Solar energy collection system

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. Each collector includes a reflector, one or more solar receivers and a support structure. There is a space between the support structures of adjacent collectors in the collector row, where the reflectors of the adjacent collectors extend beyond the underlying support structures 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 support structures of the adjacent collectors. Some embodiments relate to various types of coupling devices and collector arrangements.

AI Technical Summary

Benefits of technology

[0006]In some implementations, the gap between adjacent reflectors is minimal e.g., less than approximately 10 or 15 millimeters. A minimal gap helps the adjacent reflectors cooperate to form a substantially continuous flux line on the receivers of the associated collectors. In some designs, the gap is covered at least in part by a reflective splice that helps further reduce or eliminate discontinuity in the flux line.

Problems solved by technology

Typically, the most expensive component of a photovoltaic (PV) solar collection system is the photovoltaic cell.

One of the design challenges for any CPV system is the need to balance multiple priorities.

Another consideration is the cost of manufacturing, installing and repairing the CPV system.
