A new heliostat modeled on South African data is using a pentagonal reflector design, innovative construction techniques and smart software to boost the cost efficiency of tower plants.
Heliostat fields typically contribute about 50% of the capital investment for CSP tower plants, according to a study by SBP Sonne, the German engineering firm which has developed the Stellio heliostat design.
