The diagram demonstrates the structure, working principle and the use of solar pannel. Solar panel is made into a box like structure where the internal process takes place which actually convert sunlight received from sun into usable form of energy for different purposes.
The working principle of solar panel is straightforward, where the cold air is converted into warm air. Additionally, there are two openings in the box which alows the air to get inside as cold air and move outside as warm air. In procedure, firstly, the cold air gets inside the solar panel, while top layer of the panel made up of a transparent material where UV rays from sun falls on the box and air inside the box gets heated and produce warm air, which could be collected on the other end of the box.
The working principle of solar water heater is similar to that of Solar heat air, In this process, there are some additional features involved in converting the cold water into warm water. Initially, Cold water enters into the heater and it runs through a cable known as water pipe which is connected to other end of the box, where hot water is collected. In this, the use of cable is vital because, sun rays falling directly on the box won’t allow the water to get heated evenly but, when water running through cable the heat is transferred evenly, and will provide a good warm water.
