                                          Sample Measurement Result
    After measurement, we can see the yellowness value of the solar backplane films and yellowness difference value directly on screen. With the value, we can evaluate the products quality to meet customer’s high quality requirement and ensure that solar cells absorb solar energy, and improve the power output of solar modules.
