ABSTRACT:
This portion of the comparison study identifies the major mechanical design and cost differences between concentrator subsystems. Parabolic dishes and troughs are designed to the same specifications as heliostats, using the same glass mirror/steel structure design concept and their costs

are estimated on a consistent, comparable basis, using the heliostat cost data base. The results show inherent cost differences arising from differences in geometry, the cost of providing curvature and wind loadings. The estimated cost increases, relative to heliostats, are 15% to 50% for dishes and 0% to 30% for troughs, considering the combined effect of several analysis uncertainties. The concentrator cost estimates are used in the systems analysis volume (Volume V) to obtain cost/performance estimates for the overall systems. Show Less
