The Design and Implementation of a Solar
Tracking Generating Power System
(Inspired by nature: Model Sunflower)
ABSTRACT
Solar energy systems have emerged as a viable source
of renewable energy over the past two or three decades, and are now widely used
for a variety of industrial and domestic applications. Such systems are based
on a solar collector, designed to collect the sun’s energy and to convert it
into either electrical power or thermal energy. In general, the power developed
in such applications depends fundamentally upon the amount of solar energy
captured by the collector, and thus the problem of developing tracking schemes
capable of following the trajectory of the sun throughout the course of the day
on a year-round basis has received significant coverage in this project. In Aden city (Yemen ),
the improvement in the performance of a solar cooker during summer was found to
be as much as 40% for higher elevation angle and 70% for lower elevation angle,
based on the developed tracking algorithms. Moreover, it was shown that the
amount of solar energy captured by a tilted collector could be increased by
more than 40% by adjusting the tilt angle on a seasonal basis.
This project is designed
with AT89S52 MCU. Two LDRs are used to
monitor the solar light condition. These LDR output is interfaced to
Microcontroller through transistor. The controller continuously checks the
voltage level of the LDRs and operates the motor to to face the panel to
maximum level of intensity. The day / night condition is also monitored by
these two LDRs to disable the tracking in night condition. The motor is driven
by H bridge.
This project
uses regulated 12V, 500mA power supply. 7805 three terminal voltage regulator
is used for voltage regulation. Bridge type full wave rectifier is used to
rectify the ac out put of secondary of 230/12V step down transformer.
