Microcontroller-based solar energy tracker system with single axis orientation


Chiagunye Tochukwu, Somtoochukwu Ilo, Eze Aru Okereke

Maximizing the conversion of sunlight into electricity through the use of photovoltaic solar cells has led to the operation of solar power generating systems below its expected efficiency benchmark. The problem posed thus is to implement a system that is capable of improving solar power production by 30-40%.In this paper a microcontroller based sun tracking system is designed to ensure that the solar panel is always parallel to the sun for maximum energy output. Microcontroller is used to implement the control circuit which in turn positions a motor used to orient the solar panel optimally.Light intensity detecting sensors were used to receive light rays and the signal processed through a microcontroller to rotate the solar panel towards the side with maximum intensity using the turning mechanism of a 5.2 degrees unipolar stepper motor. Thus, this tracking system is designed to automatically follow the sun and from the input received, it can actuate some mechanism to position the solar panel where it can receive maximum sunlight to produce more output energy.
