Abstract

This project presents the design and implementation of a prototyped for motor controller for solar energy optimum acquisition. This prototype can be divided into two major parts: the mechanical parts and electrical parts. Mechanical parts consist of bearings, motor shaft, vertical tower, holding block and base plate. The electrical parts include the charge controller, battery, photovoltaic panel, logic comparator and other electrical components. The combination of both mechanical and electrical parts is known as Balance-of-System. There are four modules in this design, which are sensor module, logic comparator module, signal output module and battery charging module. The photo sensor in the sensor module use to detect the light source and the signal will send to logic comparator module to examine the light condition. And the signal output module analyses the signal to rotate the solar panel. Lastly, the battery-charging module will activate as soon as the light hits on the panel. Two relays used in this system with each relay control only one direction for the motor rotation besides used to regulate the flow rate of electricity from the photovoltaic module to the battery and the load. From this initiative, simple power generation via photovoltaic technology can be utilized. With environment in mind, this small step will be significant milestone for the gradual change towards renewable energy resources.
