Description
The LONGi Hi-MO 6 LR5-72HTH 565–585M Monofacial Solar Panel Series represents LONGi’s flagship generation of high-efficiency photovoltaic modules built specifically for rooftop solar systems.
Utilizing HPBC (Hybrid Passivated Back Contact) cell technology, all cell electrodes are moved to the rear side of the wafer. This design eliminates front-side busbar shading, increases light absorption area, and yields a high module conversion efficiency of up to 22.7%. The 144 half-cut cell arrangement (6 × 24) significantly reduces internal electrical resistance losses and optimizes performance under partial shading conditions.
In Bangladesh, where industrial and commercial electricity costs are rising and roof space is often limited, the LONGi Hi-MO 6 series provides an exceptional solar solution. Its superior low-light power generation and ultra-low temperature coefficient ensure maximum kilowatt-hour generation throughout the year, making it perfect for net-metering projects under local grid guidelines.
