Exhibit Explanation:

展品模拟太阳光穿越大气层和云层时太阳能量的变化。遮光片代表太阳照射地球需要经过大气层和云层的阻挡，大气层阻挡率为10%，云层阻挡率为5%。当用不透明物体挡住灯光时，没有光的照射，这时光伏板不输出电能。可以直观看到光伏发电,同时展示太阳光的强弱和电力输出大小的关系。

The exhibit simulates the changes of the solar energy when sunlight passes through atmospheric layer and clouds. The shading represents the obstruction that sunlight needs to pass through in the atmospheric layer and clouds when shining the earth. The obstruction rate of atmospheric layer is 10% and that of clouds is 5%. When non-transparent object is used to keep off lighting, the photovoltaic panel doesn’t export electric energy without the irradiation of light. Photovoltaic power generation is demonstrated through the device the relationship between sunlight intensity and quantity of the electric output is also observable.
