Could Great Western Hospital go solar?

On Marlborough Road in Swindon, the Great Western Hospital has run since 2002, and its large roof expanse covers around 12,400 square metres. We estimate that could carry roughly 1.7 MW of solar, close to 4,400 panels, for an estimated 1.5 to 1.8 million kWh a year in Swindon's roughly 1,030 sun hours. An acute hospital uses power at every hour, so most would be spent on site. Theoretical figures.
