Lesso New Energy 650D(HPM) 645W–665W P-Type Monofacial Solar Panel
Model 650D(HPM) | P-Type Monocrystalline | 132 Half-Cell | Monofacial | 1500V System Voltage
Product Overview
The Lesso New Energy 650D(HPM) is a high-output p-type monofacial solar panel built for dependable utility and commercial performance. It delivers a power range from 645W to 665W, with a maximum module efficiency of 21.41%. The module uses 210mm mono-crystalline half cells and a 132-cell layout for strong energy capture. Its design supports lower resistance losses, better shade tolerance, and stable operation in demanding outdoor environments. With a 12-year product warranty and a 25-year linear power output warranty, this panel is suited for long-term solar projects that need consistent generation and strong value.
Key Benefits
High power range: The module offers 645W to 665W output for large-scale installations.
Strong shade tolerance: MBB half-cut cell technology improves performance under partial shading.
Lower hotspot risk: Series and parallel cell design helps reduce electrical stress and heat concentration.
Better weather durability: Harsh weathering tests support resistance to sand, dust, salt mist, and ammonia.
Improved energy yield: Lower temperature coefficient helps maintain generation in hot operating conditions.
Reduced degradation: The panel features 2% first-year degradation and 0.55% annual degradation afterward.
How It Works
This solar panel converts sunlight into usable electricity through advanced p-type mono-crystalline cells. Its half-cut cell layout reduces internal current loss and improves response under uneven light conditions. The multi-busbar structure supports better current collection and lower series resistance. That helps the panel produce more usable power across the day. The module also uses durable materials and protective construction to support stable output in harsh weather. Together, these features improve generation, reliability, and long-term system performance.
MBB half-cut cell layout: The module splits cells to reduce current flow in each path. This lowers resistance and improves shade handling.
Series and parallel design: The electrical layout balances power delivery across the module. It supports higher output and lower balance-of-system cost.
Protective material system: Controlled raw materials and optimized processing help reduce PID and LID. This supports more stable performance over time.
