Light Stability Test And Hot Spot Test System

Product description Specifications Download

      Meets the hot spot test of solar modules specified in the 4.9 clause of the IEC 61215-2016 standard and the light stability test requirements specified in the 4.19 clause of the IEC 61215-2016 standard .

The temperature of the environmental chamber is controlled by forced air-cooling, with over-temperature and low-temperature alarm functions. The surface temperature of modules can be tracked and recorded.

Specially designed metal halide light source long life.

The irradiance of each light source can be controlled separately.

Monitor irradiance, accumulate irradiation, and the test time can be controlled by irradiation.

Include an electronic load (MPPT load) with maximum power point tracking function so that the module can work at the maximum operating point during the work process.

Can record irradiance, irradiation, and module working power. All data can be exported to EXCEL table, which is convenient for data analysis and comparison. Temperature and irradiance data are automatically stored in the hard disk and can be permanently saved. The number of the test sample can be input during recording, and the data file automatically generated when the test ends can be saved.
