You have decided to install a solar plant on your roof. There are several steps to take into consideration.
Outside of Esch/Alzette – please contact the grid owner ( Creos, Ville d’Ettelbrück, Ville de Diekirch) and introduce a connection requestThe electrician must get information from the network manager of the customer’s municipality.
Feasibility – Can the roof support an overload charge due to the solar panels? It is necessary to check this point with the architect/building company. In general, it is necessary to count an overload of 15 to 25 kg/m2 for a solar power plant. Another important point is the current state of the electrical connection. Is it compatible with current regulations (TAB)? Your electrician will have to verify this point upon the appointment. You shoudl contact Klima Agence for any questions related to energy renovation ( www.klima-agence.lu).
Profitability – Sudstroum would recommend its customers to obtain several quotes before signing it.
Authorisation – The customer must obtain the agreement of the municipality ( Police des bâtisses, urbanisme ) before carrying out the work.
Connection Request -In Esch/Alzette: The electrician must make a connection request to Sudstroum (Demande-de-raccordement-word-13.09.2024.pdf)
The customer must conclude a buy-back contract with the network manager in the event of partial/total injection of production.
Buyback contract with negotiated rate with a supplier: Waiver of the guaranteed injection rate for the lifetime of the power plant, self-consumption mode for the entire lifetime of the installation.
15-Year Guaranteed Price Buyback Contract: Fixed remuneration for 15 years, based on the installation’s power output (kWp) and the year of the first injection. Offered exclusively by Sudstroum in the Esch-sur-Alzette area. Self-consumption is compatible with the guaranteed price.
Contact us to receive a buyback offer for your solar electricity. Simply send us an email to photovoltaique@sudstroum.lu specifying the installed capacity of your power plant and your grid connection and usage contracts with the network operator.
Please send your query to photovoltaique@sudstroum.lu specifying:
– “Notification de fin de travaux “signed by the electrician
– Installed capacity of your power plant
– Commissioning date
– Connection agreement and network operator’s usage agreement
Your solar plant is up and running, and you’re considering switching power suppliers. Sudstroum offers electricity buyback contracts with a negotiated rate in Luxembourg. Please address your request to photovoltaique@sudstroum.lu, specifying:
– Notice of completion of work signed by the electrician (“Notification de fin de travaux signée par l’électricien”)
– Installed capacity of your plant
– Commissioning date
– Connection contract and usage contract from the grid owner
Sudstroum does not accept buyback contracts with a guaranteed rate outside the territory of Esch-sur-Alzette.
When concluding connection and usage contracts, you will need to indicate the type of desired rate.
Sudstroum offers a feed-in contract under certain conditions(1). The applicable rate corresponds to a percentage of the MW Solar Netztransparenz price (( Netztransparenz > Erneuerbare Energien und Umlagen > EEG > Transparenzanforderungen > Marktprämie > Marktwertübersicht)). This is a monthly price quoted on the German stock exchange for renewable energy.
For more information, please send us an email to photovoltaique@sudstroum.lu specifying:
– Installed capacity of your power plant
– Connection contract and usage contract from the grid operator
(1)Give up the guaranteed rate for the lifetime of the plant. Solar plant with lifetime self-consumption mode
The guaranteed feed-in tariff corresponds to a fixed payment for 15 years, based on the installation’s power output (kWp) and the year of the first injection. This tariff is not indexed. Since 2021, you can also consume the energy produced by your installation. An additional meter must be installed for any photovoltaic system with a guaranteed tariff.

A “plug & play” type solar plant corresponds to one/two sun cells with up to 799 Wp inverter power. No connection request needs to be addressed to the grid owner. The plug & play plant is connected to a domestic socket.

The We Share Energy software allows you to view your consumption or production values and compare them with those of your neighbors or friends, in order to then share electricity as best as possible.
The We Share Energy software allows you to view your consumption or production values and compare them with those of your neighbors or friends, in order to then share electricity as best as possible.
– The locally produced energy is first consumed as much as possible by the occupants of the building to which the power plant (in the illustration below, a photovoltaic power plant) is connected (individual self-consumption or AC, level 1).
– If there is still excess energy from the photovoltaic power plant, it will be shared with the members of the CEL (level 2).
– If the needs of all members of the L-CE are met and there is still excess energy from the photovoltaic power plant, this is shared with the N-CE (level 3).
– Any remaining energy from the photovoltaic power plant, it is then injected into the grid (level 4).
Customers who plan to self-consume their photovoltaic production must subscribe to one of the following plans.
A single user connected to the main/house meter and the solar plant.
– Solar plant is connected to a new meter.
– Low or medium voltage grid connection
– Exempt from grid fees, compensation fund, and electricity tax on self-consumption
– User is not a legal entity
– Surplus energy can be shared with other energy communities (ACR/AC1/CEL/APS/CER)
– No need to complete a sharing agreement
If you want to share electricity with your neighbors, you must become a member of an AC. To do so, you must sign an agreement with your grid manager. This agreement defines the rules for sharing electricity. If you wish, you can leave an AC.
If you want to share your electricity with other people outside your home, you must become a member of a CE. To do this, you must sign an agreement with your network manager.
