The optical design and thermal performance of a solar power tower system using an array of high-temperature pressurized air-based solar receivers is analyzed for Brayton, recuperated, and combined Brayton–Rankine cycles. A 50 MWe power tower system comprising a cluster of 500 solar receiver modules, each attached to a hexagon-shaped secondary concentrator and arranged side-by-side in a honeycomb-type structure following a spherical fly-eye optical configuration, can yield a peak solar-to-electricity efficiency of 37%.
