Longi LR7-72HGD 615M Bifacial White, LR5, 1.4m, Hi-MO X6 Max

Tiered Pricing available this Price is for 1 to 35 units

The Longi LR7-72HGD-615M (Bifacial White) is a high-power dual-glass bifacial solar module from the Hi-MO 7 series. It features HPDC (High Performance Dual Cell) n-type TOPCon-based technology with 144 half-cut cells (72 equivalent full cells in a 6×24 layout). The "White" refers to its bifacial design with a white/transparent backsheet or clear glass appearance for better rear-side light capture, paired with a silver anodized aluminum frame (30 mm height). It targets commercial, industrial, and utility-scale projects, including ground-mount or large rooftop installations.

Performance and FeaturesThis module delivers strong energy yield through:

Bifacial gain — Up to 10–30% extra output depending on albedo (ground reflectivity), mounting height, and surface (e.g., white gravel, snow, or sand). The high bifaciality (~80%) and clear rear design help capture reflected light effectively.
Low temperature coefficient (-0.28%/°C) combined with half-cut cells for reduced resistive losses and lower operating temperatures.
High power density — Reduces BOS (balance-of-system) costs: fewer modules, less racking, cabling, and land needed for the same capacity (Longi claims ~4.5% power uplift vs. prior generations).
Good low-light and high-temperature behavior, making it suitable for diverse climates, including hot/humid areas.

Longi positions the Hi-MO 7 series for utility power plants with emphasis on lifecycle quality, PID resistance, and overall LCOE (levelized cost of energy) reduction.DATA SHEET
