Solar Panel

Sunnal mono half-cut single/double glass module,assembled with multi-busbar PERC technique and half-cut structure, which can not only absorb the energy from the front of the module, but also absorb the reflected light and the scattered light from the back，offer the advantages of higher power output,reduce shading effect on the energy generation,enhance the mechanical load bearing capacity as well.

The overall design with exquisite appearance can increase the effective light absorption of the product and increase power generation efficiency.

Half Cut Technology: Under the same shadow condition, power loss of half-cell solar panel is less than that of full cell solar panel. 

Multi Busbar Technology: MBB technology improves efficiency of modules, offers a better aesthetic appearance. 

PERC Technology: The PERC cell has a passivated rear side and a laser grooving process, which significantly improves the cell efficiency.

The Sunnal solar panels are manufactured using monocrystalline technology, which is known for its high efficiency and durability. Monocrystalline solar panels are made from a single crystal of silicon, and their uniform structure allows for better electron flow and higher energy conversion rates.

The solar panels have a total output of 555W and come with a 12-year product warranty and a 25-year performance warranty. Thanks to the 210mm PERC cells, the module efficiency is 21.7%. You can generate a lot of green electricity if you set up the system in a sunny location.

Enhanced with cutting-edge technology, the product features the high-efficiency 182 series PERC cell half-cell technology, resulting in increased output power and exceptional performance when it comes to shielding loss and temperature coefficient. Furthermore, by utilizing advanced cell-cutting technology, the risk of hot spots in high-power components has been significantly reduced, ultimately leading to better power generation performance in system applications along with enhanced reliability.
