LONGi 605W Bifacial Solar Panel

LONGi 605W Bifacial Solar Panel Overview

The LONGi 605W Bifacial Solar Panel is designed for solar installations that require high power output from individual modules. Its 605W rating makes it a practical option for commercial rooftops, industrial facilities and ground-mounted solar projects where the number of panels, available space and electrical system design all matter.

This module uses a bifacial design, allowing sunlight to reach both sides of the panel. The front side captures direct sunlight, while the rear side can contribute additional electricity from reflected and scattered light. The actual rear-side contribution depends on the mounting height, ground surface, spacing, shading and surrounding installation conditions.

With 22.4% module efficiency, dual-glass construction and a 30-year linear power output warranty, the panel is suited to projects planned for long-term energy production. Correct string configuration and suitable mounting are essential to achieve reliable system performance.

Key Features and Benefits

605W High Power Output

The panel provides a rated output of 605 watts under Standard Test Conditions (STC). Higher-wattage modules can help reduce the number of panels required for a given DC capacity, subject to the project’s electrical design and available installation area.

This can be useful for installers and commercial buyers planning larger solar arrays.

Bifacial Solar Generation

The 80 ± 5% bifaciality rating describes the relationship between the rear-side and front-side power ratings under the relevant test conditions. It does not mean that the panel automatically produces 80% more electricity.

Rear-side energy production varies with reflected sunlight, ground reflectivity, panel elevation, row spacing and shading. A suitable mounting arrangement helps make better use of the bifacial design.

22.4% Module Efficiency

The 22.4% efficiency rating indicates how effectively the module converts the sunlight received under standard test conditions into electrical power. Higher module efficiency can help make productive use of limited installation space.

Actual daily and annual energy generation depends on sunlight, module temperature, orientation, shading, dust and system losses.

Dual-Glass Construction

The module uses 2.0 mm + 2.0 mm heat-strengthened glass on its front and rear sides. This construction is suitable for projects where a glass-glass module design is required.

The panel also features an anodized aluminium alloy frame and an IP68-rated junction box with three bypass diodes.

Low Power Degradation

The panel has a specified first-year power degradation of less than 1%, followed by 0.4% annual degradation from years 2 to 30. This supports long-term project planning, although actual output can vary with environmental conditions, installation quality and operating history.

Best For

The LONGi 605W Bifacial Solar Panel may be suitable for:

• Commercial solar installations requiring high module output.
• Industrial solar projects with suitable roof or ground space.
• Ground-mounted solar arrays designed to benefit from rear-side irradiance.
• Large rooftop systems where module dimensions and roof loading have been checked.
• Solar installers and project developers planning high-capacity PV arrays.

Final suitability depends on the available area, mounting arrangement, electrical limits and project requirements.

When Another Panel May Be Better

This panel may not be the best fit when:

• The available roof space cannot accommodate its large dimensions.
• The mounting structure cannot safely support the module’s weight and wind loading.
• The inverter’s maximum DC voltage or input-current limits do not suit the proposed string design.
• The installation arrangement prevents useful rear-side light from reaching the bifacial surface.
• The project requires a smaller module format for handling or layout reasons.

Check the complete system design before selecting panels based on wattage alone.

Cell and Module Technology

Bifacial Module Design

A bifacial panel can collect light from both sides. Its rear-side contribution is influenced by the surface below the module and the way the panels are installed. Light-coloured, reflective surfaces may provide more useful reflected light than darker surfaces, but the final energy gain must be assessed for the actual site.

132-Cell Configuration

The panel has 132 cells arranged in a 6 × 22 configuration. Its half-cell layout is designed to support module performance, and the construction incorporates three bypass diodes in the junction box.

Electrical Performance

The panel’s voltage and current values are important when determining how many modules can be connected in series and how many strings can be connected to an inverter. The rated wattage alone is not sufficient to establish compatibility.

Technical Specifications

Performance and Degradation

Long-term solar production depends on both the initial output and how the panel’s power capability changes over time.

The LONGi 605W Bifacial Solar Panel has a first-year power degradation specification of less than 1%. From the second through the thirtieth year, the specified annual degradation rate is 0.4%.

The 30-year performance warranty relates to linear power output and is separate from the product warranty. Buyers should distinguish between these two forms of coverage when evaluating the long-term value of a solar installation.

The panel’s temperature coefficient of -0.280%/°C for maximum power is also relevant in Pakistan’s hot climate. As the cell temperature rises above the standard reference temperature, power output generally decreases. Proper mounting ventilation can help limit excessive operating temperatures.

Performance Considerations for Pakistan

Pakistan’s solar installations can experience high summer temperatures, dust accumulation and changing sunlight conditions. These factors influence actual energy production.

For better system performance:

• Allow proper ventilation behind the panels to support heat dissipation.
• Clean the module surface when dust and soiling noticeably reduce light transmission.
• Plan bifacial mounting carefully to allow useful light to reach the rear surface.
• Check inverter compatibility using voltage, current and temperature-adjusted string calculations.
• Use a suitable mounting structure that accounts for the module’s dimensions, weight and site-specific wind conditions.

The 1500V maximum system voltage is a module limit, not a recommendation to operate every installation at that voltage. The installer must calculate string voltage under the site’s minimum expected temperature and follow the inverter and system-design limits.
