Design of Automatic Switching System and Data Acquisition on Mobile Hybrid Solar Tracking System for Stand Alone Small PV with Reflector

A hybrid solar tracker is required to maximize the energy efficiency of solar power. This system is inaccurately monitored and is not user-friendly managed. A simple and low-cost data acquisition system is needed to successfully designed for data acquisition and automatic switching on the hybrid solar tracker. The result reveals that the sunlight intensity with 3.5 volts threshold voltage becomes the switching parameter on hybrid solar tracker which affects the LDR voltage. The maximum distance of data transmission systems using telemetry 3DR module for blocked location is 120 meters, while the unblocked location is 350 meters. The existence of the automatic switching on the solar tracker may increase the output efficiency of the hybrid solar tracker PV with reflector can reach 51.56% compared to the fixed PV, with an energy deviation of 183.88 Wh. The energy generated by the tracker PV is 540.47 Wh, while the energy consumption of the main component is 71.68 Wh. Therefore, the energy that can be saved is 468.79 Wh.
