Quote: photovoltaic panel installation
E.g.: 6 kWp installation on a pitched roof, Creos grid connection

Describe roof condition, slopes and nearby obstacles. Add available plans or photos, consumption and genuinely planned future uses. Request a layout, proposed capacity and explained generation estimate. Occupant count alone cannot determine panel numbers.
Check the roof before counting modules
Assess support, covering, weatherproofing, usable zones and maintenance access. Specify mounting and effects on the building. A flat roof does not automatically require ballast; integrated panels are not solely an aesthetic decision.
Connect capacity to expected generation
Request location, orientation, slope, losses and shading assumptions. PVGIS estimates generation; interpret results against site constraints. Annual output establishes neither independence nor a self-consumption rate.
Define electrical scope and responsibilities
Identify modules, inverter, protection, cable routes and any distribution-board adaptation. Specify monitoring, data access and future options. Have the contractor confirm checks and documents required for commissioning.
Separate network connection and surplus sale
Identify your address’s operator. Creos describes application, technical approval and stages depending on metering configuration. In its process, a surplus-purchase contract is signed with the chosen supplier. Network operation is not purchase of all generated electricity.
Check the offered grant regime
For supported PV self-consumption under Klimabonus 2026, Guichet requires waiving regulated feed-in remuneration; market sales remain possible. Specify regime, dates and procedure. Estimated support does not justify automatic combination with a guaranteed export tariff.
Indicative prices in Luxembourg
On quotation
Compare tax-inclusive cost before grants, identified equipment, mounting, access, connections and procedures. Separate battery and roof work. No local average or flat roof-type surcharge is established; comparable offers require the same project basis.
Subsidies and grants
No grant is deducted from the budget shown here. If a quote mentions support, request the exact scheme and confirmation of your eligibility before including it in financing.
Frequently asked questions
How many panels for a household?
Assess roof, generation and consumption profile; occupant count is insufficient.
Does Creos serve every address?
Check the relevant operator and process; do not automatically assign every installation to Creos.
Can I count the grant at quotation stage?
Separate estimated and confirmed amounts with the applicable conditions and procedure.
Do all panels have the same warranty?
Compare product, performance, inverter and installation warranties for the proposed equipment, without a universal duration.
