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 50% 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.
The 6th call for projects to obtain an operating subsidy (15-year market premium contract) for the construction and operation of solar photovoltaic power stations in the Grand Duchy of Luxembourg is currently underway. The deadline for submitting proposals is 29 November 2024 (12:00).
The following lots are included in this sixth call for projects:
Lot 1: Industrial land (power > 500 kW and ≤ 20 MW).
Lot 2: Roofing of buildings (power > 200 and ≤ 500 kW).
Lot 3: Roofing of buildings (power > 500 kW and ≤ 5 MW).
Lot 4: “Innovative” (on a Building: roofs with lightweight modules, modules on facades)
Sub-lot 4a: > 200 kWp and ≤ 500 kWp
Sub-lot 4b: > 500 kWp and ≤ 3 MW
Lot 5: Shade or water basins (power > 30 kW and ≤ 3 MW)
The subsidies are awarded following a call for projects, which means that the projects requiring the least amount of aid in relation to the installed capacity will be selected, within the limits of the available budget.
Detailed information on this call for projects can be found here (FR). The full terms and conditions of the call for projects are outlined in a set of specifications. The specifications will be sent by e-mail to all interested parties on request to the following address PV@energie.etat.lu.
As an alternative to these calls for projects, it is also possible to take advantage of the feed-in tariffs.
N.B. Government subsidies and calls for projects cannot be combined for the same project.
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.
