Terrestrial Laser Scanning for Heliostat Surface Shape Determination and Canting Errors Correction
SolarPACES Conference ProceedingsCanting errors, resulting from misalignments of heliostat facets, pose a significant challenge to solar power plants' efficiency. Traditional methods of alignment are time-consuming and costly.

Design and optimization of a small scale portable solar tower with different configurations
Results in EngineeringThis paper presents the design and modeling of a small and mobile solar concentrator. The concentrator uses a compact heliostat field of 2 m × 5 m in size, allowing it to be towed on public roads in a utility trailer to off-grid rural areas or places ...

SCADA-Based Heliostat Control System with a Fuzzy Logic Controller for the Heliostat Orientation
Applied Sciences, 2019 In central receiver systems, there are local controls that modify the position of the heliostats, where the trend is to increase the intelligence of the local controls in order to give them greater autonomy from the central control.
