Due to the irregular availability of solar energy, the increment in the effective working period of the distillation process is a big challenge. Since nanofluids are highly efficient heat transfer carriers for harvesting solar energy to be used in the solar distillation process. Therefore, the present research work has been carried out to analyze the productivity of single slope solar still using two different nanofluids of Al2O3 and CuO along with base fluid (water). In this experiment, the comparison of the performance of solar stills at 2cm water depth without and with Al2O3 nanofluid, as well as CuO nanofluid of 0.2% concentration in a floating cylinder of silver (Ag), has been done. The results show that the nanofluids enhance the evaporation rate and the distillate output as 505ml and 650ml using Al2O3 and CuO nanofluid, respectively while without nanofluid, the output was 265 ml. It has also been found that solar still with CuO nanofluid in Ag cylinder has greater solar still efficiency than solar still with Al2O3 nanofluid and without any nanofluid.
