A solar thermal collector collects heat by absorbing sunlight. The term "solar collector" commonly refers to a device for solar hot water heating, but may refer to large power generating installations such as solar parabolic troughs and solar towers or non-water heating devices such as solar cookers or solar air heaters. [1]
The present study comprises the solar collector classification, applications and their main parameters with a special focus on opaque solar collectors. 1 Introduction ... Depending on the construction characteristics, solar collectors can be classified in several ways. According to Lai et al. [10] solar air collectors can be grouped into:
Nonimaging collectors with low concentration ratio and linear imaging collectors with intermediate concentration ratios. The chapter deals with general information on optical principles and heat transfer that is important in concentrating collectors, in particular the optical performance and thermal performance of concentrating collectors.
For characterizing the solar field ({A}_{sf}) is the best choice, of course. The optical active aperture should be as large as sensible for a given solar field area, but mutual shading and blocking prohibit a too dense spacing of the collector lines or the individual heliostats or dish collectors.
