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 general, the Luxembourg government subsidizes a certain percentage of the investment amount in a new photovoltaic system, as each additional system is considered a contribution to a more sustainable energy production. The respective amount of the subsidy depends on whether you only want to feed the generated energy into the grid or if you want to consume it yourself.
Subsidies are subject to change (Klimabonus).

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.
