Solar flat plate collector enhanced by two reflectors: optimum tilts of reflectors

Introduction. In some solar concentrating system applications, in which the incoming sunlight is augmented by using commercial flat plate reflectors placed on different sides of planar collector, it very important to choose optimum tilts boosters (attached edge-to-edge top and bottom collector) for each month, enhance their received irradiation over year southern Algeria. The novelty proposed work consists development a novel mathematical model reference reflector’s tilt angles collector plane, optimal are optimized average day month. Purpose. This paper proposes analytical two identical planer reflectors, latitude tilted optimizing inclination during daytime throughout Ouargla city, southeast Methods. Optimal were obtained searching captured collector’s surface from reflector representative month year. After that, used calculating area comparing them without reflectors. Results. findings this showed that variable one another upper reached its maximum June minimum December, contrarily lower reflector. Again, an increase 28.05 % daily with compared conventional one.
