Optimal Strategy for the Improvement of the Overall Performance of Dual-Axis Solar Tracking Systems

Solar Tracking Systems are useful to increase the generation efficiency of photovoltaic technology, mainly for concentration technology, where dual-axis is required on account of the high accurate alignment to the Sun. Even when there exists a strong relation between tracking error and energy effici...
