MODULAR SOLAR FIELD

摘要

A solar thermal energy system (20) includes a plurality of modules (22), which are connected end-to-end to define an extended solar trough. Each module includes a frame, having an outer edge of circular profile and an inner edge of parabolic profile, having a focus at a geometrical center of the circular profile. The frame includes first and second end segments (42) at respective first and second ends of the module, and a pair of rigid torque tubes (44) connected longitudinally between the first and second end segments. A motorized drive (46) engages and rotates the outer edge of the frame about the geometrical center. Multiple mirror segments (40) are fitted to the inner edge of the frame. At least one heat transfer tube segment (24) is held stationary at the geometrical center of the frame.
