In a Linear Fresnel Reflector (LFR) solar concentrating system [1] a series of single axis linear
reflectors target the sunrays to a longitudinal facedown receiver on top of a fixed structure. The
LFR technology offers simplicity and reduced costs when compared with the standard Parabolic
Trough technology, but it also suffers from reduced optical performance, especially with large
incidence angles. The present preliminary study explores the possibilities of a variable curvature
geometrical concept for a LFR that would achieve a more focused solar print over the receptor
than in a traditional fixed geometry system.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech
