Title:
OPERATING A HELIOSTAT AND PHOTOVOLTAIC PANEL TOGETHER
Document Type and Number:
WIPO Patent Application WO/2014/016727
Kind Code:
A3
Abstract:
Shading by clouds can affect the amount of flux on a heliostat which in turn can affect the energy generated by the solar device. Real-time monitoring of clouds shading is necessary for efficient operation of the entire solar power system. The output of a photo-sensitive panel attached to a heliostat may be measured in direct unhindered sunlight and at a first orientation. The output of the photo-sensitive panel may then be predicted for a second orientation. Upon measuring the actual output of the photo-sensitive panel at the second orientation, a communication function may be performed when output measured at the second orientation of the panel is below or above the predicted output. A reduced-insolation event is indicated by lower-than-predicted output at the second orientation. Upon indication of a reduced-insolation event, the heliostats may be controlled, i.e., the aiming directions for one or more of the heliostats may be changed.
