Station expected to produce 250,000kW hours per year

Stillwell Avenue subway station in Brooklyn, N.Y., was recently reconstructed to become the city’s first solar-powered train terminal. RWE SCHOTT Solar manufactured the 76,000-square-foot solar roof, which is expected to contribute approximately 250,000kW hours a year to the station’s non-traction power needs.

The arched solar roof consists of 2,730 glass laminate, building-integrated PV panels that are made of clear glass and strips of thin-film amorphous silicon materials. The panels cover the full width of the station and offer weather protection for travelers as well as the station facilities. The panels are the largest, thin-film panels in the world and require less framing, which reduces installation costs.
