Abstract


Here authors report in, a brief introduction about solar collectors and their efficiency. An overview of types of solar collector with respect to concentrated and non-concentrated solar collectors, In this research we have covered recent applications based on solar technology like; water heater, cookers, dryers, solar ponds, air-conditioning, chimneys and power plants. Recent resurgence towards flat-plat solar collectors has shown that their efficiency can be increased by controlling certain parameters such as different fluids from which are made of. These fluids included water, 0.2 wt% Al2O3, 0.4 wt% Al2O3, 0.4 wt% Al2O3 with surfactant, 0.2 wt% MWCNT, 0.4 wt% MWCNT, and 0.4 wt% MWCNT with surfactant and finally effect of pH (3.5, 6.5, and 9.5) was also highlighted. The best fluid was found to be used MWCNT.
