Longi Photovoltaic Panel Assembly Size Parameters and Technical Specifications

Longi Photovoltaic Panel Assembly Size Parameters and Technical Specifications

Core Product Dimensions Across Longi's Portfolio

As the solar industry's equivalent of smartphone manufacturers debating screen sizes, Longi's photovoltaic components come in carefully engineered dimensions to balance power output with installation practicality. Let's dissect their current lineup:

• Hi-MO 5 Series (540-550W): 2256×1133×30mm (L×W×T) - The workhorse model with 21.3% efficiency
• Hi-MO 6 Series (445-455W): 2273×1134×30mm - Featuring anti-dust frame design
• Hi-MO 7 Series (585-590W): 2278×1134×30mm - Dual-glass construction at 31.8kg
• Next-Gen X6 Series: 2384×1303×30mm - Designed for 700W+ applications

The Weight-to-Power Sweet Spot

Imagine trying to install a refrigerator panel on your roof - that's why Longi keeps components under 32kg. The Hi-MO 7's 31.8kg weight allows two-person installation, while maintaining 22.8% efficiency through M10 silicon wafer optimization.

Technical Specifications Breakdown

Model	Power Output	Dimensions	Efficiency	Notable Tech
Hi-MO 5m	415W	2256×1133mm	21.3%	Gallium doping
Hi-MO X6	565-590W	2278×1134mm	22.8%	Double-glass construction

Current vs Legacy Models

The evolution from 540W to 660W components demonstrates Longi's technical leap:

• 660W Model: Operates at 60-70V open-circuit voltage
• 545W Legacy Unit: 13A working current vs 550W's optimized 13.99A
• DC Cable Specs: 4mm² conductors with 5Ω/km resistance at 40°C

Installation Considerations

When planning your solar array, remember these golden ratios:

1. Roof space vs power density: 550W panels cover ~2.56m²
2. Weight distribution: 31.8kg panels require 600mm rafter spacing
3. Electrical matching: 13A working current pairs with 15A breakers

The Dual-Surface Advantage

Longi's dual-glass models aren't just tougher - they're smarter. By harvesting reflected light, these panels achieve 5%+ efficiency gains. Pro tip: Pair with light-colored roofing for maximum backside illumination.

Industry Trends Impacting Dimensions

The solar world's current "size war" mirrors the flat-screen TV evolution. Longi's 2384×1303mm 700W+ prototypes showcase where the industry is heading:

• M10 wafer standardization
• 144-cell configurations
• Thinner busbar designs

However, installation crews might argue we're approaching practical size limits - maneuvering 2.3m panels requires careful planning and specialized equipment.
