Dual Axis Tracking System with a Single Motor

The main direction in the use of solar energy conversion systems is to improve their efficiency by using dual axial tracking systems. The energy required for positioning the photovoltaic platforms is significant due to the complexity of constructive solutions of dual axial tracking systems, which incorporate one driving source for each axis, and of the control systems. Thus, the interest in research, innovation, production and implementation of tracking systems increased. This paper presents a new tracking system for photovoltaic platforms actuated by a single rotary electric motor and the tracking method used in order to maximize the energy production.
