Abstract
An electromechanical solution for 2 axis solar tracking is disclosed that is suitable for application with a single solar heat, hot water or photovoltaic panel. 3 points of contact are arranged in a triangle on the back of the panel with 2 points of contact connected by linear actuators and flexible couplings. The third point of contact is a spherical bearing at the base of the panel. The actuators are independently adjustable in length by using electric motors according to a microprocessor program. In this way, 2 rotary axes of motion with limited angles are achieved which can orient the panel to the sun with minimal hardware. Since only one solar panel is being controlled the mechanical force required is minimized.
