About the LumiProbe

The LumiProbeTM series includes our new innovative, compact I-V hardware module for LED solar simulators that meets IEC 60904-1, IEC 60904-5, and ASTM E948-16 for standardized test methods of electrical performance of different types of photovoltaic cells & solar panels. The measured voltage ranges from 0-20VDC with maximum test-point power of 40W. The voltage step of 400µV and low measurement error of less than 0.1% makes it a highly accurate instrument for complete PV cell characterization.

While use with our proprietary LumiSun Control Center optimizes LumiProbe’s capabilities, we offer full compatibility with LabVIEW for ease of integration with third-party devices and the same plug and play experience. All the communication is streamlined via a USB-C cable, ensuring reliable data transfer.

LumiProbe offers comprehensive measurement and analysis capabilities for photovoltaic (PV) cells and solar panels, enabling in-depth performance assessments. When integrated with a compatible solar simulator, like the LumiSun-50, LumiProbe provides spectral responsivity across a wide wavelength range of 350nm to 1250nm at varying illumination intensities. Additionally, temperature tracking and control are present to study the performance of different types of solar panels under varying real-world conditions.

Users can control I-V point density and customize the sweep grid to define where the data are collected on the curve. A hybrid voltage-current sweep approach enhances precision at critical regions. Front-edge indicator LED strip provides real-time system status feedback.
