Lesso New Energy 645D(HPM) 645–665W P-Type Monofacial Solar Panel
Model 645D(HPM) | P-Type Monocrystalline | 132 Half-Cell | Monofacial | 1500V System Voltage
Product Overview
The Lesso New Energy 645D(HPM) is a high-output P-type monofacial solar panel built for demanding commercial and utility projects. It uses 210mm monocrystalline half-cells and delivers a power range from 645W to 665W. The module is designed for strong field performance, stable energy generation, and efficient installation. With up to 21.41% module efficiency, it supports excellent power density in large PV systems. The panel also includes a durable glass, aluminum, and IP68-rated construction. Its 12-year workmanship warranty and 25-year linear power output warranty add long-term confidence. This module is suitable for projects that need reliable output, lower system balance costs, and consistent operating performance.
Key Benefits
High Power Output: Delivers 645W to 665W for strong energy generation in larger solar arrays.
Improved Shade Response: MBB half-cut cell architecture helps reduce shade losses and hot-spot risk.
Higher System Value: Series and parallel design lowers resistance and helps improve BOS cost efficiency.
Strong Weather Resistance: Tested against sand, dust, salt mist, and ammonia for outdoor durability.
Stable Long-Term Output: Low first-year degradation and controlled annual degradation support reliable production.
Lower Temperature Losses: A lower temperature coefficient supports better performance in warm conditions.
How It Works
This module converts sunlight into electricity through 210mm monocrystalline half-cells arranged in a 132-cell format. The half-cut structure reduces internal current flow and helps improve electrical behavior. Multi-busbar design supports stronger current collection and better shading tolerance. P-type PERC processing is used to help increase efficiency and maintain output stability. The panel is built with anti-reflective tempered glass, an anodized aluminum frame, and an IP68 junction box. These components help protect the module during long-term outdoor exposure. The result is dependable power generation, lower losses, and smoother system performance across the project lifecycle.
MBB Half-Cut Cells: The cells are split and arranged to reduce series resistance. This supports better power output and lower hot-spot risk.
PERC Cell Processing: High-efficiency PERC technology improves light conversion. It also supports better PID resistance in field conditions.
Weather-Ready Construction: The module is tested for dust, salt mist, sand, and ammonia exposure. This helps maintain performance in harsh outdoor environments.
