The industrial quality inspection and authoritative certification tests for ultra-large-sized photovoltaic modules, giant photovoltaic plates, ultra-wideband thin-film laminated devices, and large-area photovoltaic functional materials have long been constrained by industry bottlenecks such as insufficient irradiation area of conventional equipment, large stitching errors, incomplete spectra, and poor long-term stability. Traditional small light spot simulators cannot cover the entire giant sample, and multiple zone splicing tests have high error accumulation, poor data repeatability, and extremely low test efficiency; LED large-area equipment generally lacks ultraviolet bands and cannot support high-order conditions such as ultraviolet aging and full-spectrum energy efficiency calibration; ordinary industrial-level simulators have significant long-term light intensity drift and obvious spectral attenuation, which easily cause component efficiency grading distortion, aging experimental data dispersion, and are difficult to meet the strict standards of large-scale photovoltaic enterprises' mass production quality control, pilot process iteration, and third-party authoritative certification, thereby restricting the industrialization improvement and efficiency enhancement of ultra-large-sized photovoltaic devices.

Deeply specializing in the field of high-end large-scale photovoltaic illumination simulation and precise detection, Saifan Photovoltaic relies on imported short arc xenon lamp full-spectrum replication technology, ultra-large irradiation area compound eye uniform light optical architecture, and the eighth-generation dual-loop dynamic steady-state compensation algorithm, and has launched the ultra-large irradiation area 3A level xenon lamp steady-state solar light simulator. Strictly following the international authoritative standards of IEC 60904-9:2020 and ASTM E927, it achieves full coverage of three 3A top-level indicators of spectral matching, irradiation uniformity, and time stability. With a huge integrated irradiation area, full-band non-destructive solar light replication, industrial-level ten-thousand-hour steady-state, and high-efficiency low-cost sample testing, it overcomes the problem of precise testing of large-sized photovoltaic samples in one-to-one integration. It provides a compliant, efficient, and traceable ultra-large-area steady-state illumination solution for large-scale new energy enterprises' industrial quality inspection, universities' cutting-edge research, high-end pilot process iteration, and authoritative certification testing.
