Advantages of Solar Water Heating System
Solar Hot Water System turns cold water into hot water with the help of sun’s rays.
Around 60 deg. – 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
Only soft and potable water can be used
Stainless Steel is used for small tanks whereas Mild Steel tanks with anti-corrosion coating inside are used for large tanks
Solar water heaters (SWHs) of 100-300 litres capacity are suited for domestic application. Larger systems can be used in restaurants, guest houses, hotels, hospitals, industries etc.
Fuel Savings :
A 100 litres capacity SWH can replace an electric geyser for residential use and saves 1500 units of electricity annually.
Avoided uitility cost on generation
The use of 1000 SWHs of 100 litres capacity each can contribute to a peak load shaving of 1 MW.
A SWH of 100 litres capacity canprevent emission of 1.5 tonnes of carbon-dioxide per year.
