The diagrams illustrate the basic structure of a simple solar panel, and the process of warming either air or water using an energy from the sun.
Overall, this technology consists of transparent glass top where water or air can be heated by sun rays, beginning with their entrance through an inlet and ending with warm air or water from an outlet.
Initially, cool air enters through the inlet, where it exposed to solar radiation inside the box. As sun’s rays transformed into temporal energy, the air warms and exits through the outlet. Similarly, in the second process, cool water passes through the inlet that share solar lights to internal surface, making warm water and it flows through the outlet.
