Frequently Asked Questions

400 Watt Solar Panel

How does the Multi Busbar Solar Cell technology enhance the performance of the panel?

Multi-busbar (MBB) refers to a technology used in solar panels to improve their efficiency and reliability. In traditional solar panels, there are usually two or three busbars -- thick conductive strips -- on each solar cell that collect the electric current generated by the cell. In Multi-busbar technology, the number of busbars is increased, often to five or more, which has several benefits:

1. Reduced Resistance: More busbars mean shorter distances for electrons to travel, which reduces the resistance within the solar cell and increases the efficiency of the solar panel.

2. Increased Efficiency: The increased number of busbars allows for better collection of electric current generated by the solar cells, which leads to higher efficiency.

3. Improved Reliability: More busbars also mean that if one busbar fails or gets shaded, the others can still collect the electric current, which improves the reliability of the solar panel.

4. Enhanced Aesthetics: MBB technology can also improve the aesthetics of the solar panel as the busbars are thinner and less visible, leading to a more homogeneous appearance.

5. Better Performance in Shaded Conditions: More busbars can result in better performance under partial shading conditions as they provide alternative pathways for the electric current to flow.

6. Reduced Power Loss: The reduced resistance and better current collection result in less power loss within the solar panel.

7. Reduced Cell Cracking: The thin, flexible busbars put less mechanical stress on the solar cells which can reduce the likelihood of cell cracking.

This technology is part of a broader trend in the solar industry to continually improve the efficiency, reliability, and aesthetics of solar panels to make them more attractive and cost-effective for a wide range of applications.

What's PID resistant, and how does it benefit the system?

Potential Induced Degradation (PID) is a phenomenon that can significantly reduce the efficiency and performance of solar panels over time. It occurs due to a buildup of negative charges within the solar panel, which can create a voltage potential that adversely affects the solar cells.

Being PID resistant means that a solar panel has been designed or treated in a way to reduce or prevent the occurrence of Potential Induced Degradation. Here are the benefits of PID resistance:

1. Maintained Efficiency: By resisting PID, the solar panel maintains its performance levels over time, ensuring that the power output remains consistent.

2. Extended Lifespan: PID resistance can significantly extend the lifespan of solar panels by preventing the degradation that would otherwise occur.

3. Increased Return on Investment (ROI): With maintained efficiency and an extended lifespan, solar panels provide a better return on investment as they continue to generate the expected amount of electricity over a longer period.

4. Reduced Maintenance Costs: PID resistance also means potentially lower maintenance costs, as the panels will require less servicing and are less likely to need early replacement due to degradation.

5. Better Performance in Varied Climates: PID can be exacerbated by high temperatures and humidity, so PID resistance is particularly beneficial in hot and humid climates where solar panels are more prone to this type of degradation.

What makes the Full Black 400 Watt Solar Panel visually appealing?

The full-black design of the panel offers a sleek and modern aesthetic, making it an attractive addition to any residential project. The low reflection surface minimizes glare, which can be hazardous, ensuring safer for drivers passing by.

What's the warranty terms of this 400w solar panel?

The product is covered by a 12-year warranty for manufacturing defects and a 25-year warranty for power output.
