Spire Corp. (Bedford, MA) announced that Spire Solar Chicago has installed 50-kW solar electric systems on each of the roofs of three major Chicago museums: the Art Institute of Chicago, Mexican Fine Arts Center Museum, and Chicago Historical Society.
These photovoltaic (PV) systems can deliver about 180 MWh annually — enough electricity to power up to 30 homes. Together with the 49-kW Field Museum of Natural History PV system, completed by Spire last June, these installations are said to be the largest solar projects in Illinois.
