Giant solar plant for Sears Tower
Sears Tower (or Willis Tower), is all set to don its green attire by integrating a pilot solar electric glass project on the south side windows of its 56th floor. This in effect will transform the skyscraper into a giant solar plant with 2 MW capacity, which is almost equal to the power generated by a 10-acre field of solar panels.
The high-profile project on the south side of the 56th floor will replace the windows with a new type of photovoltaic glass developed by Pythagoras Solar which preserves daylighting and views while reducing heat gain and producing the same energy as a conventional solar panel.
This innovative product can be simply described as a solar window. It combines energy efficiency, power generation, and transparency in a standard form factor that can be easily integrated into conventional building design.
“Pythagoras Solar’s Photovoltaic Glass Unit (PVGU) uses patent-pending optical technology, high-efficiency silicon, and advanced materials to provide the industry’s first highest-transparency and highest-density PV power generation in a standard double-pane window form factor, known in the industry as an insulating glass unit, or IGU. The PVGU leverages the modularity and ease of installation of the IGU while controlling direct solar radiation and providing greater transparency to further increase the energy efficiency gains through reduced heating/cooling and lighting costs.”
