FIELD OF INVENTION

[0001] The embodiments herein generally relate to solar water heating systems. More specifically, the invention provides a solar water heating system for providing maximum amount of hot water.

BACKGROUND AND PRIOR ART

[0002] In conventional solar water heating apparatus, water in the solar collector gets heated due to solar radiation and the same is stored in a thermal insulated tank which is placed above collector tubes or plate, and the same is used next day morning. If the water is used in between before next morning, then again cold water get refilled and the temperature may not be maximum for the next day use.

In addition to that, the hot water tank capacity is also designed according to the heating capacity of the solar thermal collector. Once the hot water is taken out from the tank again the cold water get refilled to the tank and hence the temperature get reduced. There may not be sunlight available to heat up the refilled cold water in the early morning. To overcome this, the water has to be refilled only when the tank is fully drained or the temperature is more than the required level. This is difficult to achieve manually.

[0003] Therefore, there is an unmet need for a system and a method that can provide maximum amount of hot water automatically.
