turnkey solar solutions built on a core PV panel installation platform, extended through modular add-on offerings including solar battery storage, EV charging stations, solar carports, collective self-consumption (CEL/RCP) solutions compliant with the 2024 Swiss electricity law, and a solar contracting (third-party ownership/PPA) model that removes the upfront capital barrier for customers. Technical differentiation is modest and execution-driven rather than IP-driven, evidenced by specialized installation capabilities such as facade-mounted systems using Swisspearl Sunskin modules (e.g., a 1,920m altitude off-grid project at Col de Cou), flat-roof ballasted systems, and complex multi-building community solar deployments.

The company generates revenue through a hybrid mix of one-time project sales (turnkey installations with equipment, labor, and administrative support) and recurring revenue streams via its solar contracting offering, where tera solar finances and owns the system while customers pay for the energy consumed. Go-to-market is direct and sales-led, combining an inbound online solar calculator for lead capture with in-person solar energy advisors across each regional agency. The customer base spans individual homeowners (particuliers), SMEs, large enterprises, property managers, and public-sector clients, with named references including Balexert, SIG, TCS, Edmond de Rothschild, Rollvis, Golf Club de Genève, and several communes. Subscription to the SIG éco21 quality program, Swissolar industry association membership, SUVA safety charter adherence, and the 2025 SIG Éco21 Trophy for energy transition underpin the company's regulatory positioning and brand credibility in a fragmented regional market.

Revenue model

1. Solar panel installation sales: Revenue is generated through the sale and installation of photovoltaic systems, battery storage, EV charging stations, and solar carports. Customers purchase turnkey solar solutions including equipment, installation, administrative support, and subsidy filing. Pricing is project-specific based on system size, panel count, and building type.
2. Solar contracting (third-party ownership): Under the contracting model, tera solar owns the installation and finances it entirely. Customers pay for the solar energy produced, typically at rates lower than grid electricity, with no upfront capital expenditure required. This creates recurring revenue over the contract term.
3. Energy surplus resale: Customers who produce more electricity than they consume can sell surplus energy back to the grid at regulated buy-back rates. This provides additional value to customers and incentivizes right-sized installations.
