A-Grade Solar Panels: Premium Performance, Premium Price

A-grade solar panels represent the pinnacle of quality and performance in the solar industry. Crafted from flawless solar cells and engineered to deliver optimal efficiency and longevity, A-grade panels offer unmatched reliability. While they come with a higher price tag compared to other grades, their superior performance and extensive warranties make them an excellent investment for those prioritizing top-tier quality.

B-Grade Solar Panels: Value without Compromise

B-grade solar panels offer a balance of affordability and functionality, making them an attractive option for budget-conscious consumers. While they may have minor imperfections that do not affect performance, B-grade panels still deliver reliable energy production at a fraction of the cost of A-grade panels. This makes them a great choice for homeowners and businesses looking to maximize their return on investment without sacrificing essential functionality.

Why Choose B-Grade Panels?

1. Cost Efficiency: B-grade panels provide significant cost savings compared to A-grade options, making solar energy more accessible to a broader range of consumers.

2. Reliable Performance: Despite minor cosmetic imperfections, B-grade panels are structurally sound and capable of generating power just as efficiently as A-grade panels, ensuring reliable performance over the long term.

3. Suitable for Various Applications: Whether for residential or commercial use, B-grade panels offer a cost-effective solution for those seeking to harness the benefits of solar energy without breaking the bank.

4. Warranty Coverage: While warranties for B-grade panels may be slightly less comprehensive than those for A-grade panels, reputable companies still offer assurances of product quality and performance, providing consumers with peace of mind. All of our B-grade modules come with a 3-year company warranty.

In conclusion, while A-grade solar panels offer unparalleled performance and longevity, B-grade panels present a compelling cost-efficient alternative without compromising essential functionality. By understanding the differences between these grades and considering their specific needs and budgetary constraints, consumers can make an informed choice that aligns with their goals for sustainable energy consumption. Whether aiming for premium performance or cost-effective solutions, there's a solar panel grade to suit every preference and budget.

The grade of solar panels can be divided into Grade A, Grade B, Grade C and Grade D, while grade A solar panels can be divided into Grade A + and grade A &#; . The cost gap between different grades of solar panels is also very large. What kind of solar panel is called class A and what kind of solar panel is called class D?

Class A solar panels: use class A solar cells, which are the highest quality solar cells;

Grade B solar panel: Grade B solar panel is slightly lower than Grade A

Grade C solar panels: Grade C solar panels are seriously poor in appearance and lack of corners. They are only suitable for making small solar panels.

Grade D solar panels: Grade D solar panels use broken solar cells, which are supplied to customers with special needs or special treatment.

How should we judge?

Judge the grade of solar panel from the following points:

1. Look at the surface

Carefully check the tempered glass surface. The glass surface of solar panels with poor quality is relatively rough, and the residual silica gel on the surface will reduce the power generation efficiency of solar panels.

2. Look at the solar cells

Check whether the solar cell has broken edges and cracks. Poor quality solar panels are spliced with broken solar cells, which has great potential risks and will affect the safe use of the whole solar panel.

3. Look at the back

Look at the quality of the back lamination. If there are irregularities after lamination, such as bubbles and folds, it is regarded as a product of relatively poor quality.

4. Look at the border

Whether it is straight. The poor quality solar panel adopts the method of adding frame manually, which is not firm enough.

5. Look at silica gel

Check whether the silica gel around the back is evenly distributed and tightly penetrated into the gap between the back plate and the frame.

6. Look at welding

Carefully observe the string welding of solar cells for missing welding. At the same time, we should also see whether the arrangement of solar cells is regular.

7. Look at the junction box

Finally, check whether the junction box is firm, whether the junction box cover can be firmly and tightly attached to the junction box, and whether the outgoing wire lock can rotate freely and tighten.
