Home battery: is it worthwhile in Luxembourg?
With new Klimabonus subsidies and rising electricity prices, home batteries are becoming increasingly attractive in Luxembourg. A complete profitability analysis.
How home batteries work
A home battery stores solar energy produced during the day for evening and night use. Self-consumption rates typically rise from 30% to 70-80%.
Available subsidies
Klimabonus 2026 includes specific subsidies for home batteries, stackable with PV subsidies. For a 10 kWh battery, the subsidy can reach €3,750.
Profitability calculation
With an average electricity price of €0.25/kWh and a 10 kWh battery, you can save approximately €600-800 per year. After subsidies, payback time is 6 to 8 years.
Our recommendation
Home batteries are particularly worthwhile with high evening consumption, an electric vehicle, or a desire for maximum energy independence.
