Solar Water Heater System

Technical Specifications

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.

Salient Features of Solar Water Heating System

Solar Hot Water System turns cold water into hot water with the help of sun rays.
Around 60 deg to 80 deg. C temperature can be attained depending on solar
radiation, weather conditions and solar collector system efficiency
Hot water for homes, hostels, hotels, hospitals, restaurants, dairies, industries etc.
Can be installed on roof-tops, building terrace and open ground where there is no shading, south orientation of collectors and over-head tank above SWH system
SWH system generates hot water on clear sunny days (maximum), partially clouded (moderate) but not in rainy or heavy overcast day
Stainless Steel is used for small tanks whereas Mild Steel tanks with anticorrosion coating inside are used for large tanks
Solar water heaters (SWHs) of 100-300 liters capacity are suited for domestic application.
Larger systems can be used in restaurants, guest houses, hotels, hospitals, industries etc.

Fuel Savings :
A 100 liters capacity SWH can replace an electric geyser for residential use and saves 1500 units of electricity annually.
Avoided utility cost on generation
The use of 1000 SWHs of 100 liters capacity each can contribute to a peak load saving of 1 MW.

Environmental Benefits
A SWH of 100 litres capacity can prevent emission of 1.5 tonnes of carbondioxide per year.

Life :
15-20 years

Approximate cost :
Rs.18000- 20,000 for a 100 liters capacity system and Rs.120-150 per installed litre for higher capacity systems

Payback period :
3-4 years when electricity is replaced
4-5 years when furnace oil is replaced
5-6 years when coal is replace
