Today, as the photovoltaic industry moves towards super-large sizes and high-precision certification, traditional testing equipment is facing severe challenges - the certification of 3m×5m giant photovoltaic modules requires segmented testing, with a splicing error exceeding 8%, which has repeatedly hindered international certification. Under extremely high-temperature conditions, the material aging test is interrupted due to the attenuation of light intensity. Under the demand for strong ultraviolet irradiation, the energy of traditional equipment is insufficient, and the efficiency deviation of the photocatalytic pilot is significant. These pain points have plunged countless enterprises and research institutions into the predicament of "data failure and project delay".
Saifan Optoelectronics has been deeply engaged in optoelectronic technology for 20 years. It has broken through with innovation and launched a large-format 3A-level xenon lamp steady-state solar simulator. With the three core advantages of "ultra-wide coverage area + full compliance with IEC 60904-9 3A-level indicators + xenon lamp steady-state strong core", it perfectly meets the strict testing requirements in large areas, strong irradiation and extreme environments. Today, this "Light beast" has served over 230 high-end customers worldwide, increasing the certification efficiency of giant photovoltaic modules by five times, achieving a 100% pass rate in extreme environment material tests, and having a parallelism of over 96% in strong ultraviolet scientific research experiments. It has become the "hardcore choice" for large-scale and strict light tests.
1. 3m×5m ultra-large format, 3A-level precision, passed international certification in one go
A multinational photovoltaic enterprise was once at a loss over the certification of 3m×5m super-large modules: The traditional small spot simulator needed to be tested in 15 sections, which took 3 days, and the total error after assembly reached 8%. When it was sent to TUV Rheinland for certification, it was directly rejected, and the plan to enter the European market was postponed by 6 months.
The Saifan large-format simulator ends the pain point with a 3m×5m ultra-wide format - no need for segmentation, it can cover the entire board of giant components at one time. The testing time is compressed from 72 hours to 14 hours, the efficiency is increased by 5 times, and the certification cost of a single component is reduced by 65%. More importantly, all indicators meet the 3A-level standards: spectral matching degree A+ level (0.875-1.125), light intensity uniformity A level (≤±3%), and time stability A level (≤±0.2%/h), fully complying with international certification standards such as IEC 60904-9, TUV, and UL.
The strong core advantages of xenon lamps are fully demonstrated: It adopts imported 1500W ultra-high pressure short-arc xenon lamps, with continuous coverage of the entire 300nm to 1100nm wavelength band. The energy restoration accuracy in the 280-400nm ultraviolet band exceeds 97%, far superior to LED devices, perfectly simulating the full-spectrum characteristics of natural sunlight. The light intensity of the equipment can be continuously adjusted from 100 to 2000W/m², and it supports one-click switching of multiple standard spectra such as AM1.5G/AM0/D65, meeting the certification requirements of different regions around the world.
Ii. Extreme Environment Testing: From "Data Failure" to "100% Pass"
In scenarios such as aerospace material testing and strong ultraviolet research, traditional equipment leads to data failure and project delays due to insufficient area, poor anti-fabrication performance, and incomplete full-spectrum coverage.
Saifan Simulator meets challenges with military-grade performance
Dual circulation water-cooled temperature control: In an extremely cold environment of -40℃, the spectral output deviation does not exceed 0.5%, ensuring accurate and reliable in-orbit life assessment of spacecraft battery wings.
Xenon lamp steady-state strong core: The light attenuation is less than 3% after continuous operation for 1000 hours, and it supports quick replacement (lamp replacement only takes 15 minutes), ensuring the continuity of the test.
Full-spectrum coverage: The spectrum from 350nm to 1100nm is precisely restored, with an energy restoration accuracy of over 98% in the near-infrared region, meeting the "non-destructive inspection" requirements of new types of batteries such as perovskite and organic thin films.
Iii. Cost Reduction and Efficiency Enhancement: From "High Operation and Maintenance Costs" to "Recoup Investment within Two Years"
The annual electricity cost of a traditional xenon lamp simulator is 400,000 yuan, and the loss due to lamp replacement and line shutdown exceeds 1.2 million yuan. However, the Saifan equipment saves 240,000 yuan in electricity costs annually, and the xenon lamp has a lifespan of 1,000 hours, generating an output value of over 30 million yuan in more than a year.
Saifan large format simulators reshape the cost structure with "long-term economy"
Low-power design: The overall power consumption of the machine is only 60% of that of traditional equipment, and a 1GW production line can save 200,000 yuan in electricity fees annually.
Automated testing: It can screen 60 batteries per minute, with the A-grade product rate increasing from 88% to 93%, reducing defective product losses by 12 million yuan annually.
Rapid return on investment: Calculated based on a 10-year service life of the equipment, the cumulative cost savings exceed 2.2 million yuan, which is equivalent to earning the profits of two additional small-scale test production lines.
Iv. Global Recognition: From "Certification Rejection" to "Data Passage"
The Saifan simulator has passed international certifications such as IEC 60904-9 and JIS C 8912. The test data are recognized by German TUV and American UL. When the products are exported to the European Union and North America, there is no need for secondary testing, and the certification cycle is shortened by 60%.
Customer Witness
A leading photovoltaic enterprise: "Now, the sample certification has been passed in one go. International testing institutions all recognize the data of Saifan's xenon lamp equipment, and the products have smoothly entered the European and Australian markets."
Aerospace testing agency: "The spectral output deviation of the equipment does not exceed 0.5%, reducing the in-orbit life assessment error from 3 years to 0.5 years."
The large-format 3A-level xenon lamp steady-state solar simulator of Saifan Optoelectronics redefines the photovoltaic testing standards with "ultra-wide format, 3A precision, and xenon lamp strong core", making every beam of "artificial sunlight" a driving force for innovation. Whether it is the certification of giant components, extreme environment testing, or the demand for cost reduction and efficiency improvement, Saifan has always used technology as a sharp tool to cut through the fog of the industry and illuminate the future path of the photovoltaic industry.
