The given diagrams describe the structure and uses of solar panel. Here the solar panel is used to heat air as well as to heat water.
Firstly, a box should be used which has both inlet and outlet. Later, transparent top is installed upon the
box. Now, for generating hot air, the box is placed in sunlight. Cool air gets in through inlet. The sunrays converts into heat energy which turns cool air into hot air. Finally, warm air comes out through outlet.
Even to heat water, the same box with transparent top is used. However, a water pipe is added connecting both inlet and outlet. The heat energy produced by sunlight converts normal water into warm water which exits from the outlet.
These pictures represent, the requirements for solar panel and process of converting sunrays into heat energy along with two real life examples, like heating water and generating hot air.
