Design and construction of solar thermal water desalination (completely off grid) is one of the goals of the project. Optimal use of solar energy and sustainable drinking water supply for agricultural and drinking purposes should be seen in the plan. Innovative and technological aspects of using solar thermal energy are important compared to existing designs. Energy analysis and economic analysis are required for the proposed design. The pilot capacity is 1 to 5 cubic meters per day of fresh water production from seawater or other saline waters.
