Solar Water Heater
Solar Water Heating Systems
Introduction
Solar water heater consists of a collector to collect solar energy and an insulated storage tank to store water. The solar energy incident on the absorber panel coated with selected coating transfers the heat to the riser pipes underneath the absorber panel. The water passing through the risers get heated up and are delivered to the storage tank.
The recirculation of the same water through absorber panel in the collector raises the temperature upto 68ºc + 5 ºc on a good sunny day. The total system with solar collector, storage tank and pipelines is called solar hot water system.
Based on the collector system, solar water heaters can be of two types:
Solar water heater is being used for heating water in homes, factories and other commercial and institutional establishments. It has life of 15-20 years.
By use of solar water heater of 100 litres capacity results in annual savings of app. 1250 units of electricity.
At present there is no any subsidy is admissible on Solar Water Heating Systems. UPCL provides rebate of Rs. 100/- per month for 100 LPD Solar Water Heating System on electricity bills to consumers.
Below mentioned bar graph shows the yearwise installation of solar water heater and cumulative installation of solar water heater till date from FY 2010-11 onwards.
