PREDICTING THE BACK SURFACE TEMPERATURE OF PHOTOVOLTAIC MODULES IN HOT AND HUMID CLIMATES
Keywords:
Photovoltaic, thermal modelling, back surface, hot and humid climateAbstract
In this study, the temperature of the back surface of a photovoltaic (PV) module was calculated based on thermal energy balance. A 1D analysis was also conducted. Each layer was modeled in consideration of the effect of heat transfer modes, such as conduction, radiation, and convection. The temperature value of each layer is important for estimating of the efficiency the module or other PV applications. The PV thermal (PVT) is an innovative design that utilizes PV, and back surface temperature is applicable in the detailed analysis of each PVT collector layer. A few assumptions were made to simplify the analysis. Experimental and thermal modeling results are satisfactory, and irradiance does not fluctuate suddenly. The correlation coefficient (r) and the percent deviation in root mean square (e) are 0.931 and 12.1%, respectively. When irradiance fluctuates suddenly, r and e are 0.345 and 58.5%, respectively.References
