What Green Technology Solutions Solar does

GTS Solar (legal entity GTS SA, d/b/a GTS Solar) is a Swiss photovoltaic installation company headquartered in Crissier, Vaud, operating primarily across French-speaking Switzerland (Romandy) with maintenance services extending into parts of German-speaking Switzerland. The company designs, installs, and maintains solar energy systems — rooftop panels, building-integrated photovoltaics, solar facades, carports, agrivoltaic structures, photovoltaic fencing, battery storage, EV charging, and smart-home energy management — exclusively sourced from Trina Solar and Jinko Solar and monitored via Huawei and SolarEdge platforms.

The business runs a turnkey model covering feasibility study, design, permitting, Pronovo subsidy administration, grid-connection management, construction, and certification, supported by 15 in-house installation teams and a 6-technician maintenance unit. It serves five segments — Particuliers, Agriculture, Entreprise, Collectivité, and Constructeur — with named enterprise and public-sector clients including Ville de Lausanne, CFF (Swiss Federal Railways), the World Health Organization (OMS), SIG, BCV, Migros, Coop, and Intuitive Surgical, alongside a distributed base of 2,000+ completed residential and SMB installations.

Revenue is generated primarily through one-time installation projects (one-time/perpetual license), supplemented by recurring tiered maintenance contracts (Secure, Premium, Surveillance, Check-up), SRI energy surplus advisory, hardware supply (panels, inverters, batteries), and a participatory crowdfunding financing model for municipalities. The company was founded in 2008 by Jacques Hess on the back of a team originating from solar cell manufacturing in 1997, holds PRO du Solaire and ECO21 certifications, and joined MAGENTA Group in 2024, operating under the MAGENTA GTS brand with showroom corners at MAGENTA Home Design locations in Geneva, Fribourg, and Crans-Montana.

• Meyer Burger Technology AG: Swiss-headquartered vertically integrated PV manufacturer and rooftop-system provider. Comparable as a Swiss PV value-chain player, though operates at much larger scale with module manufacturing rather than purely EPC.
• SolarEdge Technologies: Global solar inverter and power-optimizer manufacturer whose platform GTS already uses for monitoring. Operates a comparable module-level solar electronics stack and has installer-channel partnerships across Europe.
• SunPower Corporation: Established US-headquartered residential and commercial solar installer and module manufacturer. Comparable turnkey rooftop and storage offering, though operating at much larger scale than GTS.

Direct peers

• BE Netz AG: Swiss solar installer specializing in rooftop and commercial PV projects with battery storage integration. Comparable to GTS in scope of turnkey rooftop and commercial installations within Switzerland.
• 3S Swiss Solar Solutions: Swiss manufacturer of integrated solar modules and provider of PV installation solutions, including solar roof tiles and facade systems. Comparable to GTS in BIPV/solar facade and turnkey Swiss EPC delivery.
• Helion Solar: Swiss solar installer serving residential, commercial, and industrial customers with turnkey PV solutions and storage. Directly comparable to GTS in scope, geography (Switzerland), and turnkey business model.
• TRITEC AG: Swiss PV system provider and installer offering solar modules, inverters, storage, and complete installation services. Closely comparable business model to GTS, also operating across Switzerland with a focus on turnkey delivery.

Regional players

• Enerix: German and Austrian franchise-based solar installer with turnkey residential and commercial PV offerings. Comparable turnkey service model to GTS, but primarily serves DACH markets rather than Switzerland.

Emerging players
