Abstract: This paper focuses on the sensitivity analysis of N alike evacuated tubular collectors integrated double slope solar distiller unit (NETCDS) using computational program in MATLAB considering a typical day of May of New Delhi climatic situation. The one-at-a-time (OAT) technique has been used for the analysis and it has been concluded that potable water yield is most sensitive with respect to number of collectors followed by water depth and mass flow rate. The average value of sensitivity figure for potable water yield as well as daily exergy output with respect to number of collectors has been found to be 0.68 and 1.4 respectively.

Keywords: sensitivity analysis; evacuated tubular collector; ETC; double slope solar still; exergy.
