Abstract
AbstractThe irradiance from the sun or solar spectral irradiance can have significant variance in different locations due to the latitude, humidity, and cosine effect of incident sunlight. The performance of the outdoor photovoltaic (PV) modules is greatly influenced by the solar spectrum. In this study, the effects of the local spectral irradiance on outdoor PV modules are of interest. With similar irradiance and operating temperature, the performances of the PV modules at different locations differ as compared with that of the benchmark AM1.5G results. In order to predict the actual PV module performance under local climate conditions, two locations in Peninsular Malaysia are considered. Twelve types of solar PV modules from different manufacturers and materials are analysed. Two sets of experiments were conducted using variants of Genetic Algorithms, where the Power Conversion Efficiency (PCE) at different irradiance levels is first considered. Results from the study show that there is a gap between the AM1.5G results and the outdoor results from the locations being analysed.KeywordsGenetic algorithmOptimizationPhotovoltaic modulePower conversion efficiency
