Computation of glint, glare, and solar irradiance distribution
| DWPI Title: Solar power system has computing device that comprises computer-executable instructions that generate values that are indicative of solar irradiance at positions corresponding to first pixels |
| Abstract: Described herein are technologies pertaining to computing the solar irradiance distribution on a surface of a receiver in a concentrating solar power system or glint/glare emitted from a reflective entity. At least one camera captures images of the Sun and the entity of interest, wherein the images have pluralities of pixels having respective pluralities of intensity values. Based upon the intensity values of the pixels in the respective images, the solar irradiance distribution on the surface of the entity or glint/glare corresponding to the entity is computed. |
| Use: Solar power system. |
| Advantage: The solar irradiance distribution is computed across the surface of the entity or the glint and/or glares emitted from the entity based upon the values of pixels of the electronic images of the Sun and the entity captured by the mobile computing device. The image of the heliostat or facet beam on the receiver can be captured, where the entirety of the beam is visible in the image. The automated image processing functions can be utilized to recognize the boundaries of the Sun in the electronic image of the Sun and can automatically determine a radius of the Sun in pixels. |
| Novelty: The system (100) has multiple heliostats that are positioned to concentrate solar radiation onto a solar radiation receiver. A portable computing device (110) receives a first electronic image of the receiver. A second electronic image of a Sun (106) comprises a second multiple pixels. The computing device comprises computer-executable instructions that generate values that are indicative of solar irradiance at positions corresponding to the first pixels when executed by a processor of the computing device based upon values. |
