Dual Axis Tracker for Photovoltaic Panel

Abstract

Main challenge of solar-tracking systems are the sunlight detection, providing position and delay of PV movement, designing control module for low consumption dc servo motor(s). Objective of this paper is designing and implementing automatic control for detecting maximum solar light to a solar panel. The two-axis solar tracker is used for optimizing conversion of solar energy into electrical energy, at cost of the mechanical and the maintenance need, for the best efficiency. The hardware development, two dc servomotors are adjusted which is controlled by drive module moving panel by using four Light-Dependent Resistor (LDR) to provide the analog signals; the signals are processed by ATMEGA328P micro-controller with Arduino.

Dual-axis Solar Energy Tracking and Monitoring System with Arduino as a Microcontroller

“…The result shows that the proposed system produced higher solar power as compared to the system without tracking mechanism. In [12], the role of a gearbox is highlighted as a speed-reducing gear to further increase torque of mechanical movement as well as the accuracy of solar tracker positioning towards solar direction. The gearbox is embedded in two dc servomotor outputs.…”
