Portable Solar PV based Water Purification System for Subcontinent Conditions

Water scarcity is becoming one of the major problems in India. It endangers the health, economy, environment and food supply of India. Nowadays, the cost of purified water has increased tremendously. To overcome the demand for drinking water, a small-scale solar energy-based water purification system is proposed. The novelty of the proposed work is to supply drinking water continuously without any interruption and minimize the cost of water purification. In this work, a desalination chamber is coupled with the solar panel. During lack of solar energy, the potential energy of the water is utilized for the purification process. The opening and closing of the valves are controlled by the microcontroller based on the sensor outputs. The energy efficiency and water quality of the system is analyzed and compared with the conventional water purification system in a short-term basis.
