Photovoltaic Power Generation
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.
