Abstract

In this study, a Smart (Light Dependent Resistor,
LDR) Automatic Solar Tracker is intended and successfully
developed. It was developed with unique design criteria such
that it instantly aligns the solar panels position perpendicular
the position of the sun, resulting in a 42% increase in efficiency
of the generated energy when compared to a fixed axis solar
panel. A low-cost solar tracker set-up is uniquely set up to act as
the solar radiation sensor/detector which is used to rotate the
solar panels via the electric motors to position the panels at a
specific angle determined by the light dependent resistor of the
tracker system. A microcontroller Arduino Uno is used as the
microcontroller unit, and the Analogue Digital Converter ports
are used to interconnect the sensor units. To connect the solar
arrays, the Direct Current motor driver ULN 293D is used to
rotate the solar panel at the highest solar power angle. The
digital model was conceptualized on Autodesk® Fusion™ 360,
using four Light Dependent Resistors. The performance
analysis for the simulated model and developed system shows
that the maximum current drawn by the solar tracking sensor
is less than 0.72 mA. “Arduino UNO”, Proteus 7.6 ISIS” and
“Code Vision AVR” are used to write the program code and to
transmit it to the Arduino Uno microcontroller for parameter
estimation.
