As the core of solar power generation systems, photovoltaic panels are widely used on the roofs of residential, commercial and industrial facilities, as well as large-scale solar power stations.

[0003] Photovoltaic panels operate on the principle of the photoelectric effect, which occurs when photons hit semiconductor materials, releasing electrons to generate an electric current. To ensure efficient operation, photovoltaic panels are equipped with inverters designed to convert direct current into alternating current so that they can be smoothly connected to the power grid or meet the electricity needs of homes and businesses.
