Mr. Chen, the reliability testing manager of a global top 3 photovoltaic enterprise, has a deep understanding of this: "To strive for the highest level of TUV Rheinland component certification, we need to complete 10,000 hours of continuous stability testing." However, the traditional simulator had only been running for 3,000 hours when the light intensity drift exceeded 8%, and the spectral matching degree directly dropped to grade B. The initial 2 million yuan testing cost and six months of time were all wasted. What is even more fatal is that the 210mm+ super-large size components were tested in sections, and the splicing error made the certification data not recognized by international institutions at all, causing repeated setbacks in export orders.
The "Long-Term steady-state core technology" of Saifan's 3A-level solar simulator has completely ended this predicament. The equipment is equipped with the 8th generation steady-state drive system. Through constant current and constant voltage dual closed-loop control +AI adaptive compensation algorithm, the current stability is precisely controlled within ±0.005%. Equipped with a military-grade dual-circulation water cooling system, the temperature control accuracy reaches ±0.05℃. Even after continuous operation for 10,000 hours, the light intensity drift remains ≤±1.5%, and the spectral matching degree is always stable at over 97%, far exceeding the IEC 60904-9 3A standard. What is even more worth mentioning is that its 3.2m×5.0m ultra-large format uniform light system can fully cover 210mm+ ultra-large size components at one time, with zero splicing error. The test data has been 100% reviewed by international institutions such as TUV, UL, and IEC, making the component certification process smooth sailing.
"Now, with the 10,000-hour long-term certification passed at one go, the component premium has directly increased by 15%, and the annual new revenue exceeds 600 million yuan!" " Engineer Chen couldn't hide his joy. "The equipment also supports intelligent switching between xenon lamps and LED dual light sources. The xenon lamp for high-end certification (with a spectrum infinitely close to natural sunlight) and the LED for mass production inspection (with a lifespan of up to 100,000 hours) can be selected as needed, significantly reducing costs." Moreover, the intelligent calibration system automatically calibrates every 100 hours and can also be linked with photovoltaic testing software to automatically generate certification reports. Compared with imported equipment, it saves 6 million yuan and can be delivered within 45 days. The entire certification process is accompanied by technical experts. Domestic equipment has completely broken the international monopoly!"
