1.According to the requirements of the contract, the power and level of the monocrystalline silicon cell are accepted, for example, 125 grade A, as long as A1's power is 2.57~2.7, then at this time we must ask whether the power of the solar cell is positive or negative. Use positive tolerances.
2. The color of single-crystal silicon cell: single crystal is sky blue or blue, and the surface color is observed under the condition of daily illumination of 35°. The visual color is uniform, and there is no obvious color difference, water mark or fingerprint.
3, the grid line graphics are clear, complete, no disconnection. (B pieces may have 1 to 2 broken lines, but not on the same grid line)
4, the front grid line clean, no leakage of pulp.
5, aluminum back electrode integrity, no prominent raised "aluminum beads.
6. No visible cracks on the monocrystalline silicon cell are allowed.
7. Monocrystalline silicon cells must have no missing corners or edges.
8. Check the appearance, labeling and quantity of each small package.
9. The appearance and total number of packages for each big box (no less than 2 bags per box, check the above items).
10, manufacturers specifications and pay attention to check the actual delivery parameters.
