LONGi 610W Bifacial Solar Panel

LONGi 610W Bifacial Solar Panel Overview

The LONGi 610W Bifacial Solar Panel is a high-output photovoltaic module developed for utility-scale, commercial and industrial solar installations. It belongs to the Hi-MO X7 series and uses advanced HPDC cell technology to deliver a combination of power output, module efficiency and long-term performance.

With a rated capacity of 610 watts and a module efficiency of 22.6%, this panel helps solar project developers generate substantial power from each installed module. Its bifacial construction also allows it to capture sunlight from the rear side when the installation surface and surrounding conditions provide sufficient reflected light.

The panel features a dual-glass structure, an anodized aluminium alloy frame and half-cell architecture. These design elements make it suitable for projects where mechanical strength, electrical performance and long-term operation are important considerations.

For Pakistani buyers planning a commercial rooftop, industrial solar plant or ground-mounted installation, the panel offers a combination of high wattage, bifacial energy generation and a clearly defined long-term power warranty.

Key Features and Benefits

Advanced HPDC Cell Technology

The LONGi Hi-MO X7 series uses HPDC cell technology to combine high module power with efficient solar energy conversion.

The 610W model achieves 22.6% module efficiency, helping project developers make effective use of the available installation area. Correct string design, orientation and installation conditions remain important for achieving the expected energy yield.

Bifacial Energy Generation

The bifacial solar panel design enables the module to generate electricity from both its front and rear sides.

Rear-side energy production depends on factors such as ground reflectivity, mounting height, row spacing, shading and installation layout. Light-coloured surfaces and a suitable mounting arrangement may improve rear-side energy gain.

The panel has a bifaciality rating of 80 ± 5%, which describes its rear-side electrical performance relative to the front side under specified testing conditions. It does not represent a guaranteed percentage increase in total system energy.

High Module Efficiency

With 22.6% efficiency, the panel converts a substantial portion of the sunlight reaching its active surface into electricity.

This is particularly useful for commercial and industrial projects where available space, mounting structures and total installed capacity influence system design.

Half-Cell Design

The module uses a 132-cell arrangement (6 × 22) and half-cell architecture. This design supports electrical performance while helping manage operating characteristics within the module.

Actual generation still depends on sunlight, temperature, shading, cleanliness and the overall solar system configuration.

Dual-Glass Construction

The panel features 2.0 + 2.0 mm heat-strengthened glass on its front and rear sides, along with an anodized aluminium alloy frame.

Its glass construction is suitable for projects requiring a robust module design. Proper handling, transport, mounting and installation remain essential to protect the panel from damage.

Low Power Degradation

The panel carries a 30-year linear power output warranty. Its stated degradation figures include less than 1% power degradation during the first year and 0.4% annual degradation from years 2 through 30.

These figures provide buyers with a basis for evaluating long-term power performance. Actual output varies with operating conditions and installation quality.

Best For

The LONGi 610W Bifacial Solar Panel is suitable for:

• Commercial solar installations requiring high-output modules.

• Industrial solar systems designed to reduce daytime electricity consumption.

• Ground-mounted solar projects where rear-side light exposure can be optimised.

• Utility-scale solar plants requiring high-capacity photovoltaic modules.

• Large rooftop installations with sufficient space and suitable structural support.

• Solar installers and project developers who need verified electrical specifications for string planning.

Its larger physical dimensions and 610W rating should be considered before selecting it for a particular mounting structure or inverter configuration.

When Another Panel May Be Better

This panel may not be the most suitable choice when:

• The installation requires smaller module dimensions.

• The mounting structure cannot support the panel’s size and weight.

• The inverter has lower allowable DC input current than the proposed string configuration requires.

• Rear-side sunlight is heavily obstructed and bifacial energy generation is an important project objective.

• The installation requires different voltage or current characteristics.

Before purchasing, check the panel’s electrical limits against the selected inverter and the complete system design.

Cell and Module Technology

The LONGi Hi-MO X7 610W combines HPDC cell technology with bifacial module construction.

Its 132-cell arrangement and dual-glass design support the requirements of larger solar installations. The bifacial configuration provides an opportunity to capture additional rear-side irradiance, depending on the mounting environment.

The module’s rated electrical characteristics are important when configuring strings. The maximum open-circuit voltage, operating current and temperature behaviour must all be considered when deciding how many modules to connect in series and how to distribute strings across inverter inputs.

A qualified installer should verify the design against the inverter’s maximum DC voltage, MPPT operating range and current limits.

Technical Specifications

Performance and Degradation

Long-term power retention is an important consideration when evaluating a solar panel for a commercial or industrial project.

The LONGi 610W Bifacial Solar Panel has a first-year power degradation figure of less than 1%, followed by 0.4% annual degradation from the second through the thirtieth year.

The stated power-retention figures are:

• First-year degradation: Less than 1%.

• Annual degradation from years 2–30: 0.4%.

• Power output at year 10: 95.4%.

• Power output at year 20: 91.4%.

• Power output at year 30: 87.4%.

These values describe the panel’s stated linear power performance. They should not be interpreted as a guarantee of the complete solar system’s electricity production, which also depends on weather, shading, inverter performance, maintenance and other operating conditions.

The -0.280%/°C temperature coefficient of Pmax is also relevant in Pakistan, where module temperatures can rise significantly during summer. Actual output changes with cell temperature and solar irradiance.

Performance Considerations for Pakistan

Solar panels installed in Pakistan must be selected and installed with local temperatures, dust and mounting conditions in mind.

High summer temperatures: The panel’s temperature coefficient of Pmax is -0.280%/°C. Module temperature therefore matters when estimating output under hot operating conditions.

Dust and cleaning: Dust accumulation can reduce sunlight reaching the solar cells. Regular inspection and appropriate cleaning help maintain energy production.

Bifacial installation: Rear-side output depends on ground reflectivity, module elevation, row spacing and shading. The mounting arrangement should allow suitable light exposure behind the panel.

Ventilation: Adequate airflow behind the modules can help limit operating temperature. Avoid mounting arrangements that unnecessarily restrict ventilation.

Electrical design: The panel’s Voc, Vmp, Isc and Imp should be checked against inverter specifications, including temperature-adjusted string voltage and input-current limits.

These considerations help installers design a solar system around the panel’s actual electrical characteristics rather than its wattage alone.
