Company to Launch Photovoltaic IG Unit

May 21, 2010

A company with operations in the U.S., Israel and China plans to commercialize what it calls "the industry’s first energy efficient, transparent and high power density photovoltaic glass unit."  Pythagoras Solar says its technology combines energy efficiency, solar power generation and appealing aesthetics into a single glass unit for use in curtain walls, skylights and windows in the second half of 2010.  

“Our new PVGU technology finally bridges the gap between energy efficiency and energy generation–enabling the architecture, engineering and construction sectors to accelerate the deployment of cost-effective distributed power generation and to advance aesthetically-pleasing net zero energy buildings,” says Gonen Fink, Pythagoras co-founder and CEO. “Our partners across the value chain are responding very positively to the combination of economic, environmental and aesthetic benefits.”

The new technology combines optics, high-efficiency crystalline silicon, advanced materials science and simulation software to create a highly efficient photovoltaic glass unit. Unlike existing BIPV products, curtain walls, skylights and windows using the glass product simultaneously block solar radiation; concentrate sunlight and convert it into solar power; and deliver a high level of transparency for optimal daylighting and aesthetics, the company states.

A 2007 start-up, Pythagoras Solar reports it has established formal relationships with Arkema, China Sunergy and Flextronics, all of which will help it quickly scale its operations as it prepares for commercial production and distribution.

“We are very excited to partner with Pythagoras Solar on the production of the company’s revolutionary PVGU products," says E.C. Sykes, Flextronics president. "Our early involvement in the design process will not only help the team to optimize the product in the early stages of development, it will also help to leverage Flextronics’ scalable and repeatable manufacturing process. We are always happy to provide our industry leading clean tech solutions and services to companies such as Pythagoras Solar that enable green applications which meet the high quality requirements of the solar industry and are aesthetically pleasing.”

“Pythagoras Solar’s approach to BIPV is unique and overcomes barriers to adoption for the architecture, engineering and construction community,” says Meir Ukeles, partner, Israel Cleantech Ventures, an investor in the company. “As the solar PV market matures, we expect that BIPV will represent a much larger portion of new distributed generation installations given the volume of available square footage for PVGU installations.”
