Project Profile on Solar Water Heater

Abstract

In these days of power shortages non-conventional and renewable sources of energy are gaining importance. India, with its tropical climate, can tap Solar energy for heating water for domestic & industrial purposes & various non-heating purposes, like street lighting etc.The non-convetional water heating system based on solar energy has a major advantage in that, once the initial installation is carried out, the consumer will have minimum recurring expenditure. This system cnsist of collector panels of 2M X 1M, a cold water tank & insulated piping. If a stainless steel tank is installed, the water thus heated can be stored in those tanks, in 100, 200 & 250 lpds for domestic purposes & 1000, 2000 & 3000 lpds for non-domestic segments like hotels, hostels etc. Relevant specifications are IS:11907:1986-Recommendations for calculations of solar radiation on building, IS:7025:1973-Guidance on solar radiation testing.
