According to the solar industry, more new solar systems to generate electricity and heat were built in Germany last year than ever before. More than a million new systems have been installed, the German Solar Industry Association (BSW) reported on Tuesday in Berlin. The so-called balcony power plants play a large part in this. In 2023, around 270,000 so-called plug-in solar devices were put into operation in Germany. That is four times as many as in 2022.
According to the Federal Network Agency, systems with a peak output of around 14 gigawatts were put into operation on roofs and open spaces when generating electricity from sunlight, the association also reported. This is 85 percent more than in the previous year 2022. Half of the newly installed solar power output in 2023 was in the home segment, according to the BSW.
Solar systems on open spaces accounted for around 31 percent and systems on commercial roofs around 18 percent. “Due to their low specific output, the large number of plug-in solar devices did not account for two percent of the newly installed PV output,” emphasized BSW Managing Director Carsten Körnig. There are now around 3.7 million solar power systems installed in Germany. They would have generated around 62 billion kilowatt hours of electricity in 2023, covering around twelve percent of German electricity consumption.
“We expect a sustained solar boom in 2024”
The industry association expects demand to remain high in 2024. He justifies this with continued rising electricity prices and attractive funding conditions. “We expect a sustained solar boom in 2024,” explained Körnig. In order for the growth targets to be achieved in the following years, the reduction in bureaucracy must not come to a standstill. Further measures to speed up the process are required in order to upgrade the electricity and heating networks more quickly.
In 2024, more than 1.5 million property owners planned to install a solar system on their roof, the BSW reported. For this projection, the association relies on a representative survey conducted by the opinion research institute Yougov among around 1,000 property owners in mid-December. According to this, 69 percent of owners of residential properties with suitable roof areas can imagine building a solar system on the roof area. “16 percent are already planning this in the next twelve months,” it said.
Specifically, in the home segment with roof systems with a PV output of up to 30 kilowatts, the association expects demand in 2024 to be of a similar magnitude to 2023. Last year, PV roof systems with a total of seven gigawatts of peak output were installed in this segment. However, the BSW expects market growth for PV systems on commercial roofs and open spaces.
