The M&S distribution centre at Castle Donington handles all their online sales. It’s a massive building with a 20 acre roof most of which is going to be covered with 24,320 250w solar panels. These will generate over 6 MWp of power. The system was designed by http://sbcrenewables.com so if you have the roof space that’s who to get in touch with. The roof was 30m high and it was great being up there. I’ll be back again to photograph the finished job. The photographs below show the work underway.
