LONGi LR4-72HBD-445M 445W Bifacial Half-Cut Mono Solar Panel

LONGi LR4-72HBD-445M 445W Bifacial Half-Cut Mono Solar Panel

The LONGi LR4-72HBD-445M 445W Bifacial Half-Cut Mono Solar Panel is designed for commercial photovoltaic installations and ground-mounted solar power projects. Combining monocrystalline Mono PERC technology, half-cut cells and a bifacial dual-glass structure, this module offers a rated maximum power output of 445W and a stated module efficiency of up to 21.0%.

For solar installers, businesses and project developers in Bangladesh, the LONGi 445W bifacial solar panel can be considered for suitable commercial rooftops, ground-mounted arrays and other photovoltaic applications. Its bifacial design allows the rear surface to capture reflected sunlight, potentially increasing total energy generation when the installation provides appropriate rear-side illumination.

Bifacial Half-Cut Mono PERC Technology

The LR4-72HBD-445M combines half-cut monocrystalline PERC cells with a bifacial module design. The supplied specifications state a bifaciality rating of 70 ± 5%, indicating the rear side's power capability relative to the front side under specified test conditions.

The product information also mentions bifacial gain of up to 25%. Actual additional energy generation is not guaranteed and depends on ground reflectivity, mounting height, row spacing, shading, panel orientation and other site conditions.

With a rated power output of 445W, the module can contribute to solar arrays designed around a project's target capacity and available installation space.

Electrical Performance and System Compatibility

The LONGi LR4-72HBD-445M has a voltage at maximum power (Vmp) of 41.2V and a current at maximum power (Imp) of 10.80A. Its open circuit voltage (Voc) is 49.4V, while its short circuit current (Isc) is 11.72A.

The module is rated for a maximum system voltage of 1500V DC and a maximum series fuse rating of 25A, according to the supplied information. These ratings are important when designing solar strings and selecting compatible inverters, charge controllers, cables and electrical protection equipment.

Before installation, verify the selected inverter's maximum PV input voltage, operating voltage range, current limits and allowable array capacity. String configurations must remain within the equipment manufacturer's requirements and applicable electrical standards.

Durable Dual-Glass Construction

This LONGi solar panel measures 2094 × 1038 × 35mm and weighs approximately 27.5kg. Its dual-glass construction is designed for outdoor photovoltaic applications, while the IP68-rated junction box provides protection against dust and water ingress under the applicable rating conditions.

The stated mechanical load ratings are 5400Pa on the front side and 2400Pa on the rear side. These specifications can help engineers evaluate the panel for a particular project, but mounting structures and fixing arrangements must still be selected according to site conditions and relevant building requirements.

The specified operating temperature range is -40°C to +85°C. Actual energy production varies with sunlight, shading, module temperature, installation angle and environmental conditions.

Warranty and Long-Term Performance

The supplied product information states a 12-year product warranty and a 30-year linear power performance warranty. Buyers should review the applicable LONGi warranty documentation to confirm the exact coverage, performance degradation schedule, exclusions and claim requirements before purchasing.

Applications in Bangladesh

The LONGi LR4-72HBD-445M may be suitable for commercial solar systems, ground-mounted solar farms, industrial facilities and other projects where its electrical and mechanical specifications meet the design requirements.

To benefit from its bifacial construction, installers should consider reflective ground surfaces, rear-side clearance, mounting height and shading when planning the array. For rooftop projects, structural capacity and mounting compatibility should be assessed before installation.

When purchasing the LONGi 445W bifacial solar panel from Muthobd.com, confirm product availability, warranty documentation and system compatibility before placing an order. Professional system design and installation help support safe operation and dependable solar power generation.
