Abstract

The photovoltaic (PV) panel produces the maximum power as the incident angle of sunlight is 90°. In this paper, two-axis sun-tracking system keeps PV panel perpendicular to sun light by absolute and relative position sensors signal analysis. It is composed of micro-controller, solar illumination sensor, solar position sensors, stepper motors and drivers, two-axis motion mechanism, zero position switches, limit switches and solar system.
