A unique solar-powered, pulley-assisted, simultaneously-and-oppositely-movable-top-and-bottom-weighted-bracket umbrella has movable weighted rib and strut brackets for eliminating the umbrella-operating roughness by having predetermined weights to increase the gravitational forces exerted thereon when they are moving up and down. The umbrella further has an electric motor, a solar panel to collect energy from the sun light, and a circuit-board control center for converting the solar energy into electricity and for regulating the operation and energy management of the electric motor. The umbrella further has lights, a threaded spindle rotated by the motor, pulleys for raising and lowering the weighted rib and strut brackets in opposite directions at the same time to reduce 50% of then travel distances and 50% of their weights, an external electricity storage, and a remote control device for remotely operating the motor and lights.
