The image presents three diagrams showcasing a solar panel's structure and function: the top diagram identifies a basic solar panel comprising a transparent glass layer positioned over an enclosed box featuring an inlet on one side and an outlet on the other. Below, two separate diagrams illustrate operational uses—the first one involves using air indicated by the inlet directing air into the box, whereupon exposure to sun rays results in the output of warm air via the outlet, suggesting air heating application; the second diagram depicts the use with water, demonstrated by water entering through the inlet, subsequently being heated by sun rays within coiled tubes, and exiting as warm water from the outlet, indicating water heating application. Both bottom diagrams highlight processes driven by received sun radiation as depicted by a sun icon.

The diagrams illustrate the structure of a simple solar panel and how it is used to heat air and water.
Overall, the solar panel has a straightforward design with only a few components, and it uses energy from the sun to warm either air or water as they pass through the system.
In terms of structure, the panel is shaped like a rectangular box and is covered on the top by a layer of transparent glass. This glass surface allows sunlight to enter the panel while helping to trap heat inside. On two opposite sides of the box, there is an inlet and an outlet, which enable air or water to flow through the panel during operation.
Regarding its use, the system works by absorbing solar energy. When sunlight passes through the glass cover, the heat is retained within the panel. If air enters through the inlet, it is gradually heated as it moves inside and then leaves the outlet as warm air. In a similar way, when water flows through the panel, it absorbs the heat from the sun and is released as warm water.
