panneaux-solaires.lu is an independent service that turns Luxembourg's official solar cadastre into a clear assessment, municipality by municipality, roof by roof. Our goal: that every homeowner knows, without jargon and at no cost, what solar power can bring them.
The data comes from the official solar cadastre developed by the Klima-Agence and tetraeder.solar, published in the “Solar potential in Luxembourg” dataset on data.public.lu. We combine it with transparent calculation assumptions to produce indicative estimates.
Our model, in three steps
Public data
We use Luxembourg's official solar cadastre: the photovoltaic suitability of every roof and the ground footprint of buildings.
Free assessment
You enter your address or your municipality. In a few seconds we estimate the possible capacity, the output, the savings and the CO₂ avoided.
Connection
If you wish, we forward your request to a partner photovoltaic installer for a precise, no-obligation quote.
Transparency
We are a connection intermediary. We don't install panels ourselves: we direct your request to partner photovoltaic installers established in Luxembourg. The service is free and with no obligation for you; we may be paid for this connection.
The figures shown are indicative estimates intended to give you an order of magnitude. The exact values (usable area, orientation, shading, grid connection, price, grants) are determined during an on-site visit by an installer.
