FAQs 6
What is the grading system for solar panels?
The grading system goes A for the best, B for visually defective panels but meet performance benchmarks, C for visually and performatively defective solar panels, and D for broken solar panels. Most manufacturers and distributors only sell grade A and B solar panels, scrapping C solar panels and recycling D solar panels.
Are Grade A solar panels a good choice?
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.
How many grades of solar panels are there?
There are four grades of solar panels, but only three of them are usable. Some manufacturers may expand upon this with pluses and minuses to show how individual solar panels rank, but this is rare.
How are solar panels rated?
Solar panels receive their ratings under specific testing conditions known as “Standard Testing Conditions” or “STCs”. These conditions serve as the industry standard for evaluating solar panels, making it easier to compare panels accurately. STCs replicate ideal operating conditions, including: And a “Solar Cell Temperature” of 25°C.
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.
Are Grade C solar panels worth it?
Grade C solar panels have visual and performance defects, causing them to fall far behind in desirability. Grade C solar panels usually sold overseas at far lower prices in third-world countries. Buying these solar panels is not worth it as they break down much faster and don’t make nearly as much power as grade As and Bs.
