Photovoltaic module LONGi Solar Hi-MO4m 450 W

LONGi Solar LR4-72HIH-450Mis a high efficiency monocrystalline photovoltaic module of the seriesHi-MO4m, developed withMono PERC Half-Celltechnology for maximum performance and reliability. Split cells reduce internal resistance and electrical losses, resulting in higher energy yield and better performance in partial shading.

The module uses Low LID PERC cells with improved resistance against the PID effect, which ensures slower degradation and stable operation throughout the service life. Thanks to the robust construction, high mechanical resistance and excellent electrical characteristics,LR4-72HIH-450Mis suitable for residential, commercial and industrial photovoltaic systems.
