The techno‐economic analysis of a solar distillation system incorporating the effect of subsidy, rainfall water, salvage value and maintenance costs of the system is presented. The analysis is carried out by two methods, namely the marginal efficiency of capital and the average cost per year. The rate of inflation in maintenance costs is also incorporated. It is observed that the cost per kWh for producing distilled water as calculated by the average cost per year method is lower than that calculated using the marginal efficiency method. Irrespective of earlier research, it is established that the rate of increase in maintenance costs reduces the optimum lifetime of the system, and, for a practical system, the rate of increase in the maintenance costs must exceed the inflation rate and cannot be taken as constant.
