A review and classification of layouts and optimization techniques used in design of heliostat fields in solar central receiver systems

Solar Energy, 2021
Central receiver systems are considered one of the most efficient ways to harness solar thermal energy. A significant component of these systems is a heliostat field which accounts for approximately 50% of the capital cost and is responsible for 40% of ...

Heliostat Tailored to Brazil

Proceedings of the ISES Solar World Congress 2015, 2016
For Brazil it is important to realize a high local production share because of high import tax rates. The rim drive concept offers an alternative for expensive heliostat drive solutions with slew and linear drives from abroad. By (locally produced) rims the demands on the drives regarding strength and precision are reduced to a very low value and low ...

HelioPoint – A Fast Airborne Calibration Method for Heliostat Fields

Journal of solar energy engineering
The initial 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 could reduce the commissioning time and therefore increase the viability of
