Strict Quality Control as the Foundation for High-Quality Development of Solar Carports

Guided by the "dual carbon" goal, solar carports, as an innovative carrier integrating clean energy utilization and green travel, are rapidly being integrated into urban infrastructure and park supporting systems. They offer multiple values, including sun and rain protection, photovoltaic power generation, and space efficiency. Quality control, as a core link in ensuring functional reliability and long-term benefits, directly impacts the industry's sustainable development.

Quality control for solar carports must be implemented throughout their entire lifecycle, anchoring the principle of "safety first, efficiency matching" from the design stage. Structural mechanics calculations must be accurately verified in conjunction with local meteorological data (such as maximum wind load and snow thickness) to avoid short-sighted designs that prioritize power generation over load-bearing capacity. Photovoltaic module selection must strictly adhere to international standards such as IEC, focusing on verifying key parameters such as conversion efficiency degradation rate and temperature coefficient to prevent inefficient or falsely labeled products from entering the market. Electrical systems must strengthen insulation protection and lightning protection grounding design to reduce the risk of leakage and short circuits from the source.

The manufacturing process is a crucial line of defense for ensuring quality. Steel welding requires 100% flaw detection to ensure weld strength meets GB/T 12467 requirements; the thickness of the galvanized layer and coating adhesion of the photovoltaic bracket must be verified for corrosion resistance through salt spray testing; during the module encapsulation process, the cross-linking degree of the EVA film and the anti-aging performance of the backsheet must be monitored to avoid hidden cracks, delamination, and other potential problems. On-site installation requires even more detailed process control: the foundation pouring must be checked for levelness and the positioning accuracy of embedded parts; bolt tightening torque must be fully verified according to design values; the photovoltaic array arrangement angle must be optimized in conjunction with latitude to reduce power generation loss caused by shading.

A closed-loop quality system is equally essential during the acceptance and operation and maintenance phases. Before grid connection, insulation impedance testing, inverter efficiency testing, and continuous 72-hour trial operation must be completed to ensure that power generation and stability meet standards; during the operation and maintenance phase, a regular inspection mechanism should be established, focusing on monitoring issues such as module hot spots, bracket deformation, and cable aging, and using an intelligent monitoring system to provide real-time early warnings of anomalies, minimizing fault response time.

Currently, with technological iteration and market expansion, the quality control of solar carports has shifted from "passively meeting standards" to "proactively leading the way." Only by establishing stringent standards for every process and covering all aspects of design, production, installation, and operation with a holistic approach can this green facility truly become a safe, reliable, and long-term value-added "sunshine asset," providing stronger support for energy transition and low-carbon living.
