Grid operator Fluvius this week published the official registration figures for all of Belgium. The total stands at approximately 8,000 devices — but the actual number is presumably much higher, as not everyone is required to report.

Why is the plug-in battery performing so well?

The smart meter is advancing in Flanders, and with it, the net metering system is disappearing. Many households with solar panels are looking for a smart way to store their self-generated electricity instead of putting it on the grid for free. The plug-in battery is the perfect and affordable solution for this.

Belgium has only just begun

If you compare the Belgian figures with our neighboring countries, it becomes clear that we are still at the beginning. In Germany, approximately 435,000 plug-in solar panels were registered in 2024 alone, with an estimated total park of 1.5 to 4 million devices. In France, the count stood at more than 66,000 at the end of 2025. Growth in Belgium is coming — and that growth is already visible.
