Liu, the head of the certification center of a leading photovoltaic enterprise, has repeatedly encountered obstacles in obtaining international module certifications: "We are striving for the highest level of TUV Rheinland module certification and need stable lighting conditions to complete a 10,000-hour reliability test." However, after the traditional simulator had been running for 2,000 hours, the light intensity drift exceeded 8%, and the spectral matching degree directly dropped to grade B. The initial 2 million yuan in testing costs and six months of time were all wasted. What is even more troublesome is that outdoor tests are affected by rain and temperature differences, resulting in large data dispersion and are not accepted by international institutions at all. As a result, export orders have been repeatedly frustrated.
The implementation of Saifan Optoelectronics' 3A-level steady-state solar simulator has completely broken through this predicament. This device 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. For super-large-sized components, a 3.2m×5.0m super-large format uniform light system can also be customized to fully cover 210mm+ components at one time, with zero splicing error and 100% test data passing the review of international institutions such as TUV and UL.
"With Saifan's solar simulator, we passed the 10,000-hour long-term certification in one go. The premium of our components increased by 15% directly, and our annual new revenue exceeded 600 million yuan!" " Engineer Liu happily shared, "The equipment also supports intelligent switching between xenon lamps and LED dual light sources. The xenon lamps used for high-end certification ensure the accuracy of the spectrum, while the leds used for mass production inspection reduce energy consumption, saving over 300,000 yuan in electricity fees annually." Moreover, the intelligent calibration system automatically calibrates every 100 hours and, in conjunction with the photovoltaic testing software, automatically generates certification reports. Compared with imported equipment, it saves 6 million yuan and can be delivered within 45 days, completely breaking the international monopoly.
