Beside the high-efficiency photovoltaic module production line of Longi Green Energy, the 7IS0503A-LED solar simulator of Saifan Optoelectronics is calibrating the power of each photovoltaic panel before leaving the factory with a time stability of ±2%. This precise and stable light is helping enterprises achieve an annual production capacity increase of 5GW. As a leading domestic provider of 3A-level LED solar simulation solutions, Saifan Optoelectronics is reshaping the efficiency and accuracy benchmarks of industrial light testing with its technological strength.
1. Production-level precision: Full-process guarantee from raw material inspection to finished product quality inspection
The industrial-grade advantage of Saifan simulators lies in their strict adherence to production standards:
3A-level spectral matching: Covering the wavelength range of 400-1100nm, the spectral matching degree reaches A + level (0.875-1.125), meeting international standards such as IEC 60904-9-2020, ensuring the consistency of performance of photovoltaic products under different lighting conditions. In the research and development of monocrystalline silicon cells, JinkoSolar has increased the cell conversion efficiency to 24.5% through spectral optimization of the Saifan simulator, reaching the leading level in the industry.
Spot uniformity and stability: By using double compound eye lenses and microprism array technology, the spatial non-uniformity within A Φ70mm spot is achieved to be less than ±1% (Class A standard). It is equipped with built-in light intensity feedback and constant current source, and the long-term irradiation instability is less than 0.7%, providing a reliable test light source for the mass production of photovoltaic modules. In the mass production of components, Tongwei Solar has increased the product yield rate to over 98% by leveraging the stability of the Saifan simulator.
Fast response and lifespan advantages: The response time of the LED light source is less than 1ms, meeting the requirements of rapid switching tests. With an ultra-long lifespan of 100,000 hours, it is five times longer than that of traditional xenon lamps, significantly reducing equipment maintenance costs. In the construction of photovoltaic power stations, Orient Sunlight uses Saifan simulators to conduct on-site performance tests of photovoltaic panels to ensure the stable operation of the project.
Ii. Industrial Application: "Light Empowerment" in the Photovoltaic Industry Chain
1. Raw materials and battery cell production: Dual improvement in efficiency and quality
On the heterojunction battery production line of Aikang Technology, the spectral control function of Saifan simulators has helped the enterprise optimize the amorphous silicon thin film deposition process, enabling the battery cell conversion efficiency to exceed 25%. Meanwhile, the simulator supports rapid IV testing, reducing the testing time for a single battery cell to within 5 seconds and increasing production efficiency by more than 30%.
2. Photovoltaic module manufacturing: Standardization and reliability Assurance
In Trina Solar's module packaging workshop, Saifan simulators are used for the light-induced decay (LID) testing of modules. By simulating 1000 hours of outdoor light, accurately predict the performance degradation of components within a 25-year service life to ensure product reliability. The consistency of its test data helps enterprises establish industry-leading component performance databases.
3. Photovoltaic power station operation and Maintenance: A powerful tool for on-site detection and fault diagnosis
In the large-scale photovoltaic power stations of State Power Investment Corporation, Saifan portable LED solar simulators are used for on-site performance testing of photovoltaic panels. By comparing the IV curves of photovoltaic panels in different regions, the fault points can be quickly located, reducing the fault diagnosis time by more than 50% and ensuring the power generation efficiency of the power station.
Iii. Industrial Services: Building a "production-level" optical testing system
Saifan Optoelectronics has launched the "Optical Intelligence Service Platform" for industrial customers:
Customized production line solution: Customized an automated testing production line for Canadian Solar, integrating multiple 7IS0503A-LED simulators, achieving efficient testing of 500 solar cells per hour, with a 200% increase in production capacity.
