Industrial Solar Rooftop
A solar water heater is a device that captures sunlight to heat water. It can be an economical way to generate hot water for your family for shower and bath.
Solar water heater not only enables substantial energy savings as solar power is free in contrast to natural gas or fuel oil. Moreover, it is a way to produce hot water for sanitary use throughout the year without emitting any CO2.
The system installed on a terrace or open space where it can get sunlight and the energy from the sun is then used to heat water and store it in an insulated tank. The system is not connected to electricity supply and thus does not have an on-off switch, but it uses the sunlight throughout the day to heat the water and store it in the storage tank.
Most of the solar water heater on a sunny day can provide heater water at about 68° ±5° C temperature. Water from the storage tank can then be used for any application as desired.
When there is insufficient sunlight, the water is preheated and a back-up system takes over to bring the water to the required temperature. This system can be used at a constant temperature throughout the year.
