Developing Deformable Facets for Heliostats: An Increased Solar Concentration for Thermochemical Applications with Central Tower Receivers

SolarPACES Conference Proceedings
In the present article a new design of a deformable facet and a heliostat with several deformable facets is presented. Previous work has been made around designing heliostats with concentrating facets in the facilities of the Plataforma Solar de ...

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.

Heliostat Fatigue Loads

SolarPACES Conference Proceedings
An approach to estimate the wind load spectra for heliostats is proposed. It is based on the wind-induced fatigue cycle counts for buildings given by the Eurocode EN 1991 and considers heliostat specific impact factors.
