Increase in the number of balcony power plants in Saxony

The number of balcony power plants in Saxony rose by almost a quarter (22.5 percent) in the first half of the year. At the end of June, 55,842 of these systems were registered with the Federal Network Agency - 10,253 more than at the end of 2024. The actual number is likely to be slightly higher, as there is a one-month deadline for late registrations and not all systems are registered despite being mandatory. With a figure of 26.5 installations per 1,000 households, Saxony is above the national average (just under 25).

With regard to Germany as a whole, the million mark has now been broken for balcony power plants. At the end of June, 1,009,390 of these systems were registered. This means that the number grew by more than 220,000 in the first six months, which is roughly the same level as the previous year.

Carsten Körnig from the German Solar Industry Association also does not see any significant slowdown so far: "Plug-in solar devices continue to enjoy great popularity. We expect demand to remain high." The main drivers are the legal simplifications that were passed under the last German government and the fact that prices for the systems have fallen in the meantime.

In addition, the fact that more and more well-known retailers have recently started stocking the appliances could contribute to the boom. "This should strengthen the perception that balcony power plants have arrived in the middle of society," says Körnig.

Highest density in Lower Saxony

Surprisingly, the most balcony power stations can be found in the most populous federal states of North Rhine-Westphalia and Bavaria, with a good 200,000 and 150,000 respectively. However, if the number of power stations is compared to the number of households surveyed by the Federal Statistical Office in order to make a better comparison, Lower Saxony and Rhineland-Palatinate are in the lead. There are just under 34 and just under 31 plants per 1,000 households respectively.
