Is A grade better than the B grade when we buy the poly solar cells.
We did a test based on 10 poly solar cells we bought in the market, and it turns our 5 of the poly solar cells claimed to be A grade product is just the same as the B grade.
I think the A grade is better than B grade, but just not sure how better it can be compared to the others.
Poly Solar Cells B Grade might not sound very competitive to the purchasing managers who are purchasing the poly solar cells in the market, but that’s what I need.
The poly solar cell with A grade means the sustainabilty and quality of the poly solar cells are better than the others.
The quality of the poly solar cell is differentiated by grade, therefore, A grade is better than B grade.
