Variation of Heliostat Wind Loads in a Radial Field Array Model

SolarPACES Conference Proceedings
The design of heliostats throughout a concentrated solar power (CSP) plant are currently of uniform design, however, research into the variation in heliostat wind loading within a radially staggered field array can provide insight into potential material

Variation in Reflected Beam Shape and Pointing Accuracy Over Time and Heliostat Field Position

SolarPACES Conference Proceedings
Heliostats are typically constructed with fixed mirror shapes, which they move to varying angles to reflect sunlight onto a receiver.  While heliostat facet curvatures and canting angles are selected to maximize a chosen performance criterion, these ...

More Efficient Heliostat Fields for Solar Tower Plants: The HELIOSUN Project

SolarPACES Conference Proceedings
Heliostats could represent up to 60% of the investment cost for solar tower plants with more than 100 MWe of power, then reducing the cost of heliostats would have an important cost reduction of the plant.
