From project design to maintenance twenty years later, Swiss SunTech masters the entire energy chain. No link delegated, no approximation. Discover our five areas of intervention.
A high-performance solar installation relies on much more than a panel. It requires rigorous design, impeccable electrical work, intelligent storage and flawless monitoring. That's why we cover the five areas rather than subcontracting what falls outside our original trade.
Production study, custom sizing, architectural integration and Pronovo connection. For private individuals, co-ownerships and industrial clients in French-speaking Switzerland.
Double your self-consumption. LFP and new-generation lithium-ion technologies, capacity 5 to 100+ kWh, warranties up to 15 years.
Electrical works, NIN compliance, switchboard renovation, grid connections, EV chargers. ESTI/OIBT compliance guaranteed.
In-house engineering office: feasibility, PVsyst simulation, execution plans, authorisation files. From sketch to installation, no broken telephone.
Annual contracts Essentielle, Confort, Sérénité. 24/7 monitoring, rapid intervention, periodic cleaning. A monitored installation lasts twenty years longer.
Our articles cover the entire energy spectrum: photovoltaic, thermal, wind, hydro, geothermal. A specific request? Let's talk about it.
Five trades mastered in-house. No link delegated.
It's the least we can do when signing for twenty-five years.
Whether you entrust us with one trade or several, you speak to the same people: the engineering office that designs, the team that installs, the technician who comes back for maintenance. This continuity is what makes everything still work twenty years later.
A single contact assesses your entire project — photovoltaics, electrical, storage — in a single visit.
Detailed quote covering all relevant trades. Not three companies, not three invoices, not three calendars.
Our teams intervene in the right order, with no downtime. A single project manager steers the whole thing.
Production monitoring, equipment maintenance, electrical repair: one contract, one phone number.
For projects combining several of our trades (PV + battery + charger, or complete electrical renovation), talk to us early. The sooner we integrate, the better we optimise.
