John Muir Health installed a photovoltaic solar system on the roof of the Walnut Creek Medical Center’s parking garage. The system will produce approximately 580,000 kilowatt (kWh) hours of power annually and will save John Muir Health approximately $1.4 million in energy costs over the life of the system.

The installation will also help realize goals in greenhouse gas reduction set by the City of Walnut Creek and the State of California.
