Through the combination of indoor and outdoor solar radiation and photovoltaic power generation system test, the method is applied and validated. The following conclusions are drawn from this research.
How does solar radiation affect the output power of PV modules?
The P-V curve fluctuates more at solar radiation of 800–1300 W/m 2 compared to 100–700 W/m 2, which indicates that the higher the solar radiation, the greater its effect on the electrical power. To predict the maximum output power of PV modules under different radiation, the output power and voltage are firstly dimensionless by Eq.
Does solar radiation affect power generation efficiency?
