- Rooftop PV plant to be one of the largest in Berlin
- Power generation equals ca. 800 single-family homes
- ca. 80% used for on-site power, 20% fed into local grid
Swiss rail manufacturer Stadler’s German subsidiary is building a rooftop photovoltaic installation on its Berlin production facility. Using just over 7.200 modules from LONGi Solar, the largest module manufacturer worldwide, the array will cover 14.000 square meters on Stadler Deutschland’s assembly plant. Electrical and building engineering firm Sandmeyer GmbH, which is installing the project, expects it to be completed by the end of 2023. Stadler Rail AG is a leading global producer of rail vehicles.
Stadler rooftop PV will cover majority of Berlin facility’s electricity needs
The modules will generate 3,000 MWh electricity per year, enough to supply ca. 800 average single-family homes with their annual electricity consumption, making the installation one of Berlin’s largest solar power plants. The Stadler Deutschland facility expects to consume 80% of the electricity itself, while feeding the remaining 20% into the local grid.
Christian Keasler, Sales Manager DACH at LONGi Solar said: “We are very proud to support a solar installation of such a significant size in Berlin jointly with the long-time photovoltaic specialists Sandmeyer GmbH and Limes GmbH. The solar expansion in Berlin still has a lot of untapped potential, especially when it comes to harnessing the vast roofs of industrial and production plants.”
Sandmeyer GmbH’s managing directors, Timm Sandmeyer and Malte Sandmeyer, added: “For large commercial or industrial projects like Stadler Deutschland’s Berlin rooftop, we believe it’s essential for the installation to deliver the most reliable possible power. This facility must be able to depend on its electricity generation, so we work with premium products from LONGi Solar.
