On July 22, 2026, Yoha Solar finished commissioning, quality inspection and shipment of its AM0/AM1.5G steady-state LED solar simulator. Delivered to a professional research laboratory, the equipment provides high-precision, stable and standardized light simulation for PV cell performance testing, module calibration and new material research and development.
Yoha Solar Steady-State LED Solar Simulator
This self-developed flagship water-cooled LED solar simulator supports one-click switching between AM0 and AM1.5G spectra, covering aerospace and terrestrial PV testing scenarios. The AM0 mode features a 300~1700nm spectrum and 1367W/㎡ standard irradiance for space PV device simulation, while the AM1.5G mode covers 300~1200nm with 1000W/㎡ irradiance for civilian PV testing. It achieves Class A rating for AM0 and top A+ grade for AM1.5G, fully complying with international testing standards.
High-precision steady-state testing
Tailored for long-term high-precision steady-state lab testing, the simulator meets Class A industry standards with irradiance non-uniformity and temporal instability both ≤2%. Its 300×300mm effective irradiation area supports simultaneous testing of multi-spec PV samples. Equipped with a water circulation cooling system (superior to traditional air-cooled designs), it enables stable long-duration operation, eliminates temperature-induced spectral drift and irradiance deviation, and adapts to rigorous aging testing and stability calibration experiments.
Steady-state LED light
Featuring a PLC intelligent control system and touch terminal, the device supports 0~99% linear continuous power adjustment and rapid precise calibration with portable irradiance meters. It integrates hierarchical access control, power-off memory, runtime statistics and automatic fault logging, supporting convenient operation and traceable standardized laboratory management. Multiple safety protections including overload, electric leakage, overheating and water-cooling anomaly, plus a physical emergency stop structure, ensure full operational safety.
Touch control terminal
