A photovoltaic installation alone uses 30% of your production. With the right battery, self-consumption rises to 70–80%. But beware — a poorly sized battery is wasted money. We know how to make the difference.
During the day, your panels produce far more than your consumption. Without a battery, the surplus is fed back to the grid at a fraction of the price. In the evening and at night, you buy back expensive electricity. Result: you give away the value of your production.
A correctly sized lithium battery shifts this energy. You consume in the evening what you produced during the day. The bill drops 60–80%, depending on profile.
We install only LiFePO4 (iron phosphate) batteries — safer, longer-lasting, more fire-stable than older technologies. Lifespan 10–15 years, 6,000+ cycles manufacturer warranty, deep discharge up to 95%.
The right size: the one that covers your real consumption between 6pm and 7am. Never more. We calculate it from your load profiles.
With a hybrid inverter (backup function), your battery automatically powers critical circuits during a grid outage: lighting, fridge, internet box, heating, some outlets. Switchover in 20 ms — you don't notice the outage.
A concrete benefit in French-speaking Switzerland, where outages are rare but locally intense during storms.
