One of the popular devices that harness the solar energy is solar hot water system (SHWS). A solar water heater consists of a collector to collect solar energy and an insulated storage tank to store hot water. The solar energy incident on the absorber panel coated with selected coating transfers the hat to the riser pipes underneath the absorber panel. The water passing through the risers get heated up and is delivered the storage tank. The re-circulation of the same water through absorber panel in the collector raises the temperature to 80 C (Maximum) in a good sunny day. The total system with solar collector, storage tank and pipelines is called solar hot water system.
• Energy independence
• No recurring cost, free hot water supply 24*7.
• Negligible maintenance
• Minimal initial investment
• Lucrative government subsidy options.
• No calcium deposits in pipelines hence efficient and long lasting system.
