SolarWindow Technologies has developed a glass window that can generate power from sun rays.

Intended for use as modules in commercial developments, the windows can be applied to all four sides of tall towers in order to generate clean energy.

Unlike conventional units that can only perform in natural light, SolarWindow modules can also derive energy from shaded and artificial light.

This innovation means that the system outperforms existing solar modules by as much a 50-times, when installed on a 50-storey building.

SolarWindow Technologies president and CEO John A Conklin said: "It’s a great way to see how, exactly, we can turn the countless acres of glass on offices, hotels, and commercial buildings into clean power generators."

"We can turn the countless acres of glass on offices, hotels, and commercial buildings into clean power generators."

Commercial buildings account for more than one-third of the total power used by the US. To aid green energy production, the firm is manufacturing proprietary windows for around five million skyscrapers, tall towers and commercial buildings in the US, it said.

For power generation, the technology uses transparent glass tinted in a high-demand colour and framed in aluminum. This type of material is commonly used for commercial tower developments, as it is popular with architects and developers.

A single installation of the SolarWindow technology has been estimated to help offset 2.2 million miles of vehicle pollution, which is at least 12-times more than traditional solar installations on rooftops.

While modern rooftop photovoltaic systems can lower carbon emissions levels equivalent to 20 to 70 acres of forest, the SolarWindow technology represents a reduction of 770 acres.
