A Solar Water Heater (SWH) is a device that uses solar energy to heat water. Solar Water Heater have several advantages over conventional water heating systems. For consumers, they save electrical energy, save interior space (because they are usually located on rooftops) and eliminate the risk of accidents in bathrooms due to electrical water heating equipment, They require little or no care and attention while providing hot water for about 300 days in a year in most parts of India. For society at large, they reduce the need for fossil fuels for electrical generation and for fuels such as firewood, coal, furnace oil, etc. that are used in domestic, commercial and industrial boilers. Thereby, they also reduce degradation of the environment.
