Solar at 50 stories. Deutsche Bank boasts world's highest array

Posting in Cities

At 737 feet of the ground, the system isn't the bank's largest, but it is closer to the sun than any other commercial installation.

Financial services firm Deutsche Bank's newest solar array isn't the biggest commercial ever, but at more than 50 stories high, the company is touting it as the world's tallest.

The 122.4-kilowatt capacity array (pictured above) is on top of the bank's Americas headquarters building at 60 Wall St. in New York City. The building is 50 stories high, or 745 feet. The roof-top solar photovoltaic array was installed 737 feet off the ground on the south and east portions of the rooftop. (Vertigo anyone? I sure would hate to service these things.)

The new array is Deutsche Book's third completed solar project in North America. The bank also supports a 1.267-megawatt capacity installation at its Piscataway, N.J., office. (The project was completed in two phases, so the bank counts it as two projects.) Another project under way at the company's facility in Parsippany, N.J., is due for completion by the end of 2012. That installation is slated for 1.5 megawatts of solar capacity.

Deutsche Bank said "clean energy" sources contribute approximately 65 percent of its overall electricity needs worldwide, compared with 7 percent just four years ago. Aside from solar, Deutsche Bank has placed significant bets on wind energy that are detailed on its corporate sustainability information site.
