dhp brings its largest folding solar roof to Stuttgart
The Grisons-based company dhp Technology is building its largest folding solar roof to date in Stuttgart. By spring 2026, the main sewage treatment plant will be equipped with 5280 modules on an area of almost two football fields. With the electricity from renewable energies, the sewage treatment plant will cover 11 percent of its own needs.
Zizers-based dhp Technology is building its largest folding solar roof to date for the main sewage treatment plant in Stuttgart-Mühlhausen. By spring 2026, 5280 modules are to be installed on an area of 17,000 square metres. According to a statement, the system with an output of 2745 kilowatts peak is the largest folding solar roof installed by dhp.
With the Bündner technology, the sewage treatment plant in Baden-Württemberg’s state capital can generate up to 11 per cent of its annual consumption itself. In the medium term, a value of 18 percent is targeted.
According to the plans of the Stuttgart municipal wastewater treatment plant(SES), solar modules will be installed not only in the aeration basin in the north of the 25-hectare plant, but also in the area to the south, which is of a similar size. According to SES, the investment will save more than 900 tonnes of carbon dioxide.
