Technical FAQs 4

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 are solar panels graded?

Like elementary school, solar panels are graded on several factors, mainly visual and performance flaws. While this grading system follows similar logic, different manufacturers and distributors can have other criteria for their grading systems.

What are Grade A solar cells?

Grade A solar cells are the elements of the highest quality. They lack chips, cracks, and scratches, which lead to a decrease in the efficiency of conversion of solar energy into electricity. They have an ideal appearance, uniformity of crystals, colors, etc.

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.
