Advantages explained

> They can be used throughout the year to boil waters and are therefore of extreme significance in colder countries where the householders require warm water for a host of purposes like bathing, washing, cooking, cleaning, drinking, etc.

> They do not require any significant maintenance cost and hence the cost of running is pretty low

> The panels are strong and resistant to wear and tear. This is also due to the fact that there are not many moving parts and hence, the mechanical depreciation is low.

> They are durable and have a long life of over 20 years.

> They fall under the sustainable form of technology and are environmentally friendlier than most conventional energy resources.
