The Erlasee Solar Park, also sometimes called the Gut Erlasee Solar Park, is a photovoltaic power station located in one of the sunniest regions of Germany. On the former wine-producing Erlasee estate near Arnstein in Bavaria, in southern Germany, Solon SE has constructed what was, at the time of its construction, the largest trackingphotovoltaic solar power station in the world with maximum installed capacity of 12 MW. Just under 1,500 "SOLON-Movers" tracker mounted arrays convert sunlight into environmentally friendly power, generating as (ref?) much as the average consumption of the nearby town of Arnstein.
The plant cost £35 million (37 million euro, as of 23-12-2008) and covers 77 hectares of land.[dead link]
