The 500 kw solar array is being built in place on top of the largest building at the Harvard owned, The Arsenal. The Arsenal was used during the two world wars to manufacture field artillery, guns and ammunition.

The new array is expected to generate over 600,000 kw hours of electricity a year, just over 7% of the electricity used by the tenants. The energy consumed is enough to power over 30 homes, and is the equivalent of removing over 40 cars from our roads.

In addition, Harvard is installing two 10 kw wind generators on the Soldiers Field Park Garage, as well as solar thermal for two residential properties and smaller wind generators on top of Holyoke Center in Harvard Square.
