In 2025, China's photovoltaic industry maintained a high growth trend, with new installed capacity exceeding 317 million kilowatts. High-efficiency technologies such as perovskite and TOPCon are accelerating mass production, and "precise detection to reduce costs" has become a consensus across the entire industry. According to the IEC 60904-9 international standard, the 3A level solar simulator, as the "benchmark equipment" for photovoltaic testing, must meet all three core indicators: spectral matching (0.75-1.25), irradiation uniformity (≤2%), and irradiation stability (≤±0.5%/h). These three indicators are essential to ensure the authenticity and controllability of battery efficiency data and component quality.
However, the industry generally faces the dilemma of "high-end equipment being expensive and ordinary equipment lacking precision": imported 3A level simulators cost over one million yuan, making them unaffordable for small and medium-sized enterprises; ordinary equipment suffers from light intensity drift and poor uniformity, resulting in detection data deviations exceeding 3%, affecting product certification and market competitiveness. Beijing Saifan Optoelectronics, with 22 years of experience in photovoltaic testing, directly addresses the industry's pain points and launches the SS-6000 series 3A level steady-state solar simulator - fully compliant with the IEC 60904-9 3A standard. With its core advantages of "precise and reliable, high cost-effectiveness, and flexible adaptation", it becomes the preferred solution for photovoltaic enterprises' mass production testing, research and verification, and third-party certification, making 3A level detection technology accessible to more industry participants.
1. Hard-core implementation of 3A standard: All three core indicators fully meet the requirements, data is real and traceable
Saifan's SS-6000 series takes "standard as the measure, technology as the foundation", converting 3A-level performance into quantifiable practical value, solving the industry's "pseudo 3A" problem:
Precise spectral matching reproduction: 0.75-1.25A level standard
Using imported 2500W short arc xenon lamps and AM1.5G dedicated filters to precisely cover the core wavelength bands of 300-1100nm of solar spectrum, especially optimizing the spectral matching degree for perovskite and TOPCon high-efficiency batteries in the visible light region, the measured spectral matching coefficient is 0.82-1.18, fully meeting the IEC 60904-9 A level requirements. Calibrated by the national photovoltaic metrology station, the conversion efficiency measurement deviation is ≤±1%, and the data can be directly used for international certifications such as TÜV and UL, avoiding the problem of falsely high efficiency due to spectral mismatch.
Uniformity + stability dual excellence: ≤2% uniformity, ≤±0.5%/h stability
Innovatively adopting "dual integral sphere uniform light technology", achieving uniformity ≤1.8% (central area ≤1.5%) within the irradiation surface Φ150mm, far exceeding the 3A standard's ≤2% requirement, ensuring consistent detection data at the edge and center of the component; equipped with a closed-loop light control system and intelligent air cooling, with an irradiation stability ≤±0.4%/h for continuous operation for 72 hours, short-term stability (STI) ≤0.3%, solving the pain points of traditional equipment's "startup drift, long-term degradation", with core components (xenon lamp, optical filter) having a lifespan of over 6000 hours and maintenance costs reduced by 40%.
Easy operation + data traceability: Full process automation, compliance guaranteed
Deeply integrated with Saifan SpectraSmart simplified version analysis software, no need for professional programming, one-click completion of "light intensity calibration - IV scanning - data export". Built-in 10+ industry standard templates including IEC 61215 and IEC 61730, it automatically calculates 12 core parameters such as short-circuit current, conversion efficiency, and fill factor. The data format is compatible with mainstream formats like CSV and TXT, and can be directly connected to LIMS laboratory management systems to meet product quality traceability and compliance requirements. It supports single-time automatic calibration of standard components, with the light intensity accuracy reaching 1366 ± 20 W/m² after calibration, and the operational efficiency increasing by 30%.
II. Scenario Adaptation: From production lines to laboratories, covering the core needs of the entire industrial chain
Relying on 3A standard performance and high cost-effectiveness advantages, the SSV-6000 series has deeply served the entire photovoltaic industry chain and become the "precise detection partner" for different scenarios:
Component production line inspection: Cost reduction and efficiency improvement, with the pass rate reaching 99.9%
A photovoltaic component factory in Zhejiang used the SSV-6000 to build an automated inspection line, conducting 100% online IV testing on N-type TOPCon components. Through the "uniform illumination + rapid scanning" technology, the single-component inspection time was reduced to 6 minutes, and the daily inspection volume increased by 50%; the equipment could automatically identify defects such as hidden cracks and broken grids, reducing the factory's defective product rate from 0.3% to 0.03%, and saving over 5 million yuan annually. For the production capacity needs of small and medium-sized enterprises, it supports flexible configuration of single or double workstations, with an investment return period of only 12-18 months.
High-efficiency battery research: Reliable data, accelerating technology iteration
Research institutions such as Shanghai Jiao Tong University and South China University of Technology used the SSV-6000 to conduct stability research on perovskite batteries. Its precise light intensity control and low fluctuation characteristics successfully captured the efficiency attenuation curve of the batteries under continuous illumination, with experimental data having a repeatability of 98%, helping the research team shorten the material optimization cycle by 30%. It supports adjustable light intensity ranging from 0.2 to 1.1 S0, allowing for simulation of different regional sunlight intensities, meeting diverse experimental needs.
Third-party certification + power station operation: Authoritative compliance, detection无忧
Many third-party testing institutions have selected the SSV-6000 as the benchmark equipment for certification， with its 3A standard performance and CNAS accreditation ensuring that the test reports have legal effect； in the photovoltaic power station operation scenario， the portable model (weighing only 12kg) can conduct on-site detection of component efficiency attenuation， without the need for a darkroom， completing a single-component inspection within 30 minutes， providing precise data support for power station asset assessment.
