The image illustrates the building of solar power machine and how it works.
Overall, a simple solar panel is formed of a metal box-like structure which has an inlet and an outlet covered with a transparent glass. As it is shown in the diagram, it is a simple product not complicated.
There are two types of devices that operate on solar energy, the first one produces warm air in which it absorbes sun rays and transforms natural air into warm air. In this kind, the panel is empty, filled only with air.
The second type of this device converts normal water into hot water. Whereby, the water enters the board, and then it heats and turns into hot water that can be used in different ways. The operation starts with fluid enetering the solar machine through the input, then it remains for a while inside it transforming into hotter water and then it exits it throughout the output into its final destination.
