What is a Grade A solar panel?

Grade A cells are pretty much perfect cells of highest quality. No visual or technical defects. 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!

Are Grade A solar panels a good investment?

Long-Term Savings: Investing in Grade A panels represents a commitment to a cleaner and more sustainable future, with significant savings on energy bills and reduced maintenance costs. In essence, the quality and reliability of Grade A solar panels make them the preferred choice for most solar energy projects.

Are Grade B solar panels good quality?

Grade B: Slightly lower in quality compared to Grade A, Grade B solar panels still offer reliable performance but may have some minor imperfections or downgraded components. They are suitable for applications where absolute top-tier quality is not essential, such as street lighting or off-grid systems.

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.

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.

Do solar panels have a power rating?

To help determine the real-world performance of a solar panel, manufacturers also provide a power rating under Nominal Operating Cell Temperature (NOCT) conditions. NOCT assumes a cell temperature of 45°C and a lower solar irradiance of 800W/m2 to mimic average operating conditions.
