Product Overview

High-efficiency BC technology, engineered for practical rooftop applications.

 
 

The LR7-72HVHF series is a 640–670W BC-cell monocrystalline module equipped with HPBC 2.0 cell technology. The product combines high module efficiency with a construction focused on long-term reliability and stable operation. With efficiency reaching 24.8% on the 670W version, the series is designed to deliver high power density while keeping the module format suitable for commercial and industrial rooftop applications.

 
 
 

A distinctive feature of the series is its frame design, which is intended to effectively reduce the impact of dust accumulation. This design consideration is particularly relevant to real-world installations where dust can accumulate on module surfaces and influence energy generation over time.

 
 
 

The datasheet specifically identifies industrial and commercial color steel tile roofs and small-angle installation scenarios as suitable applications. This makes the LR7-72HVHF a strong fit for project environments where roof characteristics, installation angle and long-term operating conditions need to be considered together.

 

 

Key Advantages
 

High Power Density for Space-Constrained Roofs

With a power range of 640W to 670W and maximum module efficiency of 24.8%, the LR7-72HVHF series is designed to make effective use of available installation area. For commercial and industrial rooftops, higher power per module can help project designers achieve the required system capacity without relying solely on additional roof area.

Testing conditions stated in the datasheet: STC at AM1.5, 1000W/m² and 25°C; NOCT at AM1.5, 800W/m² and 20°C. Test uncertainty for Pmax is stated as ±3%.

 

Performance in Real-World Conditions

 

 

Solar modules operate under changing irradiance and temperature rather than laboratory conditions alone. For project evaluation, temperature coefficients, operating temperature and mechanical ratings provide important context for how the module is specified for outdoor use.

 

Temperature Performance

 

 

The module's temperature coefficients are specified as +0.050%/°C for Isc, -0.200%/°C for Voc and -0.260%/°C for Pmax. The Pmax coefficient indicates how maximum power changes with temperature and provides a technical reference for system designers evaluating module behavior across different operating temperatures.

 

Wide Operating Temperature Range

 

 

The specified operating temperature range is -40°C to +85°C, while the nominal operating cell temperature is 45 ± 2°C. Together, these specifications define the module's intended operating envelope for outdoor installations.

 

Mechanical and Hailstone Resistance

 

 

The module is rated for a maximum static loading of 5400Pa on the front side and 2400Pa on the rear side. The datasheet also specifies a hailstone test using a 25mm hailstone at a speed of 23m/s. These ratings provide project engineers with defined mechanical-performance references when assessing installation conditions.

 

Recommended Applications

Industrial & Commercial Color Steel Tile Roofs

The LR7-72HVHF series is explicitly positioned for industrial and commercial color steel tile roofs. Its high power output and compact module format make it suitable for projects where available roof area and installation conditions are important design considerations.

Small-Angle Installation Scenarios

The datasheet also identifies small-angle installation scenarios as a suitable application. This gives the product a clear positioning for rooftop projects where module mounting conditions may differ from standard high-tilt configurations.

Projects Requiring High Efficiency

With efficiency reaching 24.8%, the series is suited to buyers seeking a high-efficiency module platform for commercial and industrial applications. The availability of seven power classes from 640W to 670W also allows procurement teams to select a suitable rating within the same series.

Controlled Power Degradation

The datasheet specifies less than 1% power degradation during the first year and 0.35% annual degradation from year 2 through year 30. These figures provide buyers with a clear framework for evaluating the module's long-term power-retention proposition.

A 30-Year Power Proposition

The 30-year linear power warranty is designed to support long-term project planning. For commercial and industrial project owners, a defined long-term power warranty can be an important part of evaluating expected asset performance and supplier risk.
