High Efficiency 475W Solar Panel
The LR7-54HVB-475M delivers 475W of rated output with 23.3% module efficiency under standard test conditions.
This high efficiency allows more generation capacity to be installed within a given roof area, making the module particularly suitable for residential installations where usable roof space may be limited.
LONGi identifies high power generation under the same installation area as one of the principal advantages of its HPBC 2.0 technology.
Module Efficiency by Model
| Model | Rated Power | Module Efficiency |
|---|---|---|
| LR7-54HVB-475M | 475W | 23.3% |
| LR7-54HVB-480M | 480W | 23.5% |
| LR7-54HVB-485M | 485W | 23.8% |
| LR7-54HVB-490M | 490W | 24.0% |
| LR7-54HVB-495M | 495W | 24.3% |
These values are specified under STC conditions of AM1.5, 1000 W/m² irradiance and 25°C cell temperature.
Advanced HPBC 2.0 Back-Contact Cell Technology
The LONGi EcoLife X10 LR7-54HVB series uses HPBC 2.0 back-contact cell technology.
Back-contact architecture moves the electrical contacts away from the visible front surface of the cells. This contributes to the module’s clean gridless appearance while allowing more of the front cell area to remain available for light absorption.
LONGi highlights HPBC 2.0 as a key reason for the series’ high power generation, describing the technology as capable of providing more generation under the same module area.
For customers comparing premium residential solar modules, the LR7-54HVB-475M combines: N-type technology + HPBC 2.0 + high module efficiency + single-glass construction + pure black aesthetics.
Anti-Shading and Localised Overheating Protection
Partial shading can affect the performance of photovoltaic modules when objects such as trees, roof structures, antennas or surrounding buildings block part of the solar panel.
LONGi specifically identifies anti-shading performance and prevention of localised overheating as safety features of the EcoLife X10 series.
This design focus is particularly relevant for residential rooftop systems, where modules can experience varying shading conditions throughout the day.
Lower Operating Temperature Characteristics
LONGi identifies the BC-cell design used in the LR7-54HVB series as having lower operating temperature characteristics.
Lower cell operating temperatures can be beneficial because solar module power output generally declines as cell temperature rises.
The datasheet specifies a Pmax temperature coefficient of: -0.260%/°C
This means the module’s maximum power output decreases by approximately 0.260% for every 1°C increase in cell temperature above the reference test condition.
Excellent Long-Term Power Retention
Long-term degradation is an important consideration when evaluating solar panel lifetime performance.
LONGi specifies:
First-year degradation: less than 1%
Annual degradation from years 2–30: 0.35%
Guaranteed power after 30 years: 88.85%
The power warranty chart on page 2 of the datasheet shows the module retaining 88.85% of its rated power at year 30.
This degradation profile helps the LR7-54HVB-475M maintain a high proportion of its original output over decades of operation.
Single Glass Construction
The LR7-54HVB-475M uses a single-glass module structure with:
Front glass: 3.2 mm coated tempered glass
Frame: black anodised aluminium alloy
The 3.2 mm front glass also contributes to the module’s hail resistance, with LONGi specifically highlighting higher hail resistance as one of the features of the EcoLife X10 series.
Compared with the dual-glass LR7-54HVD version, the LR7-54HVB has a lower module weight of 21.6 kg while maintaining the same 1800 × 1134 mm footprint.
Pure Black, Gridless Appearance
Appearance is an important consideration for premium residential rooftop installations.
LONGi describes the EcoLife X10 series as having a “Pure Black Appearance” with no gridlines and low glare.
The back-contact cell architecture removes conventional front-side electrical gridlines from view, producing a cleaner and more uniform surface.
Combined with the black anodised aluminium frame, the LR7-54HVB-475M provides a modern all-black look designed to integrate well with contemporary residential roofs.
LONGi positions the series as a first choice for high-end residential applications.
Strong Mechanical Load Performance
The LONGi LR7-54HVB-475M is engineered to withstand substantial mechanical loading.
Maximum Static Load
Front side: 5400 Pa
Rear side: 2400 Pa
The datasheet also specifies successful hail testing using: 25 mm hailstones travelling at 23 m/s . These specifications are important for rooftop solar modules that may be exposed to wind, snow, hail and other environmental stresses during their service life.
Temperature Performance
The LR7-54HVB series has a nominal operating cell temperature of: 45 ±2°C
