Abstract:
Solar trackers are machines that track position of the sun, and can increase the receiving ability of solar panels.
The incident irradiations of the sun on the panel vary with respect to time, to maximise the receiving power it is worthwhile to
implement a tracking mechanism. In current work, the focused surface orientation is based on dual axis tracking using hybrid
technology. For effective tracking, solar panel is bring into line where light intensity is more and the sun rays are perpendicular
to the panels by using appropriate sensors and assures command from designed controllers to the two positioning motors.
During initial conditions and rainy seasons, another chronological technique which is also combined and implemented. For
this technique, a solar tracker is designed and implemented based on Sun earth relations, which could predict the precise the
actual position of the sun, by latitude location, thereby avoiding the need to use sensors. The proposed technique reduces the
cost of the tracking method and makes it cost-effective. This paper proposed a dual-axis solar tracker to improve the absorption
and production of sun based power conversion and to lessen the system cost with the thought of simple assembling and
collecting.
