Why one company
No subcontractors. One contact from the first call to the last adjustment.
An energy project touches the roof, the electrics, the heating and often the façade. Elsewhere that means three companies and three quotes. At Ecolive Lux, roofers, electricians, heating engineers and solar installers work together, under one responsibility.

Klimabonus 2026 · law of 24 July 2026
How much the State refunds. Calculated with the official formula.
The Klimabonus Wunnen 2026 scheme runs until the end of 2030. For photovoltaics and storage, the aid depends on installed power and capacity, and since 2026 the installer deducts it directly from your invoice.
Formulas and caps (€10,000 from 15 kW; €2,250 from 9 kWh): guichet.lu, “technical installations” aid, Klimabonus 2026, consulted 30/09/2026. Indicative estimate, excluding municipal grants.

Frequently asked
What we are asked before signing.
Do I have to advance the Klimabonus amount?
Not for photovoltaics and storage: since 2026 the participating company deducts the aid from the invoice and is reimbursed by the State (pre-financing). This extends to heat pumps and insulation from 1 January 2027. Source: Klima-Agence, consulted 30/09/2026.
How many panels for a house in Luxembourg?
Usually 8 to 14 panels depending on annual consumption, orientation and available roof area. The free survey calculates it from your bills and your roof.
Does a heat pump suit an older house?
Yes if the envelope is decent, which is exactly why we also do insulation and roofing. The 2026 scheme requires a 35 °C flow temperature or an equivalent COP, a heat meter and hydraulic balancing: our heating engineer checks all of it.
Do you work across the whole country?
Yes. Head office in Doncols, in the north, and teams across the Grand Duchy with no travel surcharge.
