Solar panels — capacities and costs in Luxembourg at a glance
A photovoltaic system produces your electricity right on the roof — kWh whose price no longer moves, with the surplus sold to the grid. Installations differ mainly in capacity (kWp), whether a battery is added, and the revenue model — self-consumption or feed-in tariff.
On this page: why solar in 2026, the real Luxembourg price ranges, the grants and feed-in tariff, and how to receive two comparable quotes within 24 hours — free of charge.
Why solar in 2026: your electricity at a price you know
Electricity in Luxembourg costs markedly more than five years ago. A roof with panels delivers kWh whose price no longer moves — and the surplus is sold to the grid.
−50 to −70% on the electricity bill
Every kWh you use from your own roof is a kWh you no longer buy. That is the first line of the payback calculation.
The surplus is sold
What you do not use goes to the grid and is paid at the feed-in tariff. Your panels work even when you are out.
Your home gains value
A roof that produces electricity improves the energy passport — and shows up in the price on the day you sell.
Sheltered from energy prices
Your solar kWh cost the same in 10 years as today. Tariff rises only affect the rest of your consumption.
A battery to go further
It stores the midday surplus for the evening and pushes up your self-consumption share. Your two quotes price both scenarios.

Solar panels: your questions
How much does a solar installation cost?
For a house, expect €8,000 to €18,000 depending on capacity (kWp) and storage, before grants. Your two quotes price the payback, with grants and feed-in income included.
Is it worth it in Luxembourg?
Yes, thanks to self-consumption, the feed-in tariff and the grants. Payback usually lands between 8 and 12 years.
Is my roof suitable?
Orientation, pitch and shading matter, but many Luxembourg roofs work well. Your installers assess your roof in the quote.
Do I need a battery?
Not compulsory. A battery raises self-consumption but also the cost. Your installers price both scenarios.
How many installers will contact me?
Two at most. Never 5, never 27. It is written into our contract.
Is it free for me?
Yes, €0. HomeUpdate is paid by the trade companies, never by homeowners.
