Abstract

Power measurement for photovoltaic(PV) modules is a key factor in evaluating the performance, safety, and long-term reliability of photovoltaic modules. The power measurement for the PV module is made by measuring the electrical characteristics by a solar simulator, which is an artificial solar light source. These solar simulators are divided into two types, which are the pulse-type simulator and the continuous type simulator. In the pulse simulator, the temperature characteristics are stabilized and there is not temperature difference between the inside and outside of the solar module to be measured. The continuous irradiation simulator has fluctuations in temperature characteristics due to continuous light irradiation, and there is a temperature difference between the inside and outside of the PV module to be measured. The variability of these temperature characteristics can be improved through temperature correction. In addition, the convenience of measurement can be improved by predicting the power and correcting the irradiance to the temperature correction. The integrated correction of temperature and irradiance proposed in this paper can be contributed to the power measurement of PV modules in the continuous type simulator.
