Abstract

The mode of operation of mini parabolic solar panels made of germanium, mild steel, and aluminum are investigated experimentally, as a means of providing heated water on farmland; the process is also modeled. Angular adjustments of the solar collectors from 70-90^o are adopted in order to determine the best material of construction for the parabolic solar collector and the angular orientation with the highest heat collection tendency and absorption rate. The highest quantity of adsorbed heat/best heating effect of the solar collector is obtained at an angular orientation of 80^o for mild steel and aluminum. It is also observed that the parabolic solar collectors have optimum exposure time, after which the heating rate drops, or there is loss of heat from its surface. The experimental and model estimates, in terms of heat absorption for the mild steel solar collector at 70 and 90^o angular tilts, shows that the optimum heating time is 40 min while at 80^o, it is found to be 50 min.
