A solar-powered humidification–dehumidification desalination (HDD) system is a promising technique for small-scale freshwater production. This paper presents the theoretical investigation of a flat-plate solar water collector (FPSWC)-integrated HDD system located in Kozhikode, India. A zero-dimensional thermo-optical sub-model is employed to simulate the performance of FPSWC after due validation with outdoor experimental data and literature results. This sub-model is subsequently coupled with the main HDD model, which estimates heat and mass transfer, thereby simulating the performance of the FPSWC-HDD system. The influence of various parameters such as feed water-to-air mass flow rate ratio (MR), component effectiveness, collector feed water inlet temperature, and inlet air relative humidity on performance parameters including freshwater yield, gain output ratio (GOR), and recovery ratio (RR) is investigated. Results showed that freshwater yield is optimum at MR of 2, and the maximum freshwater yield can reach about 6.822 kg day −1 in March at MR of 2. The effectiveness of the dehumidifier has a more significant effect on freshwater yield, GOR, and RR than that of the humidifier. Collector feed water inlet temperature and inlet air relative humidity also influence the system performance. The estimated cost of freshwater production is about 0.075 $ L −1 .
