As a leading domestic enterprise in optical simulation technology, Saifan Optoelectronics' 3A-level steady-state solar simulators have served over 320 high-end customers worldwide, covering core fields such as photovoltaics, aerospace, automobiles, and scientific research. The following selected typical cases demonstrate how equipment can help customers break through technical bottlenecks with the three major advantages of "long-term stability, precise control, and cost savings"
Case one: Photovoltaic Module 10,000-hour Certification - 1 unit equivalent to 3 units, zero rework saves 4 million
Customer background : A leading domestic photovoltaic enterprise needs to obtain the highest-level certification from TUV Rheinland to enter the European market.
challenge : After 5,000 hours of operation of the traditional simulator, the light intensity drift exceeded 7%, the spectral matching degree dropped to grade B, and the certification data was rejected. The splicing error of the 210mm super-large component during the segmented test is serious.
Solution : The Saifan 3A-level steady-state simulator is adopted, equipped with the 8th generation intelligent steady-state drive system (current stability ±0.005%) and military-grade dual-circulation water cooling (temperature control accuracy ±0.05℃). After continuous operation for 10,000 hours, the light intensity drift is ≤±1.2%, and the spectral matching degree is ≥97.5%.
results :
Pass the 10,000-hour certification in one go, saving 4 million yuan in rework costs.
The 3.2m×5.0m ultra-large format uniform light system enables seamless testing of full-size components, with 100% data passing TUV audits.
The intelligent switching between xenon lamps and LED dual light sources has reduced the annual lamp replacement cost from 200,000 yuan to 30,000 yuan, lowering energy consumption by 60% and saving 450,000 yuan in electricity fees annually.
customer review : "The stability of the equipment is comparable to the top international level, helping us enter the European market six months ahead of schedule and generating an additional annual revenue of over 800 million yuan."
Case Two: Spacecraft Weathering Test - Replicating "Space Light" in 7 days to Escort deep Space exploration
Customer background : A certain team from China aerospace needs to verify the on-orbit performance of the solar panels of the Mars rover.
challenge : Traditional simulators cannot accurately reproduce the Mars spectrum (AM0 spectrum + infrared enhancement), and the cycle for customizing imported equipment is as long as three months.
Solution : Saifan customizes spectral modules to precisely simulate the Martian lighting environment. The light intensity stability of the equipment is ≤±1.2% in extreme environments ranging from -40℃ to 60℃.
results :
Complete ground verification within 7 days to ensure the in-orbit reliability of the solar panels of the Mars rover.
The military-grade aluminum alloy body and dual circulation water cooling system ensure that the spectral output deviation is ≤0.5%.
customer review : "The response speed and accuracy of the equipment far exceeded expectations, providing crucial support for the success of the task."
Case Three: Weather resistance test of Automotive Coatings - Zero deviation verification, avoiding 80 million recall losses
Customer background : An international automotive brand needs to verify the weather resistance of the exterior coating for its mass-produced models.
challenge : The inaccurate spectrum of traditional simulators led to color differences in mass-produced models, forcing them to recall and causing losses of over 80 million.
Solution : The Saifan 3A-level simulator reproduces the full spectrum of natural light with an accuracy of spectral matching error of ≤5% and irradiation uniformity fluctuation of ≤2%.
results :
Zero deviation in product verification, avoiding recall risks caused by color differences.
The intelligent calibration system automatically calibrates every 100 hours without the need for manual supervision, saving calibration engineers an annual salary of 300,000 yuan.
Youdaoplaceholder0 customer review : "The reliability of the data gives us full confidence in mass production."
Case four: Perovskite material research and development - Efficiency increased by 42%, facilitating SCI paper publication
Customer background : A research team from Qingdao University of Science and technology, specializing in photocatalytic hydrogen production from perovskite solar cells.
challenge : Fluctuations in natural light cause the experimental data to scatter, hindering the progress of research and development.
Solution : The Saifan LED solar simulator achieves full-band A+ level spectral matching from 350 to 1100nm and supports 1% precision adjustment from ultraviolet to visible to near-infrared.
results :
The hydrogen production efficiency has been increased by 42%, and over 20 papers have been published in SCI journals.
The device is ready to use upon startup. After running for 10,000 hours, the light attenuation is less than 3%, ensuring data consistency.
customer review : "A stable lighting environment significantly enhances research efficiency."
Case Five: Agricultural lighting Scheme - Strawberry sweetness increased by 3 degrees, Yield per mu increased by over 10,000 yuan
Customer background : Strawberry grower in yunnan, in need of optimizing the planting environment to improve quality.
challenge : Insufficient natural light leads to low sweetness of strawberries, and the purchase price has been halved.
solution : Saifan's customized lighting solution precisely regulates the spectral band to simulate the optimal growth light environment.
results :
The sweetness of strawberries has been raised from 8 degrees to 11 degrees, and the yield per mu has increased by 10%.
The annual income per mu has increased by over 10,000 yuan, achieving "technology assisting agriculture".
customer review : "The lighting solution has made our strawberries highly sought-after in the market."
