Photovoltaic system combines culture with sustainability

The Langmatt Museum is producing solar power as part of its complete refurbishment. On the roof of a newly constructed glass pavilion, a photovoltaic system from Regionalwerke Baden will supply the museum and the complex with sustainable energy in future.

In future, the Museum Langmatt will produce renewable solar power with a 40/45 kilowatt photovoltaic system, enough for the annual consumption of 15 to 20 flats. The grey in-roof modules were installed by Regionalwerke Baden. According to a statement from Regionalwerke, the modules were in keeping with the spirit of the museum, which was built by Sidney Brown, co-founder of the technology group ABB: “Contemporary technology is perfectly compatible with the historical spirit of the Langmatt,” says Markus Stegmann, Director of the Langmatt Museum.

The PV system is installed on the roof of the newly installed glass pavilion in the park, which was built as part of the complete renovation and expansion of the complex. “The pavilion is intended for readings, concerts and aperitifs for group visits,” says Stegmann.

While the PV modules have already been in operation for a month, the renovation work is not expected to be completed until next year. The art nouveau villa Langmatt, which now houses the museum, was built around 125 years ago on behalf of the art-loving industrialist couple Brown. The museum therefore houses an important collection of French Impressionists such as Claude Monet and Pierre-Auguste Renoir.
