LONGi LR8-66HGD-610M 610W Hi-MO 7 Bifacial Solar Panel

LONGi LR8-66HGD-610M 610W Bifacial Half-Cut Mono Solar Panel

The LONGi LR8-66HGD-610M 610W Bifacial Solar Panel belongs to the Hi-MO 7 series and is designed for large commercial and utility-scale photovoltaic installations. Combining HPDC cell technology, half-cut cells and dual-glass construction, this module offers a rated maximum power output of 610W and a stated module efficiency of up to 22.6%.

For solar developers, industrial facilities and commercial project owners in Bangladesh, the LONGi 610W bifacial solar panel can be considered for suitable ground-mounted solar farms and large rooftop installations. Its bifacial design allows the rear surface to capture reflected sunlight, potentially increasing total energy generation when the installation provides favorable rear-side illumination.

Advanced HPDC Cell Technology

The LR8-66HGD-610M features HPDC cell technology according to the supplied product information. Combined with a half-cut cell design, this module is intended for high-output solar applications where efficient energy generation and reliable operation are important.

With a rated power output of 610W, each module contributes to the total DC capacity of the solar array. The number of panels required depends on the target system capacity, available installation area, expected electricity demand and the design of the complete photovoltaic system.

Bifacial Performance and Energy Generation

The panel features a bifacial design with a stated bifaciality rating of 80 ± 5%. This allows the rear side to contribute to power generation when reflected or scattered sunlight reaches the module's rear surface.

Actual bifacial energy gain depends on factors such as ground reflectivity, mounting height, row spacing, rear-side clearance, shading and site conditions. The potential additional generation should therefore be evaluated during project design rather than treated as a guaranteed output increase.

Electrical Performance and System Compatibility

The LONGi LR8-66HGD-610M has a voltage at maximum power (Vmp) of 40.50V and a current at maximum power (Imp) of 15.81A. Its open circuit voltage (Voc) is 48.59V, while its short circuit current (Isc) is 15.86A.

The supplied specifications list a maximum system voltage of 1500V DC under IEC/UL conditions and a maximum series fuse rating of 25A. These values are important when designing solar strings and selecting compatible inverters, cables, connectors and protection devices.

Before installation, confirm the inverter's maximum PV input voltage, operating voltage range, input current limits and permitted array capacity. String configurations must comply with the equipment manufacturer's requirements and applicable electrical standards.

Durable Dual-Glass Construction

This solar panel measures 2382 × 1134 × 30mm and weighs approximately 33.5kg. 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 can help engineers assess the module for a particular project, but the mounting structure and fixing arrangements must also meet site-specific wind loads, structural requirements and installation standards.

The stated operating temperature range is -40°C to +85°C. Actual energy production will vary with sunlight intensity, module temperature, shading and other environmental factors.

Warranty and Long-Term Reliability

The supplied information states a 12-year product warranty and a 30-year linear power performance warranty. It also lists first-year power degradation of less than 1%, followed by annual degradation of 0.4% from years 2 through 30.

Buyers should review the official LONGi warranty documents to confirm the precise power retention schedule, coverage, exclusions and claim conditions before purchasing.

Applications in Bangladesh

The LONGi LR8-66HGD-610M may be suitable for industrial rooftops, commercial facilities, ground-mounted solar farms and other high-capacity photovoltaic projects in Bangladesh where its electrical and mechanical specifications meet project requirements.

For bifacial installations, project designers should evaluate rear-side clearance, reflective ground surfaces, mounting height and shading. For rooftop projects, verify the roof's structural capacity and the compatibility of the mounting system before installation.

When purchasing the LONGi 610W 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.
