PV module power is calculated on PV module surface temperature adjustment by irradiation on the summer and autumn in NOCT(Nominal Operating Cell Temperature) conditions. The summer and autumn periods were selected because of large variation in outdoor air temperature and irradiation. This study was performed to understand relationship between PV module surface temperature and photovoltaic power using field measurement. As a results, it was determined that the amount of irradiation was proportional to the amount of photovoltaic power in the field measurement. However, it was also identified that the PV power generation decreased by increased PV module surface temperatures due to irradiation.
