Key takeaways:
Delicacy Laser's mobile IV tester enables on-site photovoltaic module characterization
The AM0 portfolio includes xenon lamp and steady-state LED solar simulators
The company’s simulators support silicon, perovskite, and space photovoltaic applications
China-based characterization equipment provider Delicacy Laser Optoelectronics highlighted its mobile solar simulator and AM0 spectrum solar simulator at SNEC 2026.
Designed for on-site PV module inspection, the mobile/vehicle-mounted IV testing system uses a class A+ pulsed LED lamp as the light source covering the 350-1,100 nm spectral range. It supports irradiance from 200 W/m² to 1,200 W/m², with a measurement cycle time of 5-15 s. The tool can accommodate module sizes up to 2,600 × 1,400 mm. The tool also offers an optional electroluminescence (EL) imaging along with a Hipot test.
As part of its AM0 spectrum simulators, Delicacy offers pulsed xenon lamp-based light sources to test PV modules in an outer-space environment. At each 1 ms step, the lamp's pulse duration ranges from 10 to 100 ms. The xenon lamp covers wavelengths of 300 nm to 1,800 nm and is intended for multi-junction gallium arsenide (GaAs) modules and crystalline silicon modules. The light source is classified in class AAA and offers an irradiance intensity of 1,367 W/m². For measurement, the default area of illumination is 3,000 x 2,000 mm, with a custom adjustment based on the requirement. Delicacy states that, in addition to IV, the tool supports MPPT, dynamic, and hysteresis measurements. The tool is intended to support characterization of multi-junction GaAs cell technologies, which are commonly used in space PV.
The company also offers a steady-state LED AM0 simulator for single-junction perovskite applications. This simulator has an adjustable irradiance of 0.1-1.2 sun and a spectral range between 350 nm and 1,100 nm. The LED light source has a lifetime exceeding 20,000 h, with a standard illumination area of 2,600 × 1,400 mm. It incorporates irradiance, temperature, and spectral mismatch correction functions. Additionally, a steady-state, high-collimation, large-area xenon lamp tester is available as part of the company’s AM0 simulator offerings. The lamp lifetime in this scenario is over 1,000 h with a light intensity of 0.5-1 sun. The standard illumination area, module dimensions, and testing functions are similar to those of its steady-state LED counterpart.
