ON-ROOF POWER

“It’s not great if you’re a surgeon and you have to think about

getting the generator going.” - Paul Farmer

On a bright day, these panels are expected to produce more energy than

the hospital will consume.

Using 1,800 solar panels.

When fully operational, University Hospital is expected to be the

largest solar-powered hospital in the world that produces more than 100 percent of its required energy during peak daylight hours
