Product Description

LONGi LR4-72HPH 445-465W solar panel

LONGi LR4-72HPH 445-465W solar panel is a high-efficiency monocrystalline photovoltaic module from LONGi Hi-MO 4 series. Designed with advanced half-cell PERC technology, the module delivers higher power output, improved reliability, and better energy yield compared with conventional full-cell modules.

Featuring 144 half-cut monocrystalline cells, the LR4-72HPH series reduces internal electrical losses and improves module performance under different operating conditions. With a maximum power output of 465W and module efficiency up to 21.4%, it provides an efficient solution for residential rooftops, commercial installations, and utility-scale solar projects.

The module supports a 1500V DC maximum system voltage, offers excellent temperature performance from -40℃ to +85℃, and withstands harsh environmental conditions with strong mechanical durability. Its optimized design ensures stable power generation throughout the module lifetime.
