Could Tesco Extra Portwood, Stockport go solar?
Standing on its own at Portwood in Stockport, this Tesco Extra superstore has a large flat roof of around 9,800 sqm. We measured about 4,500 panels, roughly 1.8 MW — enough for an estimated 1.2–1.4 million kWh a year, in the region of 480 homes. With the store's own daytime load underneath, a survey would confirm what's practical to fit.
