Abstract
In one aspect of the present invention, a solar energy collection system that includes multiple longitudinally adjacent collectors is described. The collectors are coupled end to end to form a collector row. The collector row extends along a longitudinal axis and is arranged to rotate about a pivot axis to track the sun in at least one dimension. Each collector includes a reflector, one or more solar receivers and a support structure. The support structure includes a tube assembly that underlies the reflector. The tube assemblies of the collector row are arranged end to end along the longitudinal axis. There is a space between the tube assemblies of adjacent collectors in the collector row, where the reflectors of the adjacent collectors extend beyond the underlying tube assemblies to form a substantially continuous reflective surface over the space. A coupling device is positioned in the space between the tube assemblies. The coupling device connects and helps to rotate the tube assemblies of the adjacent collectors. Some embodiments relate to various types of coupling devices and collector arrangements.
