How to choose the right provider
Ranking well for a service search depends on proving useful decision support, not just naming the service. These are the checks users should be able to complete before making contact.
Klima-Agence accredited installer
Only firms listed on klima-agence.lu can unlock Klimabonus. Cross-check the company name and autorisation number before signing any quote.
An installer who promises Klimabonus but cannot show their Klima-Agence listing is misleading you. Walk away.
Panel, inverter and workmanship warranties
Panel product warranty should run 25 years, inverter 10 years minimum (12–15 preferred), and installation workmanship 10 years via decennial cover. Ask for certificates on letterhead.
On-site shading analysis before quoting
A credible installer shows up with a solar pathfinder app (Sun Surveyor, PV*SOL or Aurora) and models chimney, tree and neighbouring-roof shadows across the year. A quote built only on Google-satellite roof area understates shading losses by 10 to 25 % — a gap that destroys payback math.
A quote produced remotely from a roof photo and address alone, without a site visit, is not a serious technical proposal.
Tier-1 panels and reputable inverter brand
Insist on Tier-1 module manufacturers (Bloomberg list: LONGi, Jinko, Trina, Q Cells, REC) with 400 W+ half-cell cells. For the inverter, Fronius, SMA, SolarEdge and Huawei are the brands most Luxembourg electricians can service. No-name inverters often fail 5 to 7 years in, after the original installer has disappeared.
When to contact a provider
Planning a roof renovation
Solar panels added during a re-roof save 15 to 20 % on scaffolding and roofing labour. Book the PV installer before signing with the couvreur — the two trades share the same fixing points.
Applying for Klimabonus 2026
File the pre-agreement on guichet.public.lu before signing the quote. The installer must be on the Klima-Agence register; if they're not, the application is rejected regardless of equipment quality.
Adding an EV wallbox or heat pump
A heat pump and EV charger together push household demand above 6 000 kWh/year. Size the array for that baseline, not last year's bill — otherwise the self-consumption ratio collapses.
Monthly electricity bill above €200
A Luxembourg household paying €200+ per month to Enovos or Leo is consuming roughly 6 000 to 8 000 kWh a year — the profile where a 5 to 8 kWp array pays back in 8 to 10 years after Klimabonus. Below €120 monthly, self-consumption rarely justifies the capex unless a heat pump or EV is on the horizon.
What to compare in quotes
- Compare roof suitability, system size, production assumptions, equipment warranties and grid-connection work; distinguish the installation price from assumed subsidies.
- Roof survey, shading, system size, panel/inverter brands, mounting method, battery option, and production estimate.
- Grid connection, bidirectional meter, subsidy/admin support, commissioning, warranties, monitoring, and aftercare.
- Whether roof repair, scaffolding, electrical upgrade, EV charger, or heat-pump coordination is included or excluded.
Luxembourg checks before you hire
Permits depend on the commune
Construction, transformation, facade, roof, demolition, and change-of-use work can require a building permit from the mayor of the commune. Interior work that does not touch structure, facade, or roof is usually lighter, but commune rules still matter.
3% VAT can apply only under conditions
Eligible housing construction or renovation work may use Luxembourg's super-reduced 3% VAT route when the home is used as a main residence and the AED conditions are met.
Check business authorisation
For regular commercial, craft, and many liberal activities in Luxembourg, ask who holds the autorisation d'etablissement and whether the quoted work matches that activity.
Ask for insurance in writing
Before work starts, get civil liability or professional insurance details in writing, especially when the provider enters your home, handles keys, or works on fixed installations.
FAQ
How much does a 5 kWp solar system cost in Luxembourg?
A turnkey 5 kWp rooftop system runs €9 000 to €12 000 installed before subsidies. Klimabonus 2026 refunds up to €500 per kWp (capped at 50 % of the invoice), bringing the net cost to roughly €7 000 to €9 500. Payback sits between 8 and 12 years depending on self-consumption ratio and feed-in tariff.
How do I claim the Klimabonus for solar panels?
File the pre-agreement (accord de principe) on guichet.public.lu before signing the installer's quote. The installer must be listed on Klima-Agence. After commissioning by Creos, submit the final file with invoice, commissioning certificate and photos. Payment typically follows within 12 to 16 weeks.
Do I need a battery with my solar panels?
Not necessarily. A battery makes sense when your self-consumption ratio sits below 40 percent without one — typically households away during the day. At current Luxembourg feed-in tariffs, the payback on a battery alone runs 10 to 14 years, so it only makes financial sense when paired with a heat pump or EV charging at home.
How long does a solar installation take in Luxembourg?
From signed quote to energised system, count 3 to 5 months: 6 to 10 weeks for panel and inverter delivery, 1 to 3 days on the roof, and 4 to 8 weeks for Creos to swap the meter and commission. Klimabonus payout arrives another 12 to 16 weeks after commissioning.
Useful cost signals
Turnkey installed cost (per kWp)
1.800 € - 2.400 €Covers panels, inverter, mounting, DC/AC wiring, labour and commissioning. Battery and complex roofs priced separately. Before Klimabonus. Excludes VAT (17 %, 3 % reduced rate if eligible).
Typical 5 kWp residential system (installed)
9.000 € - 12.000 €Standard pitched-tile roof, single azimuth, 12–14 panels. Klimabonus 2026 can refund up to €2 500 on this system. Net cost after subsidy typically €7 000–9 500.
Home battery storage, 5–10 kWh (installed)
4.500 € - 9.000 €Lithium-iron-phosphate pack with hybrid or AC-coupled integration. Add €1 000–1 500 for retrofit on an existing PV system versus new-build bundle.
