The given picture illustrates the design and the mechanism of a typical solar panel. Overall, the system consists of three main components including a square box with a see-through shield above and two pipes on the side.
Regarding the design, two tubes are placed opposite one another and both are attached to the side of the container. On top of it is a glass panel which is fixed to the four corners of the box.
In terms of the function, the cool air passes through the input and is trapped inside the box. It is then go through heat treatment using the high temperatures generated by absorbing the sunlight. The resulting gas is pushed out through the outlet at the final stage.
Similarly, the process is repeated to make warm water. However, a water pipe is installed systemetically int the box first. Then, the cool liquid runs inside the pipe through the input and flows along it into the box. The same warming process takes place and the product, which is warm water runs out through the outlput.
