流程图
The diagrams show the structure of solar panel and their use.
Summarize the information by selecting and reporting the main features, and make comparisons where relevant.
1、题目大意
图表显示了太阳能电池板的结构及其用途。
这道题目其实并不能算传统意义上的流程图，因为二三图之间并没有前后顺序关系，文章可以分为三段，第一段改写题目+概括趋势，第二段描述装置样式，第三段解释加热空气和水的过程。

The charts illustrate the characteristics of solar panels and two possible uses. Firstly, the basic structure of a solar panel is shown, then how the warming process of air or water works.
主体段-1：描述太阳能板的结构
In terms of structure, the first diagram shows that a solar panel consists of a box with an inlet on one side and an outlet on the other. The box is covered by a transparent glass panel, which seals it while allowing sunlight to penetrate and trap heat.
主体段-2：描述加热空气和水的过程
The second and third diagrams illustrate the solar panel's functionality in heating both air and water. The first use of the solar panel is to generate warm air. This process works by allowing air to enter the box through the inlet; once inside, the air heats up as sunlight penetrates the transparent glass, creating warmer air that flows out through the outlet. In contrast, heating water requires an additional component: a tube connecting the inlet and the outlet, allowing water to flow through it. As with the air-heating model, sunlight passes through the transparent top, warming the water inside the tubes. Cool water enters through the inlet pipe, absorbs heat as it flows through, and exits as warm water through the outlet.
