Here is part of the press release in September
Company President and CEO, Mr. John A. Conklin, revealed that the application of SolarWindow™ to exterior glass surfaces of commercial towers could generate energy savings several-fold greater than today's rooftop solar systems during his introduction of New Energy's SolarWindow™, the world's first see-thru, spray-on technology of its kind.
In commercial applications, such as the building facades of office towers, engineers conservatively estimate that installation of New Energy's SolarWindow™ can generate more than 300% energy savings over conventional rooftop solar systems. Key to maximizing energy production, SolarWindow™ can be applied to the extensive glass surfaces on commercial skyscrapers, an important advantage over conventional solar systems confined to installation on space-prohibitive rooftops.
By way of example, engineers modeling a 40-story building, similar to Tampa's landmark "100 North Tampa," estimate annual cost-savings of $40,000 to $70,000 when installing New Energy's SolarWindow™ to exposed window facades. In contrast, mounting today's popular poly-crystalline silicon modules on the rooftop produces only $20,000 in energy savings per year.
