Pythagoras Solar recently introduced an innovative way to power buildings – solar solar-panel windows, Ynet has learned. The startup company stated that seeing how buildings – especially skyscrapers – are the largest energy consumers in the urban sphere worldwide, they should be made to be as energy efficient as possible. Israeli Innovation News quoted Pythagoras Board Member Meir Ukeles as saying that idea came as a way to solve the problem of positioning large solar panels in crowded urban areas. The Israel-based Pythagoras aims to harness solar power to create self-sustaining green buildings, which will have reduced energy consumption. To that aim, the company developed the "Photovoltaic Glass Unit," which is said to be "a window that has solar cells encased between double panes of glass, which simultaneously saves and generates electricity."

Pythagoras Solar, which has a patent pending on the optical technology behind the Photovoltaic Glass Unit, further said it can generate enough electricity to power whole buildings. "The windows have a higher transparency level than regular windows and therefore optimize natural daylight inside buildings and increases the energy efficiency gains through reduced air-conditioning and lighting costs," Israeli Innovation News said. According to the report, the solar cells comprising the unit are adaptable and can be installed on nearly any kind of window, allowing them to be integrated into conventional construction processes. "The technology exists and the need is there. It’s just a question of fine-tuning and getting it on the market," Ukeles said. The technology, he added, is highly relevant for western and developing countries, which have high urban-density areas. Pythagoras Solar said that it already has several orders from companies in the United States, France and Japan. Follow Ynetnews on Facebook and Twitter
