Mr. Chen, the reliability testing manager of a global top 3 photovoltaic enterprise, was once worried
about his attempt to obtain the highest-level component certification from TUV Rheinland. We need
to conduct stable tests for 10,000 consecutive hours. However, after the traditional simulator has been
running for 3,000 hours, the light intensity drift exceeds 8%, and the spectral matching degree drops
to grade B. The initial investment of 2 million yuan in testing costs and six months has all been wasted.
What is even more troublesome is that the splicing error in the segmented testing of 210mm+ super-large
size components makes the certification data not accepted by international institutions at all.
The "Long-Term steady-state core technology" of Saifan's 3A-level solar simulator has completely solved
the certification problem. The equipment is equipped with the 8th generation steady-state drive system,
featuring constant current and constant voltage dual closed-loop control. The current stability is ≤±0.005%,
and it is combined with a military-grade dual circulation water cooling system (temperature control accuracy
±0.05℃). After continuous operation for 10,000 hours, the light intensity drift is ≤±1.5%, and the spectral
matching degree always remains ≥97%. Far exceeding the requirements of the IEC 60904-9 3A standard.
Equipped with a 3.2m×5.0m ultra-large format uniform light system, it can 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.
"Now, the 10,000-hour long-term certification is passed in one go, the component premium has increased
by 15%, and the annual new revenue exceeds 600 million yuan." " Engineer Chen expressed his joy, saying,
"The equipment supports dual light source switching between xenon lamps and leds. Xenon lamps are used
for high-end certification (with a spectrum closer to natural sunlight), and leds are used for mass production
testing (with a lifespan of up to 100,000 hours). Choosing as needed is more cost-effective." Moreover, the
intelligent calibration system automatically calibrates every 100 hours and can also be linked with photovoltaic
testing software to 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 support.
Domestic equipment has completely broken the international monopoly."
