Figure 3.
The line graph illustrates the percentage change in performance ratio, ? P R, plotted against hour of day in U T C. Three curves represent Amibil, Ariza, and Zebro. During most daytime hours, ? P R values for all three locations fluctuate close to zero, indicating relatively small changes. Amibil shows minor positive and negative variations through the day, followed by a sharp increase in the late afternoon. Ariza exhibits modest positive values in the early morning, small negative deviations around midday, and a noticeable rise toward the end of the day. Zebro displays larger negative deviations in the early morning, gradual recovery to positive values around midday, and a pronounced increase in the late afternoon. The graph highlights contrasting temporal patterns in performance changes among the three locations.Differences between typical meteorological year and ERA5-Land baselines for each photovoltaic plant
