Secondary reflector for Linear Fresnel Reflector system

摘要

A solar collection system having a secondary reflector is provided. The secondary reflector may be located above a field of primary reflectors and below a solar receiver. The secondary reflector may form a portion of an ellipse or macrofocal ellipse and be operable to reflect at least a portion of the solar radiation reflected by the primary reflectors onto the solar receiver. The secondary reflector may be disposed away from the solar receiver and associated tertiary reflectors such that it does not intercept reflected solar radiation from the outer primary reflectors that would otherwise have struck the solar receiver and tertiary reflectors had the secondary reflector not been present.
