Frequently asked questions
How much does a photovoltaic system cost in Luxembourg?
As a guide, a turnkey residential system costs between €1,600 and €2,200 per kWp incl. VAT depending on size and roof, i.e. about €10,500 to €13,000 for 6 kWp before subsidies. A 5 kWh battery costs €3,500 to €5,500. After Klimabonus and communal aid the net cost is often halved. Our calculator gives a first estimate.
How much does a system produce in Luxembourg?
About 950 to 1,050 kWh per kWp per year for a roof facing south, south-east or south-west with a 20 to 40° pitch. An east-west system produces 10 to 15 % less but spreads it better over the day. A 6 kWp roof in Luxembourg City produces 5,400 to 6,600 kWh a year.
What does Creos do and how long does it take?
Any installation above 800 W must be declared to the grid operator. We file the request on myCreos, Creos sets a pilot appointment and sends the connection contracts, then our electrician notifies the end of works via Smarty PRO. Creos inspects and installs the bidirectional meter within 30 days of approval. Allow 6 to 12 weeks in total depending on the season.
How much Klimabonus can I get in 2026?
The aid for the PV installation follows the formula P × (1,155 − 33 × P) €: €2,178 for 2 kWp, €4,950 for 5 kWp, €8,250 for 10 kWp and €10,000 maximum from 15 kWp. A battery adds up to €2,250 (from 9 kWh). Communes often top up 20 to 50 % of the State aid.
What is prefinancing? Do I have to advance the money?
No. Handelux is listed in the Ministry of the Economy's register of installers admitted to the prefinancing procedure. We file the request in your name, the Klimabonus is deducted directly from our final invoice and the State pays it to us. The deposit at signature is capped at 30 % of the price incl. VAT.
