LONGi 585W Bifacial Solar Panel Overview

The LONGi 585W Bifacial Solar Panel combines high power output, bifacial energy generation and a durable dual-glass design. Part of the Hi-MO 7 series, this module uses HPDC cell technology to deliver high power and module efficiency for large solar installations.

With a rated output of 585 watts and module efficiency of 22.6%, it helps solar project designers make effective use of available installation space. Its bifacial construction allows the rear side to capture reflected sunlight, depending on mounting height, ground surface, spacing and surrounding conditions.

The panel features 144 half-cut cells, heat-strengthened glass on both sides and an anodised aluminium alloy frame. These construction features are relevant for projects where long-term power output, mechanical strength and efficient energy generation are important.

For buyers comparing the LONGi 585W Bifacial solar panel price in pakistan, it is important to consider the panel’s electrical specifications, installation requirements, inverter compatibility and warranty coverage alongside its rated wattage.

Key Features and Benefits

1. 585W High Power Output

With a rated power output of 585W, this solar module can contribute substantial capacity to a properly designed solar array. Installers can calculate the required number of panels according to the target system capacity, available space and inverter limits.

Actual electricity production depends on sunlight, temperature, shading, dust accumulation, panel orientation and overall system design.

2. Bifacial Energy Generation

The bifacial design allows the panel to generate electricity from both its front and rear sides. Its 80 ± 5% bifaciality indicates the rear-side power capability relative to the front-side reference under the relevant test conditions.

Actual rear-side energy gain varies with installation conditions. A reflective ground surface, suitable mounting clearance and reduced rear-side shading can help increase the contribution from reflected sunlight.

3. HPDC Cell Technology

The Hi-MO 7 series uses HPDC cell technology to support high module power and efficiency. The 585W version achieves 22.6% module efficiency, helping convert available sunlight into electrical power within the module’s surface area.

This makes the panel relevant for solar projects where both rated output and efficient use of installation space matter.

4. Dual-Glass Construction

The panel features 2.0 + 2.0 mm heat-strengthened glass and an anodised aluminium alloy frame. Its dual-glass construction provides a protective structure for the solar cells and supports long-term use in appropriately engineered solar installations.

5. Low Power Degradation

The module has a first-year power degradation rating of less than 1%, followed by 0.4% annual degradation from years 2 to 30 under its stated performance warranty framework.

These ratings help buyers assess long-term power retention. Actual electricity generation may vary with environmental conditions, installation quality and maintenance.

Best For

The LONGi 585W Bifacial Solar Panel may be suitable for:

• Commercial solar installations requiring high-output modules.
• Utility-scale solar projects designed around bifacial technology.
• Ground-mounted solar systems with suitable rear-side clearance.
• Solar installations where 22.6% module efficiency is important for space planning.
• Installers and project developers designing systems around verified electrical limits.
• Projects where the mounting arrangement can make effective use of rear-side solar generation.

When Another Panel May Be Better

This panel may not be the most suitable choice when:

• The available mounting space cannot accommodate its dimensions.
• The inverter cannot accept the panel’s voltage or current characteristics.
• The installation requires a different module size or mounting configuration.
• The project cannot provide suitable rear-side light exposure and relies heavily on additional bifacial generation.
• The electrical requirements of the existing solar system do not match the panel’s specifications.

Before purchasing, confirm the panel dimensions, mounting arrangement and electrical compatibility with the installer.

Cell and Module Technology

The LONGi Hi-MO 7 585W Solar Panel uses HPDC cell technology and a bifacial, dual-glass module structure. Its 144 half-cut cells are arranged in a 6 × 24 configuration.

Half-cell construction divides the cells into smaller sections, while bifacial construction enables the rear side to contribute to energy production when reflected sunlight reaches the module.

The combination of high rated power, bifacial capability and dual-glass construction makes this module relevant for projects seeking high output and long-term power retention.

Technical Specifications

Performance and Degradation

The LONGi 585W Bifacial Solar Panel has a first-year power degradation rating of less than 1%, followed by a stated annual degradation rate of 0.4% for years 2–30.

Its long-term performance warranty framework indicates a warranted power output of 87.4% at year 30. This figure relates to power retention rather than a guarantee of annual electricity generation.

The panel’s temperature coefficient of maximum power is -0.280%/°C. As the module temperature rises above the standard test reference, its power output generally decreases. Appropriate mounting clearance and ventilation can help manage operating temperatures.

Actual energy production depends on sunlight availability, temperature, shading, dust and the design of the complete solar system.

Performance Considerations for Pakistan

Pakistan’s hot summers, dust and seasonal sunlight variations make correct solar system design important. The following factors should be considered when installing the LONGi 585W Bifacial Solar Panel.

Temperature: Account for the reduction in module power at higher operating temperatures.

Dust and Cleaning: Dust accumulation can reduce the sunlight reaching the solar cells. An appropriate cleaning schedule can help maintain energy production.

Rear-Side Clearance: Avoid unnecessarily blocking the rear surface when bifacial energy generation is an important part of the project.

Ground Reflectivity: The surface beneath a ground-mounted solar array affects how much reflected sunlight reaches the rear side.

String Design: Check voltage and current limits against the selected inverter, including temperature-adjusted open-circuit voltage.

Mounting and Protection: Use suitable mounting hardware, earthing and electrical protection for the installation.

A qualified installer should verify the complete system design before installation.
