Liu, the R&D director of a large building materials group, also paid a heavy price due to the "distortion" of test data: "The BIPV panels we developed have a weather resistance life of 15 years in laboratory tests, but they turned yellow and cracked just 8 years after actual installation, causing 12 projects across the country to have to be reworked and resulting in losses of over 120 million yuan." It was only after the investigation that it was found that the spectrum of the traditional simulator could not match the actual usage scenarios of the building materials at all. Coupled with the poor uniformity of irradiation, the local data could not represent the performance of the entire board at all, which was equivalent to making a mistake from the source.
In response to the special demands of the building materials industry, Saifan's customized solutions have precisely broken through the deadlock. The device is equipped with a dedicated spectral library for building materials, specifically optimizing the energy proportion of the 300-400nm ultraviolet band - this band is precisely the key factor affecting the weather resistance of building materials. As a result, the spectral matching degree has soared to 98.5%, and the consistency with the actual outdoor lighting conditions exceeds 96%. Combined with the distributed multi-point uniform light technology, the irradiation uniformity is ≤±2%, the temperature difference of the entire board material is ≤±0.8℃, and the deviation of the test data of the same batch is ≤1%. It can accurately predict the actual service life of the material and avoid quality risks from the source.
"Now, the actual service life of BIPV panels deviates from the test value by no more than one year, and there have been no more rework issues!" " Engineer Liu introduced that this device also supports extreme weather resistance tests ranging from 5,000 to 20,000 hours. Combined with rain and sandstorm simulation modules, it can fully reproduce the complex outdoor environment, and the testing efficiency is increased by three times. The energy consumption advantage surprised him even more: "Previously, the annual electricity cost for six traditional devices was 500,000 yuan and the maintenance cost was 300,000 yuan. Now, the annual electricity cost for one Saifan Steady-state device is only 80,000 yuan and the maintenance cost is 40,000 yuan. It also saves 80% of the laboratory space and the equipment investment can be recovered in three years."
