Double-Side Illumination Solar Simulator

The system is mainly used for Bi-facial module testing, and mainly for testing lab use. It uses 2 light source to simulates the real using environment outdoor. Two light source illuminates the front side and rear side simultaneously to test Bi-facial modules IV properties with high precision. The system has 2 types, modules could be placed vertically or horizontally. Both front light source and rear source are A+A+A+ Class and long pulse duration.

Front / Rear Light Source


  1. Light Irradiance : 100-1200W/㎡
  2. Instability of Irradiance : ≤1%, A+ class
  3. Spectral mismatch: 0.875-1.125,A+ class
  4. Non-Uniformity of Irradiance:≤1%, A+ class
  5. Pulse Duration: 10-200ms
  6. Testing area up to 2.6m*1.6m
