Solar Water Heating Potential


A solar water heater is the most competitive alternative to conventional water heating methods such as electric geysers and fuel-fed boilers.

It makes an attractive and sustainable option, with its global distribution, pollution free nature, virtually inexhaustible supply and near-zero operational cost. Solar water heaters run on a free fuel (i.e. sunshine), thus saving on energy costs that help recover its initial cost in just 2-4 years.

In India, the Ministry has assessed a techno-economic potential of 40 million sq. mtr. of collector area. Out of this, 20 million sq. mtr is targeted to be achieved by 2022. To accelerate the installation of solar water heating systems, a UNDP–GEF supported project is in operation by the Ministry of New and Renewable Energy since 2009.
