Generally, when a photovoltaic power generation system is installed in a house, we will investigate how much power generation can be expected. This system is highly dependent on solar radiation intensity, so it is necessary to simulate under the effect of partial shading. In this study, we verified the operation of the output under partial shading conditions and constructed a simulator that reflects the effects of partial shading. In addition, using data from late February to early March, we compared the calculated values in the constructed simulator with the measured values, the error was extremely small and almost exactly calculated. However, there are days when the calculated values without considering partial shading agree with the measured values, and the tendency of this problem to occur will be discussed in the future.
