LONGi LR5-72HBD-545M 545W Bifacial Half-Cut Mono Solar Panel

LONGi LR5-72HBD-545M 545W Bifacial Half-Cut Mono Solar Panel

The LONGi LR5-72HBD-545M 545W Bifacial Half-Cut Mono Solar Panel belongs to the Hi-MO 5 series and is designed for large-scale solar power plants and high-capacity commercial installations. It combines monocrystalline half-cut cells, M10 gallium-doped wafer technology and dual-glass construction to support efficient solar energy generation.

With a rated maximum power output of 545W and a stated module efficiency of up to 21.3%, this LONGi solar panel can be considered for industrial facilities, commercial solar systems and ground-mounted photovoltaic projects in Bangladesh.

Bifacial Technology and High Power Output

The LR5-72HBD-545M features a bifacial design that allows the rear surface to capture reflected sunlight in addition to the light received by the front surface. The additional energy generated depends on installation conditions, including ground reflectivity, mounting height, row spacing, shading and rear-side illumination.

Its rated 545W output makes the module suitable for system designs that require high-wattage solar panels. The number of modules required for a project depends on the target DC capacity, available space, expected energy consumption and the design of the complete solar installation.

M10 Wafer and Half-Cut Cell Design

According to the supplied product information, the LONGi Hi-MO 5 module uses M10 gallium-doped wafers and a 9-busbar half-cut cell configuration. These design features are intended to support module performance and electrical reliability.

The module has a stated efficiency of up to 21.3%. Actual energy production will vary according to solar irradiation, panel orientation, shading, operating temperature and installation conditions.

Electrical Performance and Compatibility

The LONGi LR5-72HBD-545M has a voltage at maximum power (Vmp) of 46.98V and a current at maximum power (Imp) of 11.61A. Its open circuit voltage (Voc) is 49.65V, while its short circuit current (Isc) is 13.29A.

The supplied specifications list a maximum system voltage of 1500V DC under IEC/UL conditions and a maximum series fuse rating of 30A. These ratings are important when designing solar strings and selecting compatible inverters, cables, charge controllers and protective equipment.

Before installation, verify the selected inverter's maximum PV input voltage, operating voltage range, input current and permitted solar array capacity. All string configurations must remain within the equipment manufacturer's specified limits.

Durable Dual-Glass Construction

This solar panel measures 2256 × 1133 × 35mm and weighs approximately 32.6kg. Its dual-glass construction and IP68-rated junction box are specified for outdoor photovoltaic applications.

The stated maximum mechanical load ratings are 5400Pa on the front side and 2400Pa on the rear side. These values help with project assessment, but the mounting structure and fixing system must also meet site-specific wind loads, structural requirements and applicable installation standards.

The panel's stated operating temperature range is -40°C to +85°C. Actual operating performance depends on environmental conditions and system design.

Warranty and Long-Term Performance

The supplied information specifies a 12-year product warranty and a 30-year linear power performance warranty. It also lists first-year power degradation of less than 2% and subsequent annual degradation of 0.45% for years 2–30.

Buyers should review the official warranty documents to confirm the exact degradation schedule, coverage, exclusions and claim conditions before purchasing.

Applications in Bangladesh

The LONGi LR5-72HBD-545M may be suitable for industrial rooftops, commercial buildings, ground-mounted solar farms and other high-capacity solar projects where its electrical and mechanical specifications meet the project requirements.

For bifacial installations, system designers should consider rear-side clearance, reflective ground surfaces, mounting height and shading to improve the potential benefit of the bifacial design. For rooftop projects, verify the roof's structural capacity and mounting compatibility.

When purchasing the LONGi 545W bifacial solar panel from Muthobd.com, confirm product availability, warranty documentation and compatibility with the intended inverter and mounting system. Proper engineering and professional installation help support safe operation and dependable solar power generation.
