Solar distillation is a promising technology for clean water production in areas with abundant solar energy. The main constraint of this technology is low production capacity. In various studies, it has been found that improving water evaporation and vapor condensation inside distillation units can help in increasing the productivity of the solar distillation unit. In the proposed research work single basin double slope solar distillation unit was modified using external reflectors and a solar photovoltaic driven condenser. Experimentation was carried out for comparative performance evaluation of simple conventional distillation unit and modified distillation unit with external reflector and condenser. It was found that the external reflector on the glass cover increases the incident solar energy and thus increases water temperature inside the distillation unit. The rate of evaporation also increased due to condensing fan and condenser coupled with the distillation unit. Results obtained for comparative performance simple distillation unit and modified distillation unit shows that the productivity of single basin double slope solar distillation unit with reflector and SPV drove condenser was 35%. Also, it was found that the modified distillation unit was economically feasible than the conventional distillation unit.
