[0002] As an important renewable energy device, photovoltaic array power generation components play a key role in the global energy transformation. With the continuous development of photovoltaic technology, its application in power supply is becoming more and more extensive, especially in areas with abundant solar energy resources. Photovoltaic array power generation systems have become a reliable energy solution. However, although photovoltaic technology has made significant progress, it still faces some challenges in practical applications, especially in improving power generation efficiency and extending equipment life.
