The present invention relates in general to a self-contained, solar-powered, self-regulating intelligent automated window treatment with increased energy efficiency. In particular, in accordance with one embodiment, the invention relates to a self-contained, solar-powered, self-regulating intelligent automated window treatment with increased energy efficiency consisting of: (1) a headrail with at least one solar panel, a rechargeable battery that is charged by the solar panel, and a motor that is powered by the rechargeable battery; (2) window shade fabric with one terminus of the fabric affixed to a tube and with the fabric wrapped around the tube and located within the headrail; (3) a smart bottom rail attached to the terminus of the shade fabric furthest from the tube with the bottom rail containing, at least one environmental sensor, at least one control button, at least one solar panel, and a rechargeable battery that is charged by the solar panel and that provides power to the environmental sensors and control buttons. The environmental sensors will provide information that will be used to determine when the shade motor should automatically raise and lower the shade with minimal effort from the user. In addition to relying on solar power, the automatic adjustment of the window treatment will allow for a reduction of energy consumption by the user by decreasing the need for artificial lighting, heating, and air conditioning.;In another embodiment of the invention, solar power stored in the rechargeable battery of the bottom rail may be transferred to the rechargeable battery-powered motor of the headrail.
