Solar panels shouldn''t cause any noise, including vibration. If your solar panels are experiencing shaky movement, this is primarily due to incorrect installation. Usually, most solar panels aren''t fixed directly on the roof. A racking system or a solar panel mount supports the panels on any surface, including the roof.
