What’s the "Secret Weapon" of Aijiang Technology Behind Solving Complex PV Operation and Maintenance Challenges?

Amid the rapid growth of green energy, photovoltaic (PV) power stations are spread across the land like shining stars. However, the operation and maintenance (O&M) of PV power stations is no trivial matter; it directly affects return on investment and environmental benefits. Neglecting maintenance leads to declining annual power generation, frequent unexpected failures, and even potential safety incidents, turning "green investments" into heavy burdens. With deep insights into these issues, Aijiang Technology has developed a professional outdoor power station testing solution to solidify the foundation for the long-term value-added of PV assets.

Comprehensive Testing to Safeguard Power Station Health

During operation, PV power generation systems suffer from gradual efficiency losses due to natural environments, equipment aging, dust shading, and other factors. Aijiang Technology’s testing solution covers all-round inspection and maintenance of PV modules, brackets, inverters, cables, and other equipment.

Visual inspection of PV modules serves as the foundation. Our technicians carefully check for abnormalities such as cracks, hot spots, and discoloration. Broken glass or hidden cracks in PV cells may cause electric leakage and accelerate power attenuation; backsheet bulging, burn marks, loose sealing of junction boxes, and loose or corroded cable connections all threaten normal station operation.

Insulation resistance testing is essential. Regular measurement of insulation resistance to ground on DC and AC sides — even on cloudy days or at night when modules produce no current — helps detect insulation deterioration in a timely manner. If resistance falls below standards, we conduct sectional troubleshooting, focusing on cable damage and water ingress at connectors.

Hot spot detection is critical. A hot spot is local overheating of a module caused by cell cracks, internal connection failures, or severe shading. Using an infrared thermal imager, we accurately locate hot spots. Mild hot spots reduce power output, while severe ones can burn modules or even trigger fires. Once detected, we replace damaged modules immediately and analyze root causes to prevent recurrence.

Compliance with Standards & Customized Exclusive Services

Aijiang Technology strictly adheres to national standards including GB/T 50796-2012 Code for Acceptance of Photovoltaic Power Generation Projects and GB 50797-2012 Code for Design of Photovoltaic Power Stations, as well as international standards such as IEC 62446:2009, ensuring professional, standardized, and reliable testing services.

We also provide a customized service process: starting with customer consultation, followed by technical communication, solution design, scheme confirmation, production, commissioning and training, delivery and acceptance, and after-sales service. Every step is closely connected to tailor the most suitable testing solution for customer needs.
