The process diagram depicts the main features of solar panel and its functionality for heating water and air.
Overall, it is evident that, solar panel has a simple structure with only a few components. Besides, it runs by using the power of the sun in order to heat water and air.
According to the diagram, solar panel is made of a box with a transparent top which attractc heat energy from the sun rays for heating water and air. Moreover, a rectangular shape with the entrance of inlet and outlet on either side of it.
Regarding the operation, at first, cool air comes into the panel among inlet pipe. Sun rays are absorbed in order to heat the air. Afterwards, warm air could be released by outlet tube. In terms of heating water, the first stage is related to delivering cool water into the panel by inlet. Then, sun rays are attracted by a transparent top for heating water flow in water pipes. After that, warm water exists through an outlet.
