LONGi 580W Bifacial Solar Panel

LONGi 580W Bifacial Solar Panel Overview

The LONGi 580W Bifacial Solar Panel combines high rated power, bifacial energy generation and dual-glass construction. Its exact model is LR5-72HGD-580M, part of the Hi-MO 7 series. With 580W rated output and 22.5% module efficiency, it can help solar project designers make effective use of the available installation area.

This module can be considered for commercial rooftops, industrial solar systems and suitable ground-mounted installations. Before selecting it, buyers should consider module dimensions, inverter compatibility, string voltage, current limits, mounting requirements and operating conditions.

Buyers researching LONGi 580W Bifacial solar panel price in pakistan should compare the exact model, electrical ratings, warranty coverage and installation requirements rather than relying on wattage alone.

Key Features and Benefits

580W Rated Power

The module provides 580W rated power under Standard Test Conditions (STC). Higher output per module can reduce the number of modules required for a target array capacity compared with lower-output modules, depending on the project design. The final module count must be calculated according to system capacity and electrical limits.

Bifacial Energy Generation

The bifacial design allows the module to receive sunlight from both the front and rear sides. The additional energy generated from the rear depends on ground reflectivity, mounting height, shading, rear-side clearance and the surrounding installation environment.

The module has a stated bifaciality of 80 ± 5%. This figure should not be treated as a guaranteed percentage increase in total system energy. Actual bifacial gain varies with site conditions.

22.5% Module Efficiency

With 22.5% module efficiency, the panel converts a proportion of the sunlight reaching its surface into electrical power under standard test conditions. This can be useful where installation space is limited. The final layout must also allow for panel dimensions, mounting clearances, access routes and shading.

Dual-Glass Construction

The panel uses 2.0 mm + 2.0 mm heat-strengthened glass and an anodized aluminium-alloy frame. Its mounting structure, clamps and installation method must be suitable for the module dimensions and mechanical loading requirements.

Low Power Degradation

The stated first-year power degradation is less than 1%, followed by 0.4% annual degradation from years 2 to 30. The 30-year extra linear power output warranty profile indicates 87.4% output at year 30.

Actual energy production also depends on installation quality, shading, soiling, temperature and other operating conditions.

Best For

The LONGi 580W Bifacial Solar Panel may suit:

• Commercial and industrial solar installations.
• Ground-mounted solar systems designed to benefit from rear-side sunlight.
• Projects where higher output per module is useful.
• Installations that can accommodate the panel’s 2278 × 1134 mm dimensions.
• Solar projects requiring a long-term performance warranty.

When Another Panel May Be Better

A different solar module may be more suitable if the available mounting area cannot accommodate this panel’s dimensions, the inverter’s voltage or current limits are incompatible, or the project specifically requires a monofacial module.

Before installation, check the string configuration, temperature-adjusted open-circuit voltage, short-circuit current limits and the system’s maximum permitted voltage.

Cell and Module Technology

The Hi-MO 7 family uses HPDC cell technology. This 580W variant has a 144-cell configuration arranged as 6 × 24 cells and a bifacial dual-glass structure.

Its key electrical characteristics under Standard Test Conditions include:

• Maximum Power (Pmax): 580W
• Voltage at Maximum Power (Vmp): 43.22V
• Current at Maximum Power (Imp): 13.42A
• Open-Circuit Voltage (Voc): 51.41V
• Short-Circuit Current (Isc): 14.22A

These values help installers design suitable strings. The final design must account for inverter limits, minimum site temperature and applicable electrical requirements.

Technical Specifications

Performance and Degradation

The panel’s −0.280%/°C maximum power temperature coefficient describes how its output changes as cell temperature rises above the reference temperature. In Pakistan’s hot summers, proper mounting ventilation and suitable system design are important because module temperature can rise significantly above ambient air temperature.

The stated degradation profile is less than 1% in the first year and 0.4% annually during years 2–30. The performance warranty profile indicates 87.4% output at year 30. These figures describe the module’s stated performance profile and do not guarantee the annual energy production of a complete solar system.

Performance Considerations for Pakistan

Dust, high module temperatures, shading and poor ventilation can affect real-world energy generation. Keep the module surface clean using appropriate methods, allow suitable airflow beneath the panels and ensure that the mounting structure is correctly designed.

For bifacial solar panels, the rear side needs suitable exposure to reflected sunlight. Mounting height, ground surface and shading can influence additional energy generation. An installer should also verify panel voltage and current against the selected inverter and planned string configuration.
