GTS Solar SA
Crissier VD
Tap a star to rate
GTS Solar is one of the largest regional solar installers in French-speaking Switzerland and knows the subsidy programs of the cantons of Vaud, Geneva, Fribourg, Valais and Neuchâtel well. Its 15 installation teams keep the wait between placing an order and commissioning comparatively short.
The range covers everything from small home installations to agrivoltaics and solar carports, plus support for architects on new-build projects. The website is in French, though advice is available bilingually.
