Abstract

The aim of this research is to track photovoltaic panel following sun orientation in order to obtain maximum output of the panel. This research has been conducted in mechanical and electrical laboratory. The tracking system has used dc motor that utilizes AT Mega 8535 microcontroller to control the movement of the tracking system. The movement is 15o every hour, from east to west (8 pm – 4 am). Keywords: photovoltaic, single axis, tracking system.

Abstract

This study aims to determine the effect of the use of a vortex generator on the pressure distribution of the NACA 23012 airfoil. The research method is experimental testing of the NACA 23012 airfoil model with the addition of a vortex generator in the wind tunnel with variations in air velocity 20.96 m/s2, 28.48 m/s2, and 33.90 m/s2, as well as with the angle of attack. The results showed that the airfoil with a vortex generator had a lower pressure coefficient (Cp) than without using a vortex generator.
