182mm 550W monocrystalline solar panel is a very popular product of sunket.
About 550W mono solar panel
550W mono solar panel uses the new 182mm 10/11 busbar high efficiency mono cells. Compared with the previous 158mm mono solar cells solar panel, 182mm solar panel increases the wafer size, optimizes the layout profoundly and decreases the invalid power generation area. it has higher performance. 182mm 550W monocrystalline solar panel component size is 2278×1134×35mm, It uses a half-cell process to divide the battery into two parts, a total of 144 half-cells are required for a 550W solar panel.
Why use the half cell technology?
- The half-cut cell design can decrease the power loss by the shadow effectively.
- The optimized circuit design can realizes the maximum power output
- Assures the reliability of solar panels.
Through experimental comparison, the half-cell solar panel has obvious advantages in anti-shading performance compared with the conventional solar panel, especially in the case of full-width shading, the output power of the conventional module is almost zero, while the half-cell module still retains about half of the output power.
The anti-blocking performance of the half-cell solar panel is much better than that of the conventional solar panel which is due to its internal structure.
Half-cell solar panel circuit series-parallel structure
Full-cell solar panel circuit series structure
For the traditional solar panel design in a photovoltaic array, generally multiple solar panels are connected in series.
Once a module loses power due to various reasons of shadowing, it will affect all modules in the substring. Whereas in the half-cell solar panel pictured above, the bypass diode limits the power loss in the shaded part rather than the entire module, it creates an alternate path for current to flow in the non-shaded part and avoids the current passing through the shaded part, reducing the shadowed part. affect and improve its performance.
This feature of half-cell solar panel reduces the risk of hot spots. When a cell of a cell string in a conventional module is shaded, the cell forms a hot spot in the circuit, and sustained high temperatures may damage the module.
The half-cell module has twice the number of battery strings, which means that the heat at the hot spot is only half, and the lower heat causes less damage to the module, so it can improve the resistance to hot spot damage and increase the use of the module. life. The use of half-cell cells can provide great advantages and improved performance in shaded conditions, which is of great significance for building photovoltaics that are easily affected by other building obstacles.
What are the advantages of 10/11BB technology
Sunket 182mm 550W mono solar panel adopts multi-busbar technology. More busbars of the cell decrease the current transverse propagation path by 50%, effectively reduce the internal loss, and improve power of solar panels.

Sunket solar have been approved by many international and domestic authoritative certifications, such as ISO, TUV, CSA, CEC, IEC, CE, INMETRO, RETIE, JP-AC, DEWA, MCS and CQC Solar Product Certificates.
Our products are exported to Europe, Southeast Asia, the Middle East, Africa and South America and other countries and regions. The company also provides customized product service, which has won compliments from clients around the world.
High efficiency mono solar panel
In general, 182mm 550W high-power components take into account high power, high reliability, and high feasibility.
Using M10 high-efficiency monocrystalline cells, half-cell technology + 10/11 busbar and circular ribbon design to further reduce the distance between the busbar and the fine grid, reduce current loss, reduce power loss, effectively reduce shadow shading loss, work The temperature is low and the output power is high.
The 20.9% conversion efficiency of mass-produced modules, high power generation, reasonable labor costs, transportation costs and other advantages have become an optimized solution for low electricity costs in the market, which perfectly matches industrial and commercial photovoltaics and ground power stations.
