Why Solar Water Heater?

Solar water heating system
A solar water heating system is a device that uses the sun's energy to heat water. This energy is completely free. Solar energy (sunrays) is used to heat water. Water is easily heated to 60-80o C. A range of Solar Water Heaters (SWHs) with a capacity of 100-300 liters are suitable for solar water heater domestic use. Large systems can be used in restaurants, canteens, guest houses, hotels, hospitals etc. A 100 liter capacity SWH can replace an electric geyser for domestic use and save around 1500 units of electricity per year. The use of 1000 SWHs of 100 liter capacity each will contribute to approximately 1 MW of peak load savings. A SWH with a capacity of 100 liters can prevent 1.5 tonnes of carbon dioxide emissions per year.

Working of Solar Water Heater
The sun's rays fall on the collector array (a component of a solar water heating system). A black absorbent surface (absorber) inside the collectors absorbs solar radiation and transfers heat energy to the water flowing through it. Hot water is collected in an insulated tank to prevent heat loss. Water circulation from the tank through the collectors and back to the tank continues automatically due to the thermo siphon system. Based on the collector system, solar water heaters can be of two types: A solar water heater consists of a collector that collects solar energy and an insulated storage tank to store hot water. The stored hot water can be used at any time later.
