Longi 450 Watt Solar Panel

Longi LR4-72HPH-450M (Blue cells) monocrystalline solar module

  • Rated Power:  450W
  • Output Warranty Term:  25 years, Linear
  • Materials Warranty Term:  12 years


The LONGi HPH Series combines High Efficiency, Low LID Mono PERC cells with Half-cut Technology to improve performance and boost production. This module series has a max system voltage of 1500V and a UL Type 4 Fire Rating. 35mm frames reduce weight while still providing the strength and resilience needed to rate 5400Pa for front side static loading and 2400Pa for rear side static loading. LR4-72HPH-450M- Longi Solar 450w Mono Half-Cell PERC Solar Panel provides high reliability, production efficiency, and higher power output along with lower hot spot temperature because of low working current.Reduced hot spot risk with optimized electrical design and lower operating current. The Longi Solar 450W Mono half-cell PERC solar panel is an excellent all-rounder that can be used for a variety of purposes. The panel utilizes a blend of monocrystalline cells and polycrystalline cells to merge the best characteristics of each cell into one panel. This creates a product that has a high tolerance for shading, great durability, and increased efficiency when compared to traditional mono-crystalline or poly-crystalline solar panels. The Longi Solar 450w Mono Half-Cell PERC Solar Panel is a solar panel system designed for home use in South Africa. This Longi Solar 450w Mono Half-Cell PERC Solar Panel is an excellent choice for increasing the energy output at a residence or business.

Longi Solar 450W Solar Panels are designed to withstand extreme climate conditions and are ETL verified, tested for IEC 61215 Ed.2 standard for safety as well as the fire safety inside a rail container (UN 38.3). Longi Solar 450w Mono Half-Cell PERC Solar Panel is a leading solar panel manufacturer, improving the quality of life through Green Power. The Longi Solar 450w mono solar panel is a high efficient solar panel, with its highest efficiency of up to 21.2%, generates the highest power density in the industry.
