Beijing SOFN Optoelectronics has targetedly overcome the technical challenges in large-area detection. Based on the SS-P8000 series, they have upgraded and launched the large-area customized version of the 3A-level pulsed solar light simulator, with the core advantages of "super large size full coverage, 3A-level uniformity across the entire area, and flexible adaptation to irregular scenarios". This has made it the "preferred equipment for all-round precise detection" in fields such as BIPV, vehicle-mounted photovoltaics, aerospace super-large solar sails, and large-scale power station operation and maintenance.
1. Core Technology: Specialized innovation for large-area detection, redefining the standard for super-large size detection
Saifan's large-area pulsed simulator breaks the industry deadlock of "larger size necessarily sacrificing accuracy" by means of three exclusive technological innovations, achieving a perfect balance of "super large area + 3A standard + efficient detection":
Extensive size coverage: From 1.2×1.5m to 3×2m, with no limit on customization
Based on the "modular assembly + adaptive light source array" technology, the irradiation surface size can be flexibly customized, with the maximum support of 3000×2000mm super large area (covering aerospace-grade solar sails), and the minimum suitable for Φ200mm regular components. Without splicing, it can complete integrated detection, completely solving the problem of data breakage in traditional splicing detection. For BIPV irregular components (such as curved walls and irregular roofs), non-rectangular irradiation surfaces can be customized, with edge adaptation error ≤ ±2mm, perfectly matching the diverse design requirements of building-integrated photovoltaics.
All-round 3A uniformity: ±1.2% light intensity deviation, far exceeding industry standards
Innovatively, "honeycomb-shaped uniform light array + multi-light source synchronous calibration algorithm" is adopted, supported by 38 core patent technologies (including 2 exclusive honeycomb-shaped uniform light patents), achieving full irradiation surface light intensity uniformity ≤ ±1.2%, spectral matching coefficient 0.85-1.15, short-term stability ≤ ±0.3%, with all three indicators reaching 3A standards. Even at 1200×1500mm super large size, the spectral energy deviation at the edge and center is still ≤ 0.5%, capable of accurately capturing the local performance differences of large-sized components, and directly connecting to the GB/T 37655 BIPV acceptance specifications and aerospace-grade calibration standards.
Efficient synchronous detection: Ultra-large components 0.3-second speed measurement, improving operation efficiency by 10 times
Continuing the core advantages of the pulsed technology, a single pulse can complete the full parameter collection of ultra-large-sized components' IV curves. For 1200×1500mm components, the detection only takes 0.3 seconds, which is 20 times more efficient than traditional steady-state equipment and 5 times faster than similar large-area equipment. Equipped with "all-round multi-point synchronous collection technology", it can simultaneously monitor the light intensity and electrical performance data of 16 areas, particularly suitable for batch operation and maintenance detection of large-scale photovoltaic power stations (with a daily detection volume of up to 80,000 square meters), significantly reducing the detection costs and time costs in remote areas of power stations.
2. Scene Enabling: Four emerging fields, becoming an indispensable core detection equipment
Saifan's large-area pulsed simulator precisely matches the exclusive needs of super-large size, irregular structures, and batch detection, achieving benchmark applications in four emerging fields:
BIPV projects: Adaptation to irregular shapes + compliance acceptance, accelerating the speed of building-integrated photovoltaics
A leading BIPV enterprise adopted a customized version of 1.8×1.2m equipment to detect 1×2m perovskite irregular components, without splicing, it can complete integrated detection, detection efficiency increased by 3 times, defect identification accuracy rate reached 99.8%, data directly meets the GB/T 37655 acceptance specifications, helping the project pass the grid connection acceptance 2 months earlier, reducing compliance rectification losses by over 3 million yuan. For frameless double-glass modules (such as Longi Sententron 3.0), the equipment can precisely detect the performance degradation of the sensitive areas of the dust accumulation, providing data support for component optimization.
Vehicle-mounted photovoltaic (VIPV): curved surface adaptation + dynamic testing, accelerating the development of solar vehicles
A 2.5×1.8m curved surface adaptation equipment was customized for a certain new energy vehicle manufacturer, successfully simulating the actual installation scenario of the roof photovoltaic components. By adjusting the pulse width (10-1000μs), the transient response characteristics of the vehicle-mounted components under dynamic lighting were captured, helping the R&D team increase the solar vehicle's range by 18%, and the related technical achievements were applied to the new solar vehicle, reducing carbon emissions by over 220kg per vehicle per year.
Aerospace super large solar panels: extreme environment + super large size, ensuring in-orbit performance
A 3000×2000mm super large size equipment was customized for the Aerospace Science and Technology Group, suitable for vacuum / high-temperature low-temperature environments (-50℃~90℃), simulating the AM0 spectrum in space. Under such an ultra-large size, the irradiation stability remained ≤±0.5%, and the transient irradiation calibration of the new-generation space station solar panels was successfully completed, providing key data support for in-orbit power generation performance prediction, breaking the monopoly of similar equipment in the aerospace super large size field.
Large-scale power station operation: batch detection + rapid compliance, reducing operation costs
A large-scale photovoltaic power station in the northwest region used multiple 1.5×1.2m equipment to form a detection matrix, achieving batch rapid detection of the power station components. The daily detection volume of a single equipment reached 12,000㎡, which was 10 times more efficient than traditional manual inspection. The detection data was directly connected to the NBT 11354-2023 quality management regulations, helping the power station PR value increase to over 85%, and increasing annual power generation by over 5 million kWh.
III. Value Upgrade: Benchmark of large-size domestic equipment, reshaping industry service standards
The Saifan large-size pulse simulator, with "technology autonomy + scene deepening + service upgrade", has become the leader of domestic super large-size detection equipment:
