Abstract:
Solar Energy is the most essential and prerequisite resource of
sustainable energy due to its abundance and sustainability. One of the ways
to convert this energy into electricity is Photovoltage cells PV. The main
factor in this conversion is the angle of sunlight that faces the PV cells and
due to the movement of the sun; the output of the system varies through the
day and the solution will be tracking the sun through the day. The Solar
tracking mobility platform plays a crucial role in the development of solar
energy applications in order to maintain high levels of power output. In this
project an automated solar tracker has been designed to keep the PV panels
perpendicular to the incoming sunlight through the day according to the user
choice (Dual-Axis, One-Axis, Annual). The system was simulated using
Proteus program, the PV panel was fabricated as a way to measure the solar
radiation, (the photovoltaic panel output power, voltage and current). The
surrounding temperature was also measured to find the effect of the local
environment temperature on the PV performance and efficiency.In order to
achieve the tracking fourlight dependent resistors LDR was implemented to
determine the sun position and using Atmega32 microprocessor to drive two
stepper motors as the movement object. A simple GUI windows was
designed using Matlab to visualize the measured and to control the operation
in the proteus as well as making the user experiment easier and joyful.
