Quzhou, Zhejiang: Power Inspections Enhance Efficient Operation of Photovoltaic Power Stations

"The professional guidance from the power supply company has helped us eliminate safety hazards. You have also taught us equipment maintenance techniques. This ‘power escort’ makes the operation of our power station much more reliable!" said Xu Jian, head of the Yanwashan Photovoltaic Power Station in Changshan, Zhejiang, on March 3, to the operation and maintenance personnel from State Grid Quzhou Power Supply Company who came to conduct a "regular check" on the equipment.

Recently, as temperatures rise and the weather improves, photovoltaic power generation has entered a “golden period”. To ensure the stable operation of county-level photovoltaic power stations, the State Grid Quzhou Power Supply Company has organized operation and maintenance teams to conduct specialized equipment inspections and provide technical assistance at various photovoltaic power stations across the county. This measure ensures that the stations can meet peak power generation demands under optimal conditions.

“Spring winds and dust can easily lead to dirt accumulate on equipment. Timely cleaning can improve the conversion efficiency of photovoltaic panels by more than 5%,” explained the operation and maintenance personnel at the Yanwashan Photovoltaic Power Station. They conducted a thorough inspection of key equipment, including photovoltaic panels and box transformers. Issues such as loose bolts on two photovoltaic panel mounts and dust accumulation on an inverter heat sink were promptly addressed on-site. The team also guided the station’s staff on optimizing equipment inspection strategies.

State Grid Quzhou Power Supply Company will continue to deepen its collaborative management mechanism for the green development of clean energy. It will provide specialized technical assistance services to 22 photovoltaic power stations within the county and use a digital monitoring platform to track real-time operational data. Additionally, they will carry out regular “one-on-one” guidance to provide stronger technical support for the green transformation of the county’s economy. (Written by Dong Ruiheng)
