Abstract

New designs and production methods are used to manufacture cost effective flat solar collectors, using local materials and simple fabrication techniques. This is applied to absorber plate, collector cover, brazing, soldering and adhesive materials, the insulation and the casing as well. The different joints of the absorber are subjected to thermal cycling to determine the fatigue limit and therefore the lifetime of the absorber plate. The developed collectors are tested in a test rig to evaluate their performance and thermal efficiency
