Solar Water Heating System for Residential Applications

Solar energy has been used most widely for water heating in many countries. Solar thermal technologies hold significant promise for India, for fairly good solar insulation of 4 – 6.5 kWh/ sq.m /day with an average of 280 cleardays, as well as relative maturity of technology. Yet, against an estimated potential of 140 million sq. km. of collector area, India has installed only a little over 1.5 million sq. km. of collector area till date.

However, the Ministry of New and Renewable Energy (MNRE) understands the importance of solar water heating systems for various applications, and significant efforts have been made towards the development and dissemination of the same.
