Description

Technical Field

[0001] The utility model relates to a photovoltaic panel experimental device, in particular to an experimental device for the influence of light intensity and angle on photovoltaic power generation. Background Art

[0002] With the continuous growth of global energy demand and the call for environmental protection, the application prospects of photovoltaic power generation technology in energy production are very broad, and photovoltaic power generation will become an important part of global energy supply in the future. In photovoltaic power generation technology, light intensity and angle are key factors affecting the power generation of photovoltaic panels. The stronger the light, the higher the power generation of photovoltaic panels; the weaker the light, the lower the power generation of photovoltaic panels; the power generation efficiency of photovoltaic panels is also affected by the angle of light. Generally speaking, the power generation efficiency of photovoltaic panels is the highest when facing the sun, and when the angle of sunlight increases, the power generation efficiency will gradually decrease.

[0003] In photovoltaic power generation experiments, the specific effects of light intensity and angle on photovoltaic power generation need to be intuitively displayed through experimental equipment. However, most of the current experimental equipment directly adjusts the angle of the photovoltaic panel and the intensity of the light source to conduct experiments. It is inconvenient to measure the tilt angle and orientation angle of the photovoltaic panel, resulting in a lack of data support and control effect in the experiment. In addition, the adjustment of the photovoltaic panel is not convenient, so it is urgently needed to be improved. Utility Model Content

In the experimental equipment of the present scheme for the influence of light intensity and angle on photovoltaic power generation, the influence of light intensity on photovoltaic power generation can be obtained by adjusting the light intensity of the light lamp during the experiment. The photovoltaic panel is driven to rotate by the angle adjustment mechanism to adjust the tilt angle of the photovoltaic panel.

[0066] The turntable 9 is driven to rotate by the azimuth adjustment mechanism, and the turntable 9 drives the photovoltaic panel 6 to rotate to adjust the orientation of the photovoltaic panel 6. When the photovoltaic panel 6 faces different orientations, the degree of absorption of light energy is different. In this process, the orientation angle value of the photovoltaic panel 6 is measured by the azimuth angle detector (that is, the angle value of the orientation of the photovoltaic panel 6 is measured by the cooperation of the pointing rod 19 and the protractor 18). At the same time, by observing the value change of the ammeter 3, the influence of the orientation angle of the photovoltaic panel 6 on photovoltaic power generation is directly obtained, so as to obtain the influence of the photovoltaic panel 6 on the degree of absorption of light energy when facing different orientations.
