OUR PREMIUM SOLUTIONS

Swiss Energy Ecosystem

Advanced technologies integrated with rigor and precision to maximize your energy independence in the long term.

Photovoltaic

Design and installation of bespoke solar photovoltaic systems in French-speaking Switzerland. We install high-performance panels (Megasol, Enphase, SolarEdge) and handle all the necessary procedures on your behalf to secure the Pronovo one-off payment and cantonal grants.

Batteries & Storage

Store your surplus solar energy so you can use your own electricity day and night. Our smart batteries (Sigenergy, Huawei) maximise your self-consumption rate and ensure a reliable power supply in the event of a grid outage.

Rechargeable batteries

Installation of smart charging points (IRVE) at home or at work. Charge your electric vehicle directly using surplus solar power thanks to dynamic load management.

Heat Pumps

Replace your old oil or gas heating system with a high-efficiency air-to-water or ground-source heat pump (Stiebel Eltron, Vaillant). When combined with your solar panels, your heat pump can reduce your heating bills by up to 70 per cent, whilst also allowing you to benefit from grants under the Buildings Programme.

Solar Carports

Bespoke solar carport in aluminium or timber. Protect your vehicles from the elements whilst generating your own green electricity and charging your electric car directly.

Flushing & Maintenance

Maintenance, cleaning and hydrodynamic descaling of your underfloor heating systems and radiators in French-speaking Switzerland. Remove sludge and limescale to restore your heat pump’s efficiency.
