Solar Water Heating System

Solar Water Heating System

A solar water heating system is a device that helps heat water using the SUN’s energy. This energy is free. Solar energy (sun rays) is used for heating water. Water is easily heated to a temperature of 60-80o C. Solar water heater of Solar water heaters (SWHs) of 100-300 liters capacity are suited for domestic use. Larger systems can be used in restaurants, canteens, guest houses, hotels, hospitals, etc. A 100 liters capacity SWH can replace an electric geyser for residential use and may save approximately 1500 units of electricity annually. Using 1000 SWHs of 100 liters capacity can each result in a peak load reduction of approximately 1 MW. An SWH of 100 liters capacity can prevent the emission of 1.5 tons of carbon dioxide per year.

Key Features

Solar water heaters use the sun’s rays to convert cold water into hot water, as their name implies.

  • Depending on solar radiation, weather, and the effectiveness of the solar collector system, temperatures between 60 degrees and 80 degrees Celsius can be reached.
  • Hot water for homes, hotels, hospitals, businesses, and other establishments.
  • It May be erected without shade, such as on rooftops, building terraces, and open land.
  • Solar water heater systems produce hot water on sunny, clear, and partly cloudy days but not on cloudy or rainy days.
  • Only soft potable water can be utilized.
  • Little tanks are made of stainless steel, whereas large tanks are made of mild steel tanks with an internal anti-corrosion coating.
  • Solar water heaters with 100 to 300 liters capacity are appropriate for home use.
  • Larger systems can be employed in factories, hospitals, guest houses, hotels, restaurants, etc.
