INTRODUCING PRO PQ CLASS A
The difference between Class A photovoltaic panels and Class B photovoltaic panels
There’s a lot of confusion between different grade solar cells. Any deviation is often graded as B, however a correct classification is complicated because there are dozens of different solar cell defects that can occur. This post is a first attempt to design a classification (A, B, C, D) of solar cells, and is a summary of a more in. . Grade A cellsare simply without any visible defects, and the electrical data are in spec. The specifications of the cells can be measured with cell testing equipment. The perfect grade A cell. . Grade B cells have visible but tiny defects, and the electrical data are in spec. The following visible defects are common: 1. Slight bendof 2.0mm – 2.5mm 2. Color deviation, Visible yellow area takes more than 1/4 area of total on. . A Grade D solar cell is broken and can not be cut in smaller cells. There’s not much you can do with these.. . A Grade C solar cell has visible defects, and the electrical data are off-spec. All solar cells with defects worse than Grade B can be classified as Grade C. Or A solar cell can be graded as C.

What is a Grade B solar panel?
Grade B solar panels have visual defects but meet performance specifications. These solar panels are less common than grade A solar panels but are typically available from manufacturers upon request. Most manufacturers keep these panels for testing purposes but sell them with warranties like grade A solar panels.
Do grade B solar panels affect performance?
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.
What is a Grade A solar panel?
Understanding the Solar Panel Grades of Cells Grade A solar cells are easily the most sought-after for their premium quality. They are devoid of any chips, cracks, and scratches, which helps them convert solar energy into electricity at their best efficiency.
Do you sell grade B solar panels?
Most manufacturers and distributors only sell grade A and B solar panels, scrapping C solar panels and recycling D solar panels. A’s are typically the most advertised and sold. However, some do sell grade B solar panels upon request.
Do grade B solar panels have warranties?
Some companies also have warranties on their grade B solar panels, the same as their grade A’s, and is a good indication of how confident the manufacturers are in the performance of the grade B solar panels. If you’re nervous about grade B solar panels’ performance, look for a business that sells them with warranties.
What are Grade C and grade D solar panels?
Grade C and Grade D panels occupy a niche in the solar panel spectrum, and their use is relatively rare: Grade C Panels: These panels often have severe cosmetic flaws or are made from cells with visible damage. They are typically unsuitable for standard solar installations.
