Pythagoras Solar, provider of the industry’s first solar window to simultaneously deliver energy efficiency, high power density and optimized daylighting, announced its participation and contribution of solar window technology to the Fraunhofer Center for Sustainable Energy Systems (CSE) Building Technology Showcase, a first-of-its-kind research and demonstration building for sustainable technologies in the City of Boston’s Innovation District.

• Pythagoras Solar is developing special semitransparent PV technology for solar windows.
• The main advantages of Pythagoras Solar’s Photovoltaic Glass Unit (PVGU) are optimized natural lighting and electricity generation.
• The PVGU units are based on crystalline silicon solar cells and special optics.

Pythagoras Solar is one of 35+ partners contributing a combined total of $2.7 million in advanced building energy technologies and services for the new “living laboratory.”

Pythagoras Solar’s Photovoltaic Glass Unit (PVGU), or solar window, provides significant and simultaneous benefits including energy efficiency, optimized daylighting, and high density solar power generation in a standard double-pane window form factor. This PVGU is easy-to-install, designed to meet advanced building codes and standards, can be optimized for a variety of uses and offers attractive economics with a typical ROI of 3-5 years. The first products are designed for curtain wall and skylight applications. Currently, Pythagoras Solar is shipping products for commercial projects and starting to deliver on a full pipeline of projects across the United States.
