Who or what do I need to register with for solar panels? All energy suppliers have a joint website where you need to register. You do not need to contact your own energy supplier.
The overarching website for this is www.energieleveren.nl


It is a legal obligation according to European and Dutch laws and regulations to register your solar panels, and other energy generators. When registering, you also need to provide the serial number of the meter so that the energy supplier knows where energy is being supplied back to the grid. With the number of solar panels and other system parameters, the energy supplier can determine on a large scale what they need to take into account. They have their own algorithms for this.
Who can register?
You can do this yourself on the energieleveren.nl website. Your installer or network operator can also do this for you. The energieleveren.nl website explains how this works.
Why is this registration necessary?
There are more and more decentralized energy generators such as solar panels, wind turbines, biomass power plants, etc. The network operator must ensure the safety and availability of the electricity grid, and having a good understanding of the potential power generation is crucial. Many small solar panel systems eventually make up a substantial part of the total.

Together with weather forecasts, one can then estimate how much energy is being generated or how much energy needs to be supplied via other sources.
All in all, it is important for:
The safety of the electricity system. Promoting trade in electricity within the European Union. Integration of renewable energy sources. A more efficient use of the electricity network. What information do I need to provide when registering? In addition to your name and address, you will be asked for the capacity, brand, and type of the inverter.
When using micro inverters, you need to provide the total capacity: for example, if you have 12 solar panels of 345 Wp each with an Enphase IQ7+ inverter, the maximum output power of an IQ7+ is 295 W, or 0.295 kW. In this example, the total AC power you need to provide is 3.54 kW (12 times 0.295). The maximum output power of an IQ7 is 0.25 kW, the maximum output power of an IQ7X is 0.32 kW, and the maximum output power of an IQ7A is 0.366 kW. The brand here is “Enphase,” and the type is IQ7, IQ7+, IQ7X, or IQ7A, or a combination thereof.
The Watt-peak (Wp) value of the solar panel and the total system. You can find the above information on the invoice and/or agreement you have signed.
They also require the serial number of the electricity meter. If you already have a smart meter, that’s fine. If you still have an old Ferraris meter, your energy supplier is likely to come and replace it for free.
After registration, you can see that it is registered and visible to all electricity suppliers.
