A novel PV/T-distillation system has been introduced in this paper. The main parts of the proposed system are a single slope basin solar still with PV/T cell immersed at the bottom of its basin and coupled with outside finned condenser. A steady-state mathematical model has been developed to study the performance of the system. The simulation results show a good agreement with those obtained by some theoretical and experimental published studies for systems similar, in general, for our proposed system. Also, in this paper, the effects of solar radiation, wind speed, ambient temperature and condensing chamber on the performance of the system have been discussed. (C) 2016 Elsevier Ltd.
