Pythagoras Solar, a provider of building-integrated photovoltaic (BIPV) products, has planned to commercialize photovoltaic glass unit (PVGU).

The company said that its new technology combines energy efficiency and solar power generation into a single green building material — a solar window. The PVGU products will be available for curtain walls, skylights and windows in the second half of 2010.

Pythagoras Solar has also established formal relationships with Arkema, China Sunergy and Flextronics, all of which will help Pythagoras Solar to scale its operations as it prepares for commercial production and distribution.

Pythagoras Solar leverages a combination of patent-pending optics, crystalline silicon, advanced materials science and simulation software to create a PVGU.

Unlike existing BIPV products, Pythagoras Solar curtain walls, skylights and windows 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 claims.

The company said that its products offer triple-value benefits by combining the energy efficiency benefits of an insulating glass unit, the shading and lighting benefits of patent-pending optics, and high efficiency solar power generation, which combined offer architectural adaptability and increased real estate value.

Gonen Fink, co-founder and CEO of Pythagoras Solar, said: “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.

“Our partners across the value chain are responding very positively to the combination of economic, environmental and aesthetic benefits.”
