The image processing algorithm uses photogrammetry to calculate the camera position for each image frame, and the accuracy of the estimated optical errors is highly sensitive to the calculated...

...Bernhard W. Adams Concentrating solar power (CSP) facilities need to ensure alignment of all sun-tracking heliostats onto the sunlight receiver. A method is proposed to keep all heliostats in a CSP facility under closed-loop pointing control while also providing feedback on the detailed alignment...

...Daniel Tsvankin; Matthew Muller Structures manufactured from steel comprise up to 40% of a concentrating solar thermal power (CSP) heliostat's cost. Composite structures represent a potential opportunity to reduce this cost. A reference heliostat structural model has been created with a reflector...

Krauth; Christoph Happich; Niels Algner; Rafal Broda; Andreas Kämpgen; Alexander Schnerring; Steffen Ulmer; Marc Röger The pointing calibration of a newly built heliostat field can take up to several years. The state-of-the-art method typically used is accurate but slow. A faster method...

...Chad Augustine; Alexander Zolan; Kenneth Armijo The Heliostat Consortium (HelioCon) was launched in 2021 to advance heliostat technology. One of its first efforts was to do a detailed analysis of gaps in technology and capabilities in the heliostat industry and complete a roadmap study describing...

...) tracking method is developed to evaluate tracking angles. Instead of a target, a heliostat is pointed toward the on-field center point of the tower. Therefore, a spinning-axis of rotation is a line joining a heliostat, and a center of the tower and elevation-axis is perpendicular to it. This aiming...

...Erminia Leonardi; Lorenzo Pisani The design of a solar field is one of the crucial aspects when a solar tower system is realized. In general, shading and blocking effects, which are the main causes of solar power losses, are minimized displacing the heliostats each other quite distant, with typical...

... 2013 04 08 2013 A new method for the heliostat field optimization is presented. The method is intended for further performance improvement after initial layout with a standard heliostat field layout tool. During the field refinement, the heliostats are repositioned around their original...

...L. Amsbeck; R. Buck; A. Pfahl; R. Uhlig In standard heliostat design, the usual strategy of cost reduction is to increase the mirror area of the heliostats. This not only leads to a reduction of specific drive cost but also to an increase of the torques caused by the wind loads, resulting in higher...
