EC smart windows can be darkened and brightened as desired with the touch of a button with minimal maintenance, and can be self-powered by solar photovoltaics. They allow full control of visible light from outside, thus reducing the dependency on indoor lighting systems, and simultaneously block infra-red energy from entering the room, thus reducing the dependency on air-conditioning systems. We believe our EC smart windows will make an impact in regions with high solar irradiance, such as the Indian subcontinent, by providing a means for managing indoor lighting and temperature to further improve the energy access and welfare of local communities.
