The diagrams depict the structure of solar panel and also explain how its usage.Overall, the first picture depicts a layout of the solar panel in order to help consumers know more about how it looks and well as know a function of each parts, while the remaining two pictures show the usage of its.
The first picture depicts the solar panel, it contains two parts, including a square box a, which is attached with a thin pipe and a transparent in top of that box.
The subsequent picture reflects the function of the solar panel in term of creating warm air. The sun rays-heat energy shine on a transparent top. This transparent collects sun rays to make the inside of the box hotter. The thin pipe is called inlet and outlet have a responsibility to turn cool air into warm air.
The final picture demonstrates how to generate warm water. Using the same way with the creating warm air. Firstly, the transparent top gathers rays from the sun to make the box warmer, even hotter. Unlike the process of generate warm air, inside the box has a water pipe, which already connected with inlet and outlet. Cool water flows into a inlet and is transferred by a water pipe into the outlet pipe to make water warmer.
