The Low Temperature Analysis of the Used PV Modules During On-Site Generation in Thailand

A. Saengprajak and S. Pattanasethanon

This study involved the on-site working characteristic of the multicrystalline silicon (mc-Si) and monocrystalline (c-Si) photovoltaic (PV) modules during operates in the hot humid area. The objective of this study was to find out the crucial temperature which is a thermal boundary for the open circuit voltage (Voc) out put from the PV modules. The output voltages from the PV modules, which various with the climate parameters, were evaluated at the Department of Physics, Faculty of Science, Mahasarakham University. During the on-site investigation, the modules temperatures were assigned at 55, 65 and 75°C, respectively. The data was carried out and analyzed for finding out the crucial temperature of PV modules. Present results show that the Voc of both PV modules were dramatically decreased during the modules temperature is higher than 65°C. In addition, using of both c-Si and mc-Si PV modules at 55-65°C results the Voc output of the PV module in 22-25% decrease from the standard value at the standard test conditions. The study concluded that, both PV modules have no significant differences when operates the modules temperature at lower than 65°C. To keep the module temperature during generation in this location lower than 65°C is benefit for the voltage stability and thermal productivity by PV modules.
