How to identify the grade of photovoltaic panels

Grade B solar panels have some visual defects that do not affect performance. Grade B naturally falls below grade A in this grading system. So how does Grade B stack up against the other grades? Grade A solar panels are entirely free of defects. Grade B has some visual flaws but still meets performance standards. Grade C.
