Since Community Energy Birmingham installed solar PV in 2012, Ackers Adventure has halved its use of grid electricity at its ABC administration block,. The reduction is similar to the output from the solar array, meaning that virtually 100% of the electricity generated from the solar panels has been used in the office building,. There is still vacant space on the roof, and it was built with a south-facing slope that offers the ideal opportunity to add more panels, which we intend to do later in 2015.
