Chicago’s Sears Tower is set to become a massive solar electric plant. At first, in this pilot project solar electric glass will be installed on one floor on the south side of the building. Windows will be replaced with a new type of photovoltaic glass which preserves daylight and views while reducing heat gain and producing the same energy as a conventional solar panel. The project could grow to 2 MW in size — which is comparable to a 10 acre field of solar panels.
