In the wave of the accelerated transformation of global energy structure, the photovoltaic industry is entering a new era of "super large size and ultra high power". When the size of photovoltaic modules exceeds the "mega-screen" era of 3 meters by 5 meters, traditional solar light simulators have fallen into a predicament of "segmented testing, data stitching, and error accumulation" due to limited light spots and insufficient stability. Saifan Photovoltaics, as a national-level high-tech enterprise with over 20 years of experience in the field of photovoltaics, provides a "one-stop solution" for the certification of giant photovoltaic modules and extreme environment material testing with its "giant light spot + 3A-level accuracy" xenon lamp steady-state solar light simulator.
Facing the 3 meters by 5 meters super-large photovoltaic modules, traditional small light spot simulators need to be tested in 15 segments, taking 72 hours, and the total error after data stitching is as high as 8%, causing repeated failures in international certifications. Saifan Photovoltaics' 7IS series ultra-large area xenon lamp steady-state solar light simulator breaks the size barrier with a "3 meters by 5 meters ultra-large area", does not need segmentation, covers the entire plate of the giant module in one go, and the testing time is compressed to 14 hours, with efficiency increased by 5 times, and the certification cost per module is reduced by 65%. Its full indicators of 3A-level accuracy - spectral matching degree A+ level (0.875 - 1.125), light intensity uniformity A level (≤ ± 3%), time stability A level (≤ ± 0.2% / h) - fully meet the IEC 60904-9 and TÜV, UL international certification standards, making "one-time certification" a norm, and helping Chinese photovoltaic products smoothly enter global markets such as Europe and Australia.
Saifan Photovoltaics' xenon lamp steady-state solar light simulator uses imported 1500W ultra-high pressure short arc xenon lamps as the "power core", covering the entire wavelength range of 300nm - 1100nm. Especially, the energy restoration accuracy of the 280 - 400nm ultraviolet wavelength band exceeds 97%, perfectly simulating the full spectrum characteristics of natural sunlight. The light intensity can be continuously adjusted from 100 to 2000W/m², supporting one-click switching of multiple standards such as AM1.5G/AM0/D65, and adapting to the certification requirements of different regions around the world. What's more remarkable is that the equipment adopts a dual circulating water cooling temperature control and gas sealed packaging design, which can operate stably in extreme environments of -40°C to 60°C, providing "military-grade" reliable testing guarantees for special scenarios such as spacecraft solar panels and Mars exploration missions.
Traditional xenon lamp equipment has a light attenuation of over 15% under high temperatures, causing extreme environment tests to be interrupted and the initial investment in research and development to be wasted. Saifan Photovoltaics' xenon lamp steady-state solar light simulator, through intelligent spectral fitting algorithms and closed-loop feedback control systems, has a light intensity fluctuation rate of less than 0.08% for 8 consecutive hours, far exceeding the industry average of 0.3%. In the 1000-hour aging test of spacecraft whole plate materials, the equipment always outputs stably, fully recording the aging laws of the materials, and helping the development of new anti-radiation coatings to extend the lifespan of battery wings from 5 years to 15 years. Its xenon lamp lifespan is up to 1000 hours, supporting rapid replacement (only 15 minutes), and generating an annual output of over 30 million yuan, completely eliminating the hassle of "changing lamps every half a year" and work stoppage.
Saifan Photovoltaics' xenon lamp steady-state solar light simulator is not only a "powerful device", but also the embodiment of "smart light". The equipment is equipped with an intelligent control system, which can precisely control the irradiation intensity, spectral band, and testing mode through a PC software, supporting remote monitoring and data traceability. The modular design also supports customized sizes ranging from 1m by 1m to 5m by 5m, and can flexibly adapt to various scenarios such as laboratories, production lines, and pilot platforms. Whether it is simulating the "AM0 + infrared enhancement" light on the Martian surface or replicating the extreme high temperature and strong light in tropical regions, it can "set once and reproduce precisely". Currently, the Sefan Optoelectronics Xenon Lamp Steady Solar Light Simulator has demonstrated its capabilities in numerous leading photovoltaic enterprises and aerospace research institutions across the country. After a multinational photovoltaic company adopted Sefan's equipment, the certification of its giant components was successfully completed in one go, and the products smoothly entered the European market, generating an annual additional output value of over 500 million yuan. A certain aerospace technology group utilized its extreme environment testing capabilities to successfully solve the problem of aging assessment of aerospace materials. The relevant achievements were applied to the construction of the space station, contributing "light power" to the country's aerospace endeavors.
From "giant component certification" to "aerospace material testing", Sefan Optoelectronics has always been a "light customizationist" providing precise and reliable lighting solutions for the photovoltaic industry and aerospace endeavors. Choosing Sefan's xenon lamp steady solar light simulator is not only choosing a piece of equipment, but also choosing a trustworthy "light partnership" to work together with you in the journey towards the "dual carbon" goals and the "space power nation", accurately assessing the future and moving forward towards the light.
