Total solar power generation shows strong seasonality, with strong cyclic behavior with a period of about one year. It seems there were more solar power generation in summers and less in winters, which means that warm days are likely to generate more solar power. Total used electricity also shows strong seasonality and cyclic behavior, while the peaks and nadirs are opposite to that of solar power. Total electricity demand shows a stationary process.
This plot shows the trend of solar power and weather indicators over time. One can choose different weather indicators by clicking the "indicators" dropdown list. From the plot, the fluctuation of humidity has the most amplitude and pressure has the least. The time series plots of solar power and all weather indicators show a stationary process.
