• •Optimization of a new HDH system integrated solar evacuated tubes collectors was conducted.•The mathematical models developed for the collector and the HDH system were validated.•A multi-location analysis was then performed for six locations in Saudi Arabia.•Sharurah was found to have the highest annual output and Dhahran the lowest at 19,445 and 16,430L.•The cost per liter of water produced varies from $0.032 to $0.038, depends on the location. A humidification-dehumidification (HDH) desalination system integrated with solar evacuated tubes was optimized. Then, the optimized system was assessed for the operation in different geographical locations, and the rate of freshwater production and cost per liter were determined in each location. The system design proposed in this paper uses a heat pipe design evacuated tube collector, which performs significantly better based on cost. An HDH desalination system with a closed-air/open-water loop, connected to the collector, was evaluated to determine the optimum operating parameters and the system performance during daytime (from 8 am to 3pm), as well as the average day of each month for an entire year. The impact of the effectiveness of the humidifier and the dehumidifier, as well as, the number of collectors, were also studied. The analyses were performed for Dhahran, Jeddah, Riyadh, Sharurah, Qassim, and Tabuk to determine the effects of varying the geographical location. Sharurah has the highest calculated productivity of freshwater and Dhahran has the lowest at 19,445 and 16,430L, respectively. To have a comprehensive study of the system proposed, a cost analysis was also performed to determine the feasibility of the system and the cost of water production. Results show that the price varied from $0.032 to $0.038 per liter for the locations evaluated.
