Method of solar power prediction
Abstract
Techniques for estimating direct and diffuse sunlight reaching a location as a function of time using color whole sky images are provided. In one aspect, a method for forecasting solar insolation is provided that includes the steps of: obtaining color whole sky images using a digital camera which are taken at different times, and wherein an image of a solar disk is present in at least one of the color whole sky images; creating sky transparency images from the color whole sky images; determining atmospheric solar scattering based on a width of the solar disk in the color whole sky images; determining cloud motion trajectories from a time series of the sky transparency images; and calculating the solar insolation as a function of time using the sky transparency, the atmospheric solar scattering, and the cloud motion trajectories. A system for forecasting solar insolation is also provided.
