Grade A solar cells are the elements of the highest quality. They lack chips, cracks, and scratches, which lead to a decrease in the efficiency of conversion of solar energy into electricity. They have an ideal appearance, uniformity of crystals, colors, etc.
Such modules usually have only a positive tolerance (i.e. the capacity of the modules is always higher than the passport one) and lower temperature coefficients. Grade B solar cells have visual defects and have a lower filling factor of the CVC characteristic: 0.4-0.7. Their price is usually a bit lower than that of the elements of Grade A.
