RSi Unveils Power-Generating Transparent Photovoltaic-Glass Window

Solar windows are nothing new, but Rainbow Solar’s (RSi) new transparent photovoltaic-glass window looks like a big step for building-integrated photovoltaics. The window, which generates 80 to 250 watts of electricity, comes with some swanky extras— a built-in electrical privacy curtain as well as a new technology to convert the window into a light panel.

According to a recent study performed by the NTUST (National Taiwan University of Science and Technology), the new window has proven energy savings greater than 50 percent. RSi’s window can be built up to 9×9 ft in size, and uses battery technology with a lifespan of 55 years.

RSi claims that their technology could one day eliminate the need for electrical power plants. While I think that may be a bit of an exaggeration, the company’s solar windows are an easy, practical way for buildings to generate their own electricity.
