Solar Resource Characterization
Researchers: Richard Perez
The initial activities in this field consisted of developing and validating solar radiation algorithms capable of generating the
solar resource parameters needed by engineers for specific applications from quantities that are more commonly available. For instance,
one of these models converts measured global and direct irradiance into irradiance received by plane surface of arbitrary tilt and
orientation such as a roof. Another model reproduces the distribution of daylight luminance in the sky as a function of measured global
and direct irradiance.
Archiving of satellite-derived solar radiation data
Enhancement and validation of models converting satellite images into irradiances
Application of satellite-derived irradiance to the modeling of solar systems
Our ongoing projects in solar resource characterization are sponsored by the National Renewable Energy laboratory, the USDOE and the University of Oregon. These projects include the validation and improvement of satellite-to-direct irradiance models for the detection of solar microclimates in the southwestern US - this will be used for the optimum deployment of solar thermal power plants -- and the mapping of solar radiation components in the Pacific Northwest states.
