Solar energy harvesting devices are widely used in smart agriculture nowadays. However, when lighting conditions are weak, such as through the night or on cloudy days, efficiency decays a lot. Additionally, as time goes by, more and more dust and bird droppings accumulate on the panel, which decreases the performance significantly. This paper aims to overcome the disadvantages mentioned above, and a novel wind-solar hybrid energy harvesting approach is proposed with an oscillation-induced dust-cleaning function. A wind-induced vibration device is specially designed in order to generate electrical energy and/or clean the photovoltaic panel. While in good lighting conditions, the device could keep the panel in a stable state and optimize the photovoltaic power generation efficiency. Such a hybrid energy harvesting approach is called a "suppress vibration and fill vacancy" algorithm. The experimental platform of the proposed device is introduced, and both experimental and simulation results are attained, which prove that using this device, we could realize multiple purposes at the same time.
太阳能收集装置如今在智能农业中被广泛应用。然而，当光照条件较弱时，比如在夜间或阴天，效率会大幅下降。此外，随着时间的推移，越来越多的灰尘和鸟粪会积聚在面板上，这会显著降低其性能。本文旨在克服上述缺点，提出了一种具有振荡诱导除尘功能的新型风光混合能量收集方法。专门设计了一种风致振动装置，以便产生电能和/或清洁光伏面板。在良好的光照条件下，该装置可使面板保持稳定状态并优化光伏发电效率。这种混合能量收集方法被称为“抑制振动并填补空缺”算法。介绍了所提出装置的实验平台，并获得了实验和模拟结果，这些结果证明使用该装置可以同时实现多种目的。
