Nenghuanbao: Quality Protection in the Photovoltaic Industry: Beware of the “Invisible Killers” and Build a Bright Future Together
As the global energy transition progresses, the photovoltaic industry is experiencing remarkable growth, with an annual increase exceeding 20%. According to the latest data from the National Energy Administration, by the end of 2024, China’s installed photovoltaic capacity will surpass 887 million kilowatts. However, within this thriving sector, serious quality issues lurk, such as “substandard components” and “reduced lifespan of power stations.” When photovoltaic panels atop factory roofs become safety hazards, and profits are diminished due to inferior products, how can we protect these precious “sunshine revenues”?
The Hidden Costs: The Butterfly Effect of Low-Quality Components
A painful lesson from a distributed photovoltaic power station serves as a warning: an array that met power generation standards during acceptance testing experienced a 12% power degradation after enduring three seasons of weather. Investigations revealed that inadequate weather resistance in the backsheet material caused PID effects, while early yellowing of the EVA film led to delamination. These defects, difficult to detect with the naked eye, acted like time bombs, turning a 25-year warranty into a mere illusion. Even more alarming is the industry’s “gray production chain”: small workshops use B-grade solar cells to pass off as A-grade products, and backsheet materials made from recycled materials fail to meet the required ultraviolet resistance standards, showing PID phenomena within three weeks during humidity tests. Such unreliable “photovoltaic knockoffs” are eroding the credibility of the entire industry.
Three Layers of Protection: Establishing a Quality Firewall
Traceability Certification System: High-quality components carry a “genetic code,” with traceable records from silicon purity to cell conversion efficiency and packaging material transparency. Products can obtain TÜV Rheinland PID test reports, CSA salt spray certifications, and other eight international certification documents.
Comprehensive Testing Mechanism: Leading companies have established numerous quality inspection processes, from micro-crack detection to hot spot location. For instance, bifacial modules must undergo full-scene simulation certification from the National Photovoltaic Quality Inspection Center (CPVT), the only authoritative platform in China covering the entire photovoltaic industry chain. This institution simulates extreme conditions (-40°C to 85°C) in laboratories to verify module reliability. The mechanical load testing (±5400Pa) and ultraviolet aging test standards of leading manufacturers have also surpassed basic IEC requirements.
Smart Operation and Maintenance Assurance: Utilizing digital tools such as IV curve diagnosis and drone infrared inspections can promptly identify component defects. Nenghuanbao’s self-developed NiOS™ smart energy management system integrates cloud computing, big data, and artificial intelligence technologies to achieve 24/7 real-time monitoring, significantly reducing fault diagnosis and response times while enhancing operational efficiency.
Joint Industry Governance: Illuminating Every Step
To combat the market of counterfeit components, regulatory authorities have established a photovoltaic “identity card” system, requiring each module to be coded upon storage. Statistics from third-party organizations indicate that photovoltaic power stations using high-standard components can reduce LCOE by 0.12 yuan per kilowatt-hour over a 25-year period. As green power plants become a central theme of our time, selecting reliable photovoltaic products is not only a responsible choice for one’s assets but also a contribution to the commitment to carbon neutrality. Let us use our expertise to cut through market confusion and protect this “sunshine contract”—because every watt of clean electricity deserves serious consideration.
