Review of Recent Resurgence Towards Solar Collectors and Solar Collectors efficiency

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 flatplat 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. Keywords
