For large-area photovoltaic panels, complete battery modules, and small-to-medium-sized photovoltaic components, there have long been industry pain points such as small light spots in equipment, the need for multiple joint tests, large error accumulation, and low test efficiency. Conventional small-sized pulse simulators cannot cover the entire light exposure area of large-sized samples, and zone detection is prone to data deviations and poor batch consistency. Steady-state large-sized equipment continuously irradiation is prone to cause sample heat rise, resulting in temperature-sensitive battery efficiency drift and thermal damage mismeasurement, and is unable to meet the high-frequency, high-speed, no-heat, and high-precision production detection requirements of the production line, severely restricting the large-scale, standardized, and efficient production quality improvement of large-sized photovoltaic devices.

Deeply specializing in large-area photovoltaic precision detection and pulse light illumination simulation, Saifan Optoelectronics relies on ultra-large area compound eye uniform light optical technology, high-precision pulse xenon light spectrum fitting architecture, and millisecond-level flash stability control algorithm, and has launched a large-area 3A-level pulse solar light simulator. Strictly following the international authoritative standards of IEC 60904-9:2020 and ASTM E927, it achieves triple 3A top-level indicators of spectral matching, irradiation uniformity, and time stability coverage. With an ultra-large uniform irradiation area, instantaneous non-thermal pulse flash, full-area high-precision uniform light, and ultra-fast batch detection, it overcomes the core problems of large-scale photovoltaic sample joint test errors, thermal interference distortion, and low detection efficiency. It provides a compliant and traceable efficient pulse light illumination solution for large-scale photovoltaic enterprises' production grading, pilot process iteration, and large-area sample rapid calibration.
