Leipzig sets standards: Germany's largest solar thermal system!

Leipzig, Deutschland - In Leipzig, the construction of Germany's largest solar thermal system has taken a significant step. With today's date, July 11th, 2025, the last collector of the impressive facility was set up, which consists of a total of 13,200 collectors and is to achieve a peak output of 41 megawatts. taz.de reports that ....

The total area of ​​the system extends over 14 hectares, and in the future it will cover up to 20 percent of the heat requirement of Leipzig's 630,000 inhabitants. This is an important step for the city to cover your heat requirement free of greenhouse gas and implement the municipal heat plan.

progress in the energy transition

"In Leipzig-Lausen, the construction of the largest solar thermal facility in Germany begins," said Saxon Minister of State Wolfram Günther at the inauguration. This system is not only a technical masterpiece of the Leipzig Stadtwerke and Ritter XL Solar, but also an important part of the Saxon energy transition. It integrates various renewable energies, including green hydrogen, wind energy and photovoltaics. The investment volume is around 40 million euros, of which 16 million euros are funded. l.de adds that ...

An intelligent system that controls the flow speed of the water depending on the sun's rays will operate the system efficiently. The heated water is then led through district heating lines to customers. The completion of the system is scheduled for the end of 2025, with complete heat supply from 2026.

efficiency and environmental friendliness

solar thermal energy, in contrast to photovoltaics, produces heat from solar energy and is considered one of the most efficient renewable heat sources. Studies show that in many cases solar heat systems are more economical than fossil-fueled systems. About three times more energy can be used in solar thermal energy than in photovoltaics per hectare. These systems are not only a financial profit, but also an environmentally friendly solution, as they contribute to saving oil and gas and avoid emissions.

Beyond the construction, the area is designed to be natural after the construction period. Blühwiesen, fruit trees and mixing hedges are planned, among other things. A flock of sheep is used to maintain the surfaces, which further underlines the environmentally friendly approaches.

In summary, it can be said that Leipzig is going to a green future. This large solar thermal system is not only a technical innovation, but also a model for the implementation of climate protection measures in urban areas. With solid planning, intelligent technologies and a clear vision, the city will soon be able to meet the heat requirements of its citizens.
