Solar energy is a very notable and unlimited source of energy. The usage of solar energy main issue is the difference in readiness of solar energy happens day-to-day due to the sun's movement changes throughout the year. The dissimilarity in accessibility arises daily as of the cycle of night and day and the season change due to the earth?s rotation with our star which is the sun. In order to achieve the maximum sun irradiation, the solar panel has to be positioned correctly throughout the day. Creation of a simple, low cost solar tracking system with emphasizing on a two-axis solar tracking system with automatic detection using Light Dependent Resistor (LDR). The system is to track the sunlight and switch its location appropriately to exploit the maximum power yield. Comparison of the efficiency on the two-axis system with a fixed solar panel system will be probed into. Tracking system consists of Light Dependent Resistor, Arduino Nano microcontroller to drive the direct current servo motors and gearing positioning with supports structure. The direct current servo motors are employed in order to position the solar panel to ensure the solar irradiation is able to be maintained aligned with the solar panel throughout the day. Water spray system is used for cooling system that employs DC pump with the help of RTC sensor which detects the panel temperature with ambient air temperature. The difference will allow the pump to send the water onto the panel.
