In 2025, the photovoltaic industry will enter the "large-size era", with the capacity of 210mm silicon wafer modules exceeding 60%, and 182mm modules becoming the market mainstream. Even 240mm ultra-large modules have been used for ground power stations. Simultaneously, the detection challenges have become increasingly prominent: traditional small-area simulators require multiple joint tests, with data deviations exceeding 2.5%; devices such as xenon lamps have problems like light intensity drift and short lifespan, unable to meet the "one-time detection, precise full coverage" requirements for large-size modules. More seriously, the IEC 60904-9 international standard has stricter requirements for the uniformity and stability of large-area simulators, with imported equipment priced over 2 million, making most enterprises hesitate.
Beijing Saifan Optoelectronics, with 22 years of experience in photovoltaic detection, accurately grasps industry trends, integrates LED light source technology breakthroughs and large-area optical design, and launches the SS-8000 series large-area 3A level LED steady-state solar simulator - with the irradiation area reaching up to 1200×1500mm, the three core indicators fully meet the 3A standard. With the core advantages of "super large coverage, long-term stability, and green energy conservation", it solves the pain points of large-size module detection and becomes the preferred equipment for photovoltaic production lines, research institutions, and third-party certifications.
1. Core breakthrough: Large-area + LED dual empowerment, 3A standard not discounted
Saifan's SS-8000 series breaks traditional design and achieves "a perfect balance between large-area and high precision", while leveraging the natural advantages of LED light sources, redefining the large-size detection experience:
Super large-area precise coverage: 1200×1500mm, uniformity ≤ 1.8%
Innovatively adopts "distributed LED array + ultra-hemispherical collimating lens" design, with the irradiation area customizable (from 600×800mm to 1200×1500mm), fully covering the detection requirements of 210mm, 240mm, etc., and aerospace-grade solar panels. Through the optimization of LED lamp bead arrangement using the simulated annealing algorithm and the double-integration sphere uniform light technology, the uniformity of the entire irradiation area ≤ 1.8%, edge and center light intensity deviation ≤ 0.5%, far exceeding the IEC 60904-9 3A standard (≤ 2%), completely getting rid of the error troubles of joint tests.
LED light source long-term stability: lifespan over 20,000 hours, stability ≤ ±0.3%/h
Using high-power vertical structure narrow-band LED light sources to precisely reproduce the AM1.5G standard spectrum (300-1100nm), with a spectral matching coefficient of 0.80-1.20, fully meeting A-level requirements, especially suitable for the spectral response characteristics of perovskite, HJT, etc. LED light sources naturally have the advantage of low attenuation, with an irradiation stability of ≤ ±0.3%/h for 72 hours of continuous operation, short-term stability (STI) ≤ 0.2%, core component lifespan over 20,000 hours, which is more than three times that of traditional xenon lamp equipment, and annual maintenance costs reduced by 60%.
Green energy conservation + intelligent light control: energy consumption reduced by 50%, zero operation threshold
Compared with traditional xenon lamp equipment, LED light sources' energy consumption drops by 50% (operating power is only 800W, while xenon lamp equipment is generally over 2000W), without infrared band peak heating, the temperature rise in the detection area is ≤ 3℃, avoiding the impact of high temperatures on test accuracy. Equipped with a closed-loop intelligent light control system, it supports adjustable light intensity from 0.3-1.2S0, capable of simulating different regional sunlight conditions; Deeply integrated with the SpectraSmart Professional Edition software, it can complete "light intensity calibration - IV scanning - defect identification - report generation" with one click. It has 15 + industry standard templates built-in, and the data can be directly connected to the TÜV and UL certification systems, ensuring compliance without worries.
II. Scene Enabling: From production lines to aerospace grade, covering all dimensions of large-sized requirements
Relying on the advantages of large surface area and the stable characteristics of LEDs, the Sifan SS-8000 series has deeply served multiple fields and become the "precise detection core" for different scenarios:
Large-sized component production: One-time detection, efficiency increased by 60%
A leading photovoltaic enterprise in Jiangsu Province used the SS-8000 to build an automated detection line for 210mm components. The irradiation surface of 1200×1500mm can cover the entire component at once. The single-component detection time was reduced from the traditional 15 minutes to 6 minutes, and the daily detection volume increased by 60%; The equipment can automatically identify component cracks, broken grids, etc., combined with AI visual analysis technology, the defect identification accuracy rate reached 99.8%, the factory qualification rate increased to 99.97%, and the annual loss was reduced by over 8 million yuan.
Research and aerospace: Adapted to super-large devices, data repeatability 99%
The Chinese Academy of Sciences Space Center selected the SS-8000 customized version (1500×2000mm) for satellite solar panel electrical performance testing. Its 350-1800nm wide spectral coverage (optional) and ±3° collimation light beam characteristics perfectly meet the requirements of aerospace AM0 standard, and the test data deviation from the space environment is ≤1%; Tsinghua University used it to conduct large-sized perovskite component stability research. With a short-term stability of ≤0.2%, it successfully captured the efficiency attenuation difference at the edge and center of the component, and the experimental period was shortened by 40%.
Third-party certification: Authoritative compliance, reports globally recognized
Many third-party testing institutions such as Beijing Jianheng and Shandong Huiting have used the SS-8000 as the benchmark equipment for large-sized component certification. Its CNAS accreditation and 3A standard performance ensure that the test reports have legal effect and can be directly used for grid connection acceptance and product export in both domestic and foreign markets; For large ground power stations in remote northwest areas, the portable large surface area model (weighing only 35kg) can complete component efficiency attenuation detection on-site and provide data within 30 minutes, significantly reducing the cost of detection.
