Practical guides on solar power in Luxembourg
Three guides to understand how a solar installation works before requesting a quote: self-consumption, battery storage and surplus resale. For the financial side, see also our page on subsidies and the Klimabonus 2026.
Self-consumption
How self-consumption works, why the rate varies from one household to another, and whether a battery is needed.
Battery storage
When a battery becomes worthwhile, how it raises your self-consumption rate, and what it changes day to day.
Surplus resale
How selling the electricity you don't consume works, who it suits, and how it combines with the Klimabonus.
Older or terraced roof
Roof frame, heritage protection, forced orientation: what to check before installing panels on an older house.
Maintenance and lifespan
Real lifespan of panels, manufacturer warranties, maintenance needed and inverter replacement.
