Project Title
Nowadays, photovoltaic (PV) systems have been being installed rapidly all over the world. However, the
installations typically employ a fixed flat-plate system, using pre-specified angles acquired by geographical
positioning. Hence, the power generated by PV systems decreases significantly, according to the variation of solar
irradiation in the progress of a day and the seasons in a year. In order to increase the solar power generation, this
paper proposes the design and implementation of a low-cost automatic dual-axis solar tracker system. The
tracking system is designed as a closed-loop control based active tracking system, employing Light Dependent
Resistor (LDR) sensors as the inputs of the system. The tracking strategy utilizes a digital logic design of the
sensors’ participation implemented in a projection system to simply rotate around the primary (northsouth)
axis and the secondary (east-west) axis. In the experiment, the proposed tracking system and the fixed
flat-plate system were evaluated for the comparative study. The experimental results show that the proposed
tracking system increased the efficiency of electrical energy by averagely 44.89%, using the proposed system

The proposed solar tracker is derived from a closed loop
control system that is largely based on the field of electrical
and electronics engineering. This system is used to position
solar panels to track the position of the sun throughout the
course of the day so as to achieve higher efficiency of power
generation. The component of the electronic system consists
of a microcontroller, a stepper motor, Light Dependent
Resistors (photo sensors). The components are grouped into
the following units and illustrated in the block diagram below.
? Power supply unit
? Light sensor unit
? Stepper motor driver unit
? Display unit
? Central processing unit
Benefits of the ProjectThe primary and secondary axes work together to allow these trackers to point the solar panels at specific points in the sky. Advantages of dual-axis trackers include: Higher degree of flexibility, allowing for a higher energy output on sunny days. Higher degree of accuracy in directional pointing.
