FFIAM (Full-Field Irradiance Analysis Model) evaluates the reflected-sunlight irradiance in the airspace of a concentrating solar power (CSP) field during standby. It assesses the entire field volume rather than the receiver alone, resolving where high-irradiance regions form, how intense they are, and how they shift as the sun position and the heliostat aim strategy change.
