Most photovoltaic manufacturers focus merely on testing speed and data reading while ignoring the core component of IV testing equipment: the solar simulator light source. As the key to simulating real sunlight, unstable light sources lead to distorted IV curves and inconsistent batch data. Long-term light attenuation and spectral deviation will gradually reduce testing accuracy, bringing hidden risks to module grading and factory data certification. #SolarSimulator
Yoha Solar’s Solar Panel IV Tester/Solar Simulator
The performance of the light source directly determines the credibility of IV testing results. Ordinary low-end simulators suffer from uneven irradiation and severe light decay, which cannot meet the long-term operation demands of PV production lines. In contrast, qualified industrial-grade simulators need to maintain stable spectral performance under continuous high-frequency flashing. Yoha Solar prioritizes light source optimization in its PV testing equipment to solve this common industrial defect. #PVLightSource
All industrial IV testing equipment from Yoha Solar adopts standard xenon lamp light sources, fully complying with IEC 60904-9 international standards. With a spectral coverage of 300nm to 1200nm, the equipment achieves irradiation non-uniformity within ±1% and long-term light instability below 0.5%. Optimized lamp tube layout and internal heat dissipation structure effectively slow down light attenuation, ensuring stable luminous performance during years of continuous batch testing. #YohaSolarTech
