A Study of Linear Fresnel Solar
Collector Reflector Field
for Performance Improvement
Gunjan Kumar and Hemant Gupta
Abstract Linear Fresnel collector (LFC) is the source of useful energy generation
where solar radiations are directed toward a fixed receiver. The operation of the
collector is based on line focus technology. In the solar field, the receiver is placed
centrally above the linear reflectors. It has less capital cost than parabolic trough
collector (PTC) but its optical performance lags behind. However, various efforts are
already taken to enhance the performance but still, it has scope to improve. Many
kinds of solar field designs of this technology are available, and they are installed in
both prototypes and commercial plants until the current time. In this paper, various
LFC solar reflector field designs for performance improvement are reviewed. Effect
of design parameters, like field orientation, location, numbers, size, focal length,
and space between reflectors, is reported. In addition to that, LFC development and
future aspects are also studied. Such reviews are useful for researchers pursuing or
willing to work in this area.
