Optimal position of flat plate reflectors of solar thermal collector

Theoretical and experimental investigation of the thermal performance of a double exposure flat-plate solar collector

“…The possibility of using more flat-plate reflective surfaces was also investigated. Thus, Kostić and Pavlović (2012) proposed the use of two reflectors placed on top and in front of the collector. For this CRS, the optimum yearly tilt angle of both of the reflectors for a fixed collector tilt angle of 45°(43°N latitude) was determined.…”

“…A small part of those investigations has focused on a system of the flat-plate solar collector and flat-plate reflector (McDaniels et al, 1975;Larson, , 1980Hussein et al, 1999;Taha and Eldighidy, 1980;Tanaka, 2011Tanaka, , 2015Ekechukwu and Ugwuoke, 2003;Farooqui, 2015;Grassie and Sheridan, 1977;Bollentin and Wilk, 1995; http://dx.doi.org/10.1016/j.solener.2015.06.038 0038-092X/Ó 2015 Elsevier Ltd.

Thus, McDaniels et al (1975) and determined the optimal tilts of a fixed reflector and collector during the winter period for a collector-reflector system (CRS) in which the reflector was placed in front of the collector.…”

Performance Evaluation of Photovoltaic Solar System with Different Cooling Methods and a Bi-Reflector PV System (BRPVS): An Experimental Study and Comparative Analysis

“…The impact of the air cooling mechanism was analyzed under different levels of solar radiation and surrounding temperature. Using a brushless DC fan to reduce the PV panel temperature, the power output was observed with increasing solar radiation [7].…”

Concentrated photovoltaic thermal (CPVT) solar collector systems: Part I – Fundamentals, design considerations and current technologies

“…The booster reflector could be of a flat, triangular, semi-circular, cylindrical, involute, corrugated, or CPC design. Numerous variations with respect to the geometry, location, inclination, area, and spacing of the booster reflectors coupled to a FPC [200,[207][208][209][210][211][212] or an ETC [202][203][204][205][206] are available in the literature. CPCs are another EH-CST variation.…”
