To make this measure more effective and tailored to the specific context of your company, we recommend that you first perform an overall analysis of your energy situation.
Photovoltaics: an environmentally and financially interesting alternative for your company’s electricity production
A photovoltaic installation enables you to produce renewable electricity and to decouple part of your electricity costs from market price fluctuations. Beyond self-consumption, there are other support mechanisms that can represent an interesting economic model, such as the guaranteed feed-in tariff or the market premium resulting from a call for tenders. The installation can be financed from your own funds or by a third-party investor, who can also take care of its planning and completion.
Definition of the requirements
Analysis of plant location and solar potential – solar cadastre
Analysis of load curve and estimation of degree of self-consumption Request consumption data from the grid operator or supplier (possibility of requesting through the supplier’s online portal) and compare with the photovoltaic system’s forecast production to estimate the degree of self-consumption.
Project implementation by a project developer / third-party investor For installations of 100 kW or more, it is possible to commission a photovoltaic project developer who can take care of the development, financing, construction, operation and maintenance of the installation.
Identify solution and check feasibility of photovoltaic panel installation project
General planning of the installation (depending on the scope of the project, in collaboration with a qualified craftsman or design office)
Possibility of including plant maintenance in the offer
Subsidy application
Government subsidies
Please note: any application for government or non-government subsidies must comply with the “incentive effect”, subject to compliance with the subsidy conditions. In order to respect the “incentive effect”, no binding commitment (signing a quotation; paying a deposit) may be made BEFORE having received the agreement in principle from the State or the electricity and natural gas supplier following an application for subsidy.
Either the investment subsidy of 62.5% (until 30 September 2024 with a subsequent 50% investment subsidy starting 1 October) for the installation of photovoltaic modules operated in “self-consumption mode” without a guaranteed feed-in tariff. Power storage systems are subsidised if the building is not used for residential purposes and the storage capacity is ≤ 1 kWh/kWp. In this case, the feed-in tariff is not guaranteed and it is necessary to sign a contract with a provider to buy the surplus electricity.
Or an investment subsidy of 20% for the installation of photovoltaic systems operated in “feed-in mode” and a guaranteed feed-in tariff for a period of 15 years with a cap of 500€ per kWp. Self-consumption is possible under this option.
The extended aid scheme “SME Packages Sustainability” provides more incentives for companies to invest in measures that significantly improve their environmental impact. Photovoltaic installations are subsidised at 70% for small, 60% for medium and 50% for large enterprises for projects costing more than €7,500, with a maximum amount of €100,000.
Subsidies following a call for tenders for photovoltaic projects > 30kWp, with priority given to self-consumption.
There is currently no call for tenders for large-scale photovoltaic installations, but we will inform you as soon as a new call for tenders is issued. It is, however, possible to take advantage of the feed-in tariff.
For reference, the last call for tenders closed on 31 October 2023:
If the installation is > 200 kWp for direct injection or > 30 kWp for self-consumption, you can apply for subsidies following a call for tenders. The subsidies are awarded following a call for projects, which involves a selection process: the projects that require the least amount of financial support in relation to the installed capacity will be selected, within the limits of the available budget.
Please note: this call for projects is not to be confused with a call for tenders, which aims to award a market premium.
Agri-PV pilot call for tenders (closed since 1st August 2023)
For detailed information on this call for projects, please consult MyGuichet.lu. Applications must be submitted via the MyGuichet.lu platform (see “Services en ligne & Formulaires “) in accordance with the specifications. For guidance, you can also consult the guide published by Luxinnovation.
N.B. Government subsidies cannot be accumulated for the same project. The incentive effect must be respected when applying for subsidy following a call for tenders.
Applying for permits
Municipal permits depending on the municipality where the project is located.
In the case of a system < 30 kWp , apply for the government Klimabonus subsidy
In the case of an application for Klimabonus subsidies, the application must be made after the installation has been completed, unlike other subsidies where the subsidy must be applied for in advance of the project.
