Abstract

The aim of this paper is to present a solar energy collection technology by a photovoltaic cell. To present this efficient solar distributed generation system, a dual-axis solar tracker is designed. The tracker actively tracks the sun and changes its position accordingly to maximize the power output. The designed tracking system consists of sensors, microcontroller operated control circuits to drive DC motors and gear- bearing arrangements with supports and mountings. Two geared dc motors are used to move the solar panel so that sun’s beam is able to remain aligned with the solar panel.

Keywords: Solar tracker, LDR, Microcontroller, Geared DC motor, Power gain.

Article published in International Journal of Current Engineering and Technology, Vol.4, No.5 (Oct-2014)
