Businesses and commercial roofs
10 to 200 kWp on halls, offices and farms: self-consumption, feed-in or a mix.
Request a quoteFor a business, photovoltaics is first of all a hedge against rising prices: every self-consumed kWh replaces a purchased one. Commercial roofs offer large flat areas where 100 kWp fit on about 500 m².
We size the system on your load curve, prepare the Creos file (pilot approval, decoupling protection, meter) and guide you between self-consumption, guaranteed feed-in tariff or tender depending on the power. Up to 30 kWp the Klimabonus remains available to self-employed persons and small businesses (de minimis rule).
Good to know
What happens after the installation?
You receive the acceptance report, the conformity declaration, the data sheets and access to the monitoring app. We follow the Klimabonus file until payment, send you the decision for the communal application and stay available for any question. Three weeks later we ask for your feedback.
Do the panels need maintenance?
Very little: rain cleans pitched modules. A check every 5 to 10 years and occasional cleaning on flat roofs or near trees are enough. The monitoring alerts you, and us, in case of an abnormal production drop.
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.
How long is the payback period?
With the Klimabonus, the communal aid and rising electricity prices, most of our customers pay back their system in 7 to 11 years, for a lifetime of 30 years and more. Our offer includes a personalised simulation.
