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 ...

Low-cost movable heliostat [PDF]

AIP Conference Proceedings, 2022
Movable heliostats avoid the rail systems of rotating heliostat fields. They can be realized cost effectively by modifying low-cost carousel type heliostats. The cost for the modifications is estimated and compared to the savings resulting from the higher efficiency.

A universal heliostat control system [PDF]

AIP Conference Proceedings, 2017
This paper describes the development of a universal heliostat control system as part of the AutoR project [1]. The system can control multiple receivers and heliostat types in a single application. The system offers support for multiple operators on different machines and is designed to be as adaptive as possible.

Development of the ASTRI heliostat [PDF]

AIP Conference Proceedings, 2016
The Australian Solar Thermal Research Initiative (ASTRI) aims to develop a high optical quality heliostat with target cost – manufactured, installed and operational – of 90 AUD/m2. Three different heliostat design concepts are described, each with features identified during a prior scoping study as having the potential to contribute to cost reduction ...

Deep Learning Method for Heliostat Instance Segmentation [PDF]

SolarPACES Conference Proceedings
Heliostat instance segmentation (HST-IS) is a crucial component of the heliostat tracking system at Heliogen’s Lancaster test facility. The system estimates the mirror normal of each heliostat by performing a nonlinear optimization-based fitting ...

SolarPACES Guideline for Heliostat Performance Testing [PDF]

, 2023
This guideline focuses on Concentrating Solar Technologies (CST). Power tower or central receiver systems use 2-axis tracking mirrors, so called heliostats, which reflect and focus the sunlight onto a receiver on top of a tower during the day for heat ...
