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 16,430 L. The cost per liter of water produced varies from $0.032 to $0.038, depends on the location.
