One of the most significant issues that need addressing is the lack of clean and fresh water. There is no substitute for water, there is a growing need for innovative modern desalination systems and the design of modern solar-driven desalination. A normal solar desalination system consists of a tank, a glass plate to cover the tank and, a small reservoir to collect it. We will incorporate additional setups into our solar desalination system to improve the performance of the standard traditional solar desalination system. We will primarily adjust the shape of the tank to an inverted trapezoidal so that much of the time the sunlight appears directly and we will add a fin set up to maximize the surface area as the surface area is directly We would also black coat the inside of the tank in proportion to the heat transfer so that it retains more heat than normal. With the aid of a heat exchanger setup, we can initially preheat the saline water so that the process proceeds at a much quicker pace. the overall efficiency of the desalination plant is increased by 20%.
