A Solar water Heater is a device which provides hot water for bating, washing, cleaning, etc. using solar energy. It is generally installed on the terrace or where sunlight is available and heats water during day time which is stored in an insulated storage tank for use when required including morning.
A solar water Heater comprises of an array of solar collectors to collect solar energy and an insulated tank to store hot water. Both are connected to each other. During day time, water in solar collectors gets heats which is either pumped or flown automatically on thermosyphon principle to the storage tank. hot water is then stored in the tank which can be used for various applications.
A 100 liter per day capacity system suitable for 3-4 people can save up to 1550 units of electricity in a year, depending on hot water used. Higher capacity systems will save higher amount of electricity besides reducing higher amount of Green House Gas (GHG) emissions. Electricity is expensive and is not available due to power cuts in many areas when required for heating water.
On cloudy days also, if it is for a day or two, you still get warm water as water gets heated due to diffused radiation available in the atmosphere. The system, however, is either connected to an electric geyser in the house or an electrical back-up is provided in the storage thank of the system which is switched on when water is not sufficiently hot. So, you get hot water all the time even on rainy days.
For a house with one bathroom and 3 to 4 member, 100 liter per day capacity system should be sufficient. For more numbers of bathrooms, the capacity will increase accordingly due to pipe losses & more number of family members. generally the capacity is decided based on hot water required in morning for bathing. If the usage is in evening & at other times also, the capacity is decided accordingly.
