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.
Projects benefit from a market premium contract for the injection of the electricity produced for 15 years. Note that buildings and non-eligible areas are excluded.
Here are the different lots included in this second call for tenders:
Lot 1: Vertical bifacial panel power plant or Tracker (power > 100 kWp and ≤ 5 MWp).
Category 1: Grassland used for fodder or grass production.
Category 2: Grassland used for livestock farming (including poultry farming).
Category 3: Arable land for all crops (including special crops).
Lot 2: Photovoltaic canopies (power > 100 kWp and ≤ 5 MWp)
Category 4: Special crops.
Lot 3: Ground-mounted power plants (output > 100 kWp and ≤ 5 MWp)
Category 5: Grassland (forage and livestock) and arable land.
Consult the practical details on guichet.lu. The specifications can be requested by e-mail from: PV@energie.etat.lu.
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 self-consumption: submitting the application for self-consumption to the grid operator
For the surplus electricity to be injected: sign an electricity buy-back contract at the market price with a supplier
If participating in a call for tenders with investment aid: submit the request for payment of the aid via the tool on MyGuichet.lu.
Apply for remuneration for the electricity produced by the photovoltaic system, depending on the specific situation:
Guaranteed feed-in tariff under the Klimabonus subsidy scheme (< 30 kWp) with the grid operator
Feed-in tariff without investment aid for installations >30kWp to < 400 kWp with cooperative with the grid operator.
Market premium with or without a call for tenders for photovoltaic installations from 400 kWp to 10 MWp with the grid operator and conclusion of a contract for the direct sale of the electricity with an agent who is normally a supplier.
The subsidy must be applied for after the installation has been completed, unlike other subsidies, where applications for subsidies must be made in advance of the commitment to carry out the project via MyGuichet.
