Technical FAQs 4

Should you buy a Grade C solar panel?

These are typically panels with visible defects, major cell damage, or inconsistent performance. If you come across heavily discounted solar panels with no clear certifications, there’s a strong chance you’re looking at Grade C. These should be avoided — especially for long-term infrastructure projects.

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.

What is a Grade C solar panel?

Grade C panels are considered non-standard, rejected, or recycled modules. These are typically panels with visible defects, major cell damage, or inconsistent performance. If you come across heavily discounted solar panels with no clear certifications, there’s a strong chance you’re looking at Grade C.

Are Grade C solar panels bad?

Grade C solar panels fall behind in both looks and performance. They look shabby, perform shabbily, and break down sooner than grade As and Bs. Manufacturers sell grade C solar panels at a loss to third-world countries to avoid the hazardous material fee.
