The perfect grade A cell may still have a slight bend of tiny color deviation is permitted. Below a grade A solar cell. Due to the light the color seems to deviate, but in fact, this is a flawless solar cell:.

The appearance of class A solar cell must meet the following standards: no edge collapse, angle collapse, notch, virtual printing, slurry leakage, color spot, watermark, fingerprint, oil stain, scratch, crack, oxidation, yellowing and other defects; No obvious color difference;.

Ultimately, it comes down to this: Grade A solar panels have no visual defects and meet performance standards. Grade B solar panels have some visible defects but meet performance standards. Grade C solar panels have visual defects and do not meet performance standards. Grade D solar panels are unusable, and entirely broken.

CCD refers to panels suffering from deviating and differing cell colors within a given panel as well as diverging cell colors between two panels. The major reason for CCDs lies in the selection of non-coherently coloured cells during the manufacturing process as well as selection of low grade cells that have even deviating colouring within the .
