Photovoltaic System for a Board of The Faculty Map in a Thai University

Abstract

This paper presents the design of a stand-alone Photovoltaic (PV) system to supply an electric power for a board of the faculty map. This system has been installed at the Faculty of Engineering in Rajamangala University of Technology Thanyaburi (former name was Rajamangala Institute of Technology-RIT), Klong 6, Thanyaburi district, Pathumthani province of Thailand. The purpose of this work is to study and analysis of the performance of the PV system that to be installed at the Rajamangala University of Technology Thanyaburi (RMUTT). The design of control circuit was experimentally done in this work. Protection of the battery from damage from deep discharge and overcharge by a controller was also considered. In addition, microcontroller program for controlling the operation of LED (light emitting diode) lamps was developed to show the way from starting place to another department or another building that someone who wants to go within the Faculty of Engineering. Users are able to know the amount of space in meters between the starting place and destination from reading on display segment. During the night time, an operation period of time for the fluorescent lamp between 19.00-22.00 hours was controlled. The system performance of the system including the life cycle cost analysis of the system and measuring data of solar energy at the design location are addressed.
