Highlights of the LONGi LR7-54HVBB-475M energy efficiency

• Outstanding 475 W nominal power: Delivers a reliable peak output of 475 W under standard test conditions (STC) for maximum power yields.
• Highly efficient 23.3% module efficiency: Achieves excellent area efficiency through state-of-the-art cell technology, generating significantly more solar power per square meter.
• Optimized low-light behavior: Generates a strong output of 361 W even under real weather conditions (NOCT) for consistently high everyday performance.
• Bifacial extra yields: Enables considerable additional power gains via the active rear side of the module, depending on the substrate and reflection.
• Positive power tolerance: With a guaranteed output tolerance of 0 to +3%, it offers the certainty that the nominal power will always be reached or exceeded during operation.

Highlights of mechanical stability & longevity

• Secure dual-glass structure: The combination of 2.0 mm semi-tempered front glass and 1.6 mm semi-tempered rear glass provides optimal protection for the solar cells against environmental influences and mechanical stress.
• Elegant black aluminum frame: The black anodized aluminum alloy frame not only ensures maximum torsional rigidity but also provides a timelessly elegant and homogeneous roof appearance.
• Extreme mechanical resilience: Certified for maximum static front loads of up to 5400 Pa and rear loads of up to 2400 Pa to effortlessly withstand extreme snow and wind loads.
• Superior weather protection: The IP68-certified junction box guarantees absolute dust and water tightness as well as durable cable connections.
• Outstanding hail resistance: Successfully tested with 25 mm hail stones at an impact velocity of 23 m/s for uncompromising protection during storms.

Technical specifications

Advantage for professionals: The LONGi Solar LR7-54HVBB-475M is the ideal module for future-proof and highly profitable photovoltaic projects. Thanks to the extremely low temperature coefficient of Pmax (-0.260%/°C), the module delivers maximum yields even on hot summer days, while the advanced dual-glass architecture minimizes degradation effects over the long term. With an enormous static front load capacity of 5400 Pa and the flexibly usable bifacial technology, it offers project planners and installers the highest level of planning security, shortened amortization periods, and uncompromising aesthetics on any type of system.
