The given diagram illustrates the functioning of a solar panel used for producing electric energy for both air and water heating. Overall, it can be seen that is a physical process that involves mainly solar irradiance for producing energy.

To begin, the first picture displays the solar panel consisting of a metal box on which a transparent surface is placed; on the left and right sides of the box two pipes protrude, which are the inlet and the outlet pipes, respectively.

The second illustration shows how the panel is used to heat air. Firstly, cool air enters the panel through the inlet pipe. At this stage, the Sun Rays- which is called in physics heat energy- hit the transparent top warming up the air inside. After that, air comes out of the outlet pipe, ready to be used for domestic purposes, such as heating the building.

The third image displays the process of heating water, which is very similar to the previous one. As cool water gets into the panel through the inlet pipe, it is channeled into the Water Pipe; here the sun rays heat the transparent box and thus it warms up the water pipe and the water in it. The warm water is then forced out through the outlet pipe as it is ready for use.
