The solar seasonal component reaches a peak in July summer of 1.25. Table 4 calculates the average of the seasonal component in four seasons. Spring has the most abundant wind resources with a maximum value of 1.06, while the richest solar resources are in summer with a maximum value of 1.18. Fig. 7. Analysis of seasonal component.
Thus in principle a factor of 6 to 1.5 difference per solar power collecting footprint between seasons occurs, next to the diurnal day and night fluctuations, and varying cloud covers. These seasonal and diurnal influences multiply with each other to obtain the total solar power.
These events demonstrate seasonal distribution characteristics and can result in renewable inadequacy over different timescales, presenting challenges for power system planners and operators. Currently, lots of studies have focused on analyzing and modeling the seasonal variation of renewables in the power system.
DISCUSSION The solar and wind power generation on large scale grids will vary strongly and systematically on both a daily and seasonal timescale. The comparison with the demand for energy during the day and seasons, results in significant storage demands on different timescales if one intends to completely use the energy that is generated.
One consideration for solar energy systems is the seasonal nature of the availability of light. Changes in the hours of darkness throughout the year and prevailing weather conditions act to limit the light levels in winter compared to summer, at least in locations that are away from the equator.
Impact of seasonality/technical factors on power generation efficiency quantified. Results can contribute to improving new/existing renewable power generation systems.
