Improvement of Photovoltaic Module for Increasing Energy Conversion Efficiency

Abstract:

For increasing energy conversion efficiency of PV module, this study was divided to two experiments. The first experiment was to investigate optimal tilt angle of PV module from 0-35° from horizontal plane in facing south for using in Udon thani Province and neighbouring in Thailand. The second experiment was to decrease PV module temperature and to determine appropriate cooling system by using water and small spray nozzles between front and back PV module. The results found, conversion efficiency was high during 15°-25° from horizontal plane for tilt angle in facing south, especially at 25° in whole year. Using thin film by spray nozzles at the front side was higher open circuit voltage and energy conversion efficiency than back side, with 6.06% of increasing open circuit voltage and 1.93% of increasing energy conversion efficiency when compared with no cooling system, due to can thoroughly distribute water on surface area and easily install.
