Photovoltaic charge station on garage roofs with passive reflectors

Abstract

This study involves a photovoltaic charge station which could be placed on garage roofs in order to charge the battery of an electrical car. The aim of this thesis is to design an efficient photo voltaic charge station and construction of omega type solar charge station. That's why various models were designed and calculated amount of energy. A photovoltaic charge station has 16 photovoltaic modules with dimensions 1293 mm*329 mm*34 mm. In this study five different type of solar charge stations were compared. These are, omega type solar charge station ( first type ), south facing type solar charge station with different angles ( second type ), south facing type solar charge station with fixed angles ( third type ), inverse of omega type solar charge station ( fourth type ), optimisation of south facing type solar charge station with different angles ( fifth type ). After calculating of collected solar energy, the fifth type solar charge station was chosen as the most efficient solar charge station. After these theoretical calculations, omega type solar charge station has been installed on the Electrical Engineering Department's roof. Voltages and current intensitiesof omega type solar charge station were measured from 28 June 2000 to 15 October 2000 in order to determine the solar power obtained and to compare it with the calculated values and measured data by Solar Energy Institute of Aegean University and meteorological station in Glizelyah. The results obtained are satisfactory.
