Band 6+: The diagrams show the structure of the solar panel and its use. Summarize the information by selecting and reporting the main features, and make comparisons where relevant.

The given diagrams illustrate the structure of the solar panel and how it is using to heat air and water.

In general, the solar panel has a simple structure with several parts inside a box with a clear top. The diagrams also show how air and water are heated by solar panel.

The outside of the panel has an intake and an outlet. On the top, the surface is transparent in order to receive sun rays (heat energy). When using to heat air, cool air passes through the inlet and goes inside the box. At this stage cool air being heated up by sun rays as the clear top let heat energy pass by. Then warm air comes out at the outlet.

When using to heat water, however, there is a small difference in structure. It is a pipe that connect the intake and the outlet inside the box. As water passes through the pipe, it will gradually heat up in the same way thai air is heated up in the previous paragraph. After that warm water exit at the outlet and ready for use.
