Solar energy is one of the most effective resources because of its cheap source and its reliability to sustain. The best way to attain the maximum possible efficiency from solar panels is to use tracking devices. Solar tracking will contribute significantly to increasing the efficiency of energy collection from the PV panels. Trackers can either be the single- or dual-axis. In this work, we have presented the designing and performance analysis of the dual-axis solar tracking system in comparison to the fixed panel system. We have determined the output power generated by a dual-axis solar tracking system is more than the fixed panel system. The outcome of the dual-axis solar tracking system has been analyzed and compared with the fixed panel system has been highlighted and it has shown better performance in terms of voltage, current, power and battery charging capabilities. Dual-axis trackers give more energy as it tracks sunlight in both the direction. Hence it is more efficient than fixed panel.
