In this study, a hybrid system with the addition of a greenhouse solar still is proposed to improve the efficiency, performance, and productivity of solar still. The energy analysis is performed with the help of a computer program using a set of typical design and operating parameters. The result showed that the hybrid still coupled with a PCC (parabolic cylindrical concentrator) can produce 110 l/m 2 per day. The temperatures of the basin and water of the hybrid still with PCC are 140 and 100 °C, respectively. The causes are the several sources of temperatures are added together in a single system. The obtained values of efficiency, production, and performance are 160%, 100 l/m 2 , and 2, respectively. The results show also that the temperature and production in the month of January are 70 °C and 50 l/m 2 per day, respectively, despite the negative influence of meteorological parameters. The performance of the suggested hybrid still is found to be higher than that of the single still without a concentrator.
