How does a photovoltaic installation work?
Each installation is tailored to the specific characteristics (inclination, orientation) of the roof of the house, garage, or building on which it is to be installed. The panels, through their photovoltaic cells, convert solar radiation into direct current. The produced current then passes through an inverter, which generates alternating current, making it suitable for a domestic installation.
Self-consumption or full feed-in: the choice is yours!
By opting for self-consumption, you use the electricity generated by your solar panels, reducing your reliance on the grid and lowering your energy bills. Any excess power produced is fed back into the grid and sold.
Opting for full injection of your green electricity production ensures you receive a fixed, 15-year state-guaranteed feed-in tariff and prevents you from consuming any electricity generated by your photovoltaic installation.
What subsidies are available for photovoltaic systems?
In principle, the Luxembourg government subsidizes a certain percentage of the amount invested in a new photovoltaic installation, as each additional installation is considered a contribution to more sustainable energy production.
Subsidies are subject to change (Klimabonus).
You can simulate your subsidies on https://aides.klima-agence.lu/?lng=en
To benefit from the current subsidies, you must operate your installation for self-consumption.
What are the conditions for receiving Klimabonus subsidies?
Option 1 - Current scheme: no pre-financing
Amount of subsidy
50% on investment costs (max. €37,500 with battery)
Injection tariff
| Market price-linked remuneration |
Application deadline
| Valid for offers signed until 2026-03-04 |
Option 2 - New scheme: with pre-financing*
Amount of subsidy
Depending on the capacity of the installed system (max. €12,250 with battery)
Injection tariff
Market price-linked remunerationApplication deadline
Valid for offers signed until December 31, 2029
*Subsidies are deducted directly from the installation price, so there is no need to wait for reimbursement.

When the PV system is first installed, annual costs are minimal. After a few years of use, over a period of around 5 to 10 years, maintenance work starts to become more essential.
It's not possible to give a general answer to this question, as it depends on the self-consumption of the electricity generated by the photovoltaic system. The more electricity produced during the day is used for direct self-consumption, the higher the savings on energy requirements purchased from the public grid.
In theory, you can use your photovoltaic system to inject everything into the grid of the electricity grid operator, or you can also declare self-consumption, which allows you to inject part of the electricity produced by the system directly into your home grid and thus cover part of your consumption. Since a photovoltaic system can only produce electricity when the sun is shining, your chosen electricity supplier will continue to supply you during the morning and evening hours when the sun is not present.
