Solar boom in Altenburger Land: 5th place in the Thuringian ranking!
The Unstrut-Hainich district and the Altenburger Land are relying on solar energy: important developments, systems and rankings for 2025.

Solar boom in Altenburger Land: 5th place in the Thuringian ranking!
Something is happening in the field of solar energy in Altenburger Land: Currently, over 180,000 kilowatt hours (kWh) are being generated from solar systems. Although this number is rather average compared to other Thuringian districts, it shows a clear upward trend, as the use of photovoltaics has increased over the last ten years. How lvz.de reports, Altenburger Land is currently in fifth place in Thuringia's solar ranking with a total of 183,673 kWh. Four years ago the region was in first place, but has been overtaken by stronger districts such as the Unstrut-Hainich district and the Wartburg district.
Overall, Thuringia is generating a little less than 2.9 million kWh from solar systems this year, which is about 170 percent more than a decade ago. Interestingly, in Altenburger Land over 50 percent of this energy comes from open-space systems, and that is 101,000 kWh. Rooftop systems generate around 78,000 kWh, while other types of solar systems generate around 4,000 kWh.
News from the Posterstein solar park
An exciting development in Altenburger Land is the construction of a new solar park in Posterstein. The official start of construction was heralded on March 11, 2025 with a ceremonial groundbreaking ceremony. A total output of 49 megawatt peak (MWp) is planned, which will generate around 50 million kWh annually - enough electricity for around 14,000 four-person households. State parliament member Christoph Zippel and mayor Stefan Jakubek have already attached symbolic importance to this project, and the municipality hopes to generate annual income of around 100,000 euros from this project abg-net.de reported about it.
The construction work is scheduled to be completed by September 2025, and the solar park is also scheduled to be commissioned this year. Agricultural land is being repurposed, but at the same time space is being made for a flowering meadow that benefits local flora and fauna. A small celebration to mark the opening of the park is already being planned to introduce citizens to the unique technology.
The development of solar energy in Thuringia
The boom in solar energy in Thuringia is obvious: as of December 31, 2024, there were already around 100,000 solar systems in the Free State, which corresponds to a significant increase compared to the previous year. Around 12,700 new systems were put into operation in the first half of 2024. Interestingly, demand for balcony PV systems has particularly increased, increasing by 5,843 new units last year and now increasing to around 14,000 balcony systems in Thuringia. On average there are 47 photovoltaic systems per 1,000 inhabitants thega.de finds out.
Solar energy in Thuringia is not only developing quantitatively, the feed-in is also significant: the installed capacity of the PV systems is now 2,801 megawatts and covers 23 percent of the electricity consumption in the Free State.
Overall, it can be seen that the Altenburger Land and Thuringia are heading towards a sustainable future through the further development of solar energy. With projects like the large solar park in Posterstein, the region is heavily involved in the debate about renewable energies and shows a flair for innovative approaches to energy generation.
