Unlike conventional electrical power generation (such as fossil or nuclear energy), solar energy is intermittent. The output of a solar power plant is driven by weather and by the cycle of days and seasons. It varies from zero to full power outside the control of plant operators. Spatial and Temporal Variability of Solar Energy summarizes and analyzes recent research by the authors and others to understand, characterize, and model solar resource variability. This research shows that understanding solar energy variability requires a definition of the temporal and spatial context for which...
