The Cologne-based group Wattner, which specialises in solar and infrastructure assets, has commissioned Germany's largest rooftop solar system on the roofs of the automobile manufacturer Opel, a subsidiary of General Motors, in Ruesselsheim.

Five of the company's rooftops will be used to realise a project with a total installed capacity of 9.2 MW. The feed-in of that electricity from the rooftops directly into the production facilities means that there will be no energy losses incurred through cable routing. "The project highlights the environmentally conscious and sustainable corporate philosophy of Opel," according to Ulrich Uhlenhut, managing director of Wattner AG.

Wattner commissioned EWT SolServ GmbH, also a partner of Adam Opel AG, with the construction of the installation. Approximately 40,000 solar modules and 500 inverters feed renewable energy directly into Opel's corporate grid.

The cost of the Ruesselsheim project will amount to approximately €20 million. Wattner has also just secured two more attractive solar parks, with a similarly high combined capacity and investment volume: Fürstenwalde near Berlin, with a current capacity of 3.15 MW and an investment volume of €6.5 million, and the solar power plant in Harbke, Saxony-Anhalt, currently with a capacity of 4.9 MW and an investment of nearly €10 million.

Wattner has a global target pipeline of 500 MW of solar projects by 2012 in countries across Europe, North America and emerging markets.
