The 13 sets of maximum power points corresponding to different radiations are shown in Fig. 6. Fig. 6. The P-V curve of photovoltaic modules under different radiation. Fig. 6 shows the data for the output power and voltage of the PV module under 100 W/m 2 - 1300 W/m 2 radiation conditions.
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.
Dahlioui et al. showed that solar radiation greatly affects the output power of PV modules, but airborne pollutant particles reduce their power generation efficiency by 15 %. Yue et al. found that suitable orientation of PV panels is beneficial to increasing the power generation of PV systems.
3.4. Difference in annual power generation of PV modules in winter and summer By processing the solar radiation data (Fig. 10), Solar radiation is divided into 14 levels, and all of the measured solar radiation are classified as 100 - 1,300W/m 2.
This equation predicts the maximum output power of a PV module under different radiation conditions. The power generation efficiency is calculated for different radiations and it shows a trend of increasing and then decreasing with increasing radiation. The power generation efficiency reaches its maximum at a solar radiation of 800 W/m 2.
The solar radiation near the surface is the main reason that affects photovoltaic power generation. Accurate ultra-short-term solar radiation prediction is the premise of photovoltaic power generation prediction. Here the cloud movement prediction method based on the ground-based cloud images is presented.
