Abstract

The purpose of this paper is designing and study the
performance of PV tracking system to get maximum power output.
A suggested automatic tracking system to make PV system
oriented always facing perpendicular to the sun along a day time,
since sunrise tell sunset is presented . This tracking system
consists of sensors, comparator circuits to get the direction of
motion and to drive stepper motors until get the equilibrium which
is facing and perpendicular to the sun. Two tracking subsystems
are designed for the proposed automatic closed loop tracking
system. These are one for horizontal equilibrium and the other for
vertical ones.
