Abstract:
In this study, an electromechanical, renewable energy resources of solar; two axes sun-tracking system designed and constructed. A closed loop system employed for control part. A Programmable Integrating Circuit (PIC) used to control the motion of the sun-tracking surface with photovoltaic (PV) panels. The feedback analog signal coming from FV through a variable resistor was controlling scanning sequence. First, scan to the right and left by the secondary motor and second scans in the forward and backward directions by the major motor. Another two potentiometers are used; one for detects the sun availability and the other to measure the batteries fulfillment. The relay switch biased by a power transistor used to control the batteries charging process.
