Learn MoreSolar panels are categorised into grades ranging from A to D, with the A-grade bracket further divided into A+ and A-. Understanding the grade of a solar PV panel is crucial in determining its quality and performance. In this article, we will provide an overview of the various solar panel grades and how to assess them.
Ultimately, it comes down to this: Grade A solar panels have no visual defects and meet performance standards. Grade B solar panels have some visible defects but meet performance standards. Grade C solar panels have visual defects and do not meet performance standards. Grade D solar panels are unusable, and entirely broken.
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.
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.
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.
Modules made with Grade A cells degrade at a slower rate, approximately 0.3 – 0.5% per year. That means that after 10 years, high-quality PV panels would retain approximately 95% of their original capacity! This gradual degradation means they retain higher energy output and maintain their effectiveness for much longer than lower-grade panels.
