Embodiment
[0067] When inspectors tested the inclination angle of photovoltaic modules in an agricultural-photovoltaic complementary photovoltaic power station in Shandong, the distance between the photovoltaic modules and the ground was as high as 3.5m, and it was difficult to test the inclination angle of photovoltaic modules using conventional test methods. When testing the inclination angle of photovoltaic modules, the roof is difficult to climb, and it is difficult to test the inclination angle of photovoltaic modules using conventional testing methods with an inclinometer. These two tests finally use this method to test the inclination angle of photovoltaic modules with drones, and the test efficiency is high.
[0068] UAV testing can quickly obtain the module inclination angle of the entire photovoltaic array to be tested, and can realize the measurement of the inclination angle of photovoltaic modules in complex environments.
[0069] To sum up, the present invention is a photovo...
