Abstract

The main objective of this study was to measure and determine the efficiency of poly-crystalline, mono-crystalline and amorphous silicon solar module by applying single-axis time/date solar tracker to the installation of photovoltaic panel (dynamic system) as a strategy to increase the performance of the modules under hot-humid climate of Malaysia. The dynamic system in this experiment was designed to support the three types of PV panels which allowed it to move with single degree of freedom (horizontally) according to the sun’s orientation (sunrise to sunset) from east to west. Studies on sun movement in equator countries have been conducted to locate the sun‘s position on site (azimuth and altitude angle) using the Stereographic Diagram and Tabulate Daily Solar Data. It was found that poly-crystalline solar module have shown better performance ratio and average module efficiency compare to the others tested PV module under Malaysian climate.
