What they do

The solar park was installed in July 2011 and purchased by the co-operative in October 2012 following a community share offer for £5.8 million. The plant covers 12 acres and generates enough electricity to power 1,400 homes. That’s equivalent to every home in the nearby villages of Watchfield & Shrivenham. Read more
