Tomorrow’s electrification with energy efficiency


The electrification of tomorrow is on the move, and solar energy is becoming an essential response to the challenges of our time. Blackouts and energy shortages are regular themes, as are the increase of demand due to urbanisation, the development of IT technologies and of industry. But thanks to solar energy, we have a reliable, sustainable and affordable solution.


Solar panels are getting both more affordable and more efficient, which means that households and businesses can now generate their own electricity from the sun. This reduces dependence on traditional energy suppliers and provides a more stable and predictable source of energy.

Prices going up? Inflation? It’s no longer a problem for you!


If electricity prices for homes and businesses increase in the near future, you’ll be able to consume your own energy free of charge. Our entirely Swiss made solution, which is managed automatically, allows an average of 85% of electricity consumption to come from the sun on your roof. With storage batteries, solar power can be used even at night. The system is flexible, adapting to all changes in energy requirements.
