Abstract: An unmanned snow prevention and removal system is provided which prevents or eliminates the accummulation of falling snow in selected ingress and egress passageways on the ground, such as sidewalks and driveways. An array of disposed parallel linear cooperative panels is provided covering such passageways upon which the accumulated falling snow is caught, and is subsequently intermittently and automatically thrown off such panels on wither side of their respective lengths by their sweeping motion through an arc of a circle from an initial near horizontal intersecting position by an electrical motor drive. Removal of accumulated snow from the panel array during their sweeping-throw and return motion as a result of the snow sliding downward of the panels is assisted by the provision of electrical heater elements disposed along the full length thereof and contained within the body of each panel which enables the accumulated snow to slide off the panel more readily.
