The authoritative calibration and reliability aging tests of large-sized photovoltaic panels, wide-breadth film components, stacked photovoltaic devices, and large-area photovoltaic materials always face core pain points such as spectral deficiency, insufficient uniformity of the area domain, large stitching errors, and weak long-term stability. Conventional LED large-area simulators have a spectral deficiency in the ultraviolet band and cannot be adapted for ultraviolet aging and full-spectrum energy efficiency verification scenarios; traditional small-area xenon lamp equipment requires multiple zone splicing tests, with high systematic errors and poor data repeatability, making it difficult to achieve integrated and precise detection of the entire sample; ordinary industrial simulators have significant long-term light intensity drift and insufficient spectral stability, which easily cause component efficiency grading deviations and discrete aging experiment data, unable to meet the strict testing standards of high-end photovoltaic pilot production, mass production quality control, and third-party authoritative certification, restricting the high-quality upgrade of large-area photovoltaic devices.

Deeply specializing in the field of high-end precision daylight simulation and photovoltaic testing, Saifan Optoelectronics relies on imported short-circuit xenon lamp full-spectrum replication technology, ultra-large area compound eye uniform light optical architecture, and the eighth-generation dual-loop dynamic steady-state compensation algorithm, and has launched a large-area 3A-class xenon lamp steady-state solar light simulator.
