What is a solar water heater?
It is a device that uses Sun energy to make water hot for bathing, cleaning, washing etc... It is installed at the roof top where proper sunlight is available.
What are different types of solar water heaters?
It has 2 major types- one is based on flat-plate collectors (FPC) and the other is based on evacuated tube collectors (ETC). Flat-plate collectors are durable because they are of a metallic type. Glass is used for ETCs which is fragile in nature.
Which Type is better for different places?
ETCs are cheaper than FPCs. They perform better in the colder regions by avoiding freezing even the temperature goes sub-zero. FPCs are also used in the colder region but they are costly than ETCs.
If your area has hard water, make sure to install an FPC system with a heat exchanger as it will avoid scale deposition in copper tubes of solar collectors. An ETC system doesn't need heat exchanger but it needs cleaning at least once in a year to remove salt deposition.
Do I get any subsidy to install the system?
No, you can't. Such systems have no subsidy.
How do I decide about the size or capacity required to be installed?
