Solar Powered Bird Repeller The Bird Repeller is a solar powered bird deterrent that uses continuous motion to prevent large pest birds such as seagulls, pigeons, and crows, from landing. Rotating “arms” mounted on top of the unit sweep birds off of streetlights, balconies, boats, AC units and more! The two adjustable “arms” cover up to 5 ft in diameter by turning continuously at 30 RPM’s. A solar panel powers a heavy duty, brushless motor which will store energy. The Solar Bird Repeller is portable, and can store energy to keep it lasting into the night.
