The pictures illustrate the layout of the solar panel and the way to use it.
Overall, the solar panel is built with two different parts. In terms of its functions, it can be used to heat water as well as air. Moreover, during each process of heating air and water, there are two main stages, beginning with letting cool air and water in, and ending with warming such substances and let them out.
First, looking at the structure of the solar panel, it is a large, square box, with inlet and outlet. In addition, there is a transparent glass on top of that in order to preserve it in an optimal condition.
Turning to its use, first of all, it can be utilized to heat the air. This process starts by letting the cool air go through an inlet. Besides, heat energy from the sun rays are shown inside the box to make the air become hotter. Finally, the air which is warm can go out through an outlet and is ready to be used.
Another benefit of using the solar panel is to heat water. First, the cool water flows through an inlet to go into the pipe which is constructed inside the box. The pipe is also heated by the sun rays so that the temperature of the water can be higher. The final stage of this process is quite similar to the former one, with the fact that the warmer water is released from an outlet.
