Control strategies for energy enhancement of discontinuous GPS tracking PV system under varying weather conditions

Energy harvesting systems have been piloted in this experimental paper. The proposed system uses ten-watt solar panel for static base photovoltaic (PV) and a two-orientation sun follower system. Application of GPS (global positioning system) in sun following arrangement ensures the best potential output power from solar radiation. By tracing the sun’s trajectory across the sky over the course of the day, the GPS-based two-orientation sun following system has been able to record maximum sunlight intensity from 6:00 to 18:30 solar time. The two-axis sun follower system with GPS has a higher engrossed power than the light-dependent resister (LDR). Two-axis GPS, LDR tracker and the static base panel produce the average energy of 146.7 Wh, 82.45 Wh and 42.79 Wh on a sunny, hazy and rainy day, respectively. The solar panel used here is flexible, which uses 15 \(^{\circ }\) ${}^{\circ }$ of step tracking to reduce system power consumption. The experimented result of 2021 states that the average amount of energy produced by the two-axis-GPS sun following system was 4.021754 Wh/day, which is 45.85% and 14.93% more than the average amount of energy produced by the static base and LDR base PV system, respectively. This novelty emphasizes system with minimum power consumption to generate maximum power. Here, the GPS will provide the extreme accurate trajectory of sun path. The flexible panel with lightweight reduces power consumption of tracker. And finally the 15 \(^{\circ }\) ${}^{\circ }$ or discontinuous tracking reduces the power consumption as used in continuous tracking.
