Rooftop panels in Yonkers are among the largest solar installations in New York

Half Moon Ventures, a Chicago-based developer of solar and wind energy products, unveiled a rooftop solar installation the size of two pro football fields at i.Park Hudson, an office/industrial park in Yonkers, N.Y.

The solar project is expected to produce 1.2 million kilowatt hours of electricity a year, enough to power more than 120 homes and equivalent in reducing air pollution to taking 160 cars off the road.
