Ronma 620W Bifacial Solar Panel

Ronma 620W Bifacial Solar Panel Overview

The Ronma 620W Bifacial Solar Panel suits solar projects that require high power output from each installed module. Its N-Type TOPCon cell technology and bifacial construction make it a practical option for installations where energy production, available mounting space and long-term performance matter.

The panel delivers a rated output of 620W and a conversion efficiency of 23%. Furthermore, its bifacial design allows the rear surface to contribute to electricity generation when sunlight reaches it. However, the additional energy varies with the installation surface, panel height, ground reflectivity, shading and mounting configuration.

For solar installers and project planners in Pakistan, the panel’s electrical characteristics play an important role in string design and inverter selection. Therefore, installers should check the maximum system voltage, operating voltage and current ratings before installation.

Key Features and Benefits

N-Type TOPCon Cell Technology

The module uses N-Type TOPCon monocrystalline cells, which support efficient solar energy conversion. In addition, the 620W rated output provides substantial nominal power from each panel.

This combination can help project designers balance module power, array size and available installation space. However, the final design must also account for the inverter’s electrical limits and the site’s operating conditions.

Bifacial Solar Generation

A bifacial solar panel can generate electricity from both its front and rear surfaces. The amount of rear-side generation depends on the mounting arrangement and the direct or reflected sunlight reaching the back.

For example, ground-mounted installations can benefit from suitable panel clearance and a reflective surface beneath the modules. On the other hand, rooftop structures and darker roof surfaces may limit rear-side generation. Consequently, buyers should assess the installation conditions instead of assuming a fixed percentage of additional energy.

620W Rated Power

The panel delivers a nominal power output of 620 watts under standard test conditions. Moreover, higher wattage per module can reduce the number of panels required to achieve a target array capacity, provided the electrical design and available space allow it.

Actual energy production, however, varies with sunlight, temperature, orientation, shading, dust and system losses. For this reason, installers should evaluate the complete system rather than relying on wattage alone.

1500V DC System Rating

The module supports a maximum system voltage of 1500V DC. This rating is particularly relevant when installers design solar arrays and strings for larger projects.

Nevertheless, this rating does not guarantee compatibility with every inverter or string configuration. Installers must calculate the temperature-adjusted open-circuit voltage and check the selected inverter’s DC voltage and current limits before connecting the panels.

Durable Module Construction

The module measures 2382 × 1134 × 30 mm. Therefore, installers should account for these dimensions when planning mounting rails, panel spacing, transportation and installation access.

Additionally, correct handling, secure mounting, appropriate earthing and compliance with applicable installation requirements help support long-term system reliability.

Best For

The Ronma 620W Bifacial Solar Panel can suit the following applications:

• Commercial solar installations that require high-output modules.
• Ground-mounted solar projects where the rear surface can receive reflected sunlight.
• Industrial solar systems with compatible module voltage and current ratings.
• Large solar arrays where installers must carefully plan panel quantities, mounting space and string configurations.
• Solar installers and EPC contractors seeking N-Type TOPCon bifacial modules for suitable projects.

Ultimately, the panel’s suitability depends on the inverter, mounting system, site conditions and complete array design.

When Another Panel May Be Better

Although the Ronma 620W Bifacial Solar Panel suits many high-output projects, another module may be more appropriate in certain situations.

• The available roof or mounting area cannot accommodate its dimensions.
• The inverter’s maximum input current or short-circuit current limit does not support the module’s electrical characteristics.
• The project requires a different voltage or string configuration.
• The installation surface provides little useful rear-side light, while the project’s financial calculations depend on substantial bifacial gains.

Therefore, buyers should compare the full electrical specifications and installation requirements before selecting a panel. Choosing solely on the basis of wattage may lead to an unsuitable system design.

Cell and Module Technology

N-Type TOPCon

TOPCon stands for Tunnel Oxide Passivated Contact. It is a solar cell architecture designed to improve the efficiency of converting sunlight into electricity. The Ronma module combines N-Type TOPCon cells with a monocrystalline structure.

As a result, this technology provides a useful basis for high-output solar installations. However, actual system performance still depends on operating conditions and correct installation.

Bifacial Monocrystalline Design

The panel uses a bifacial design to capture light reaching both its front and rear surfaces. Consequently, the rear side can contribute additional electricity when the installation allows sufficient light to reach it.

The amount of rear-side contribution varies with the environment. For this reason, project planners should assess ground reflectivity, mounting height, spacing and shading before estimating additional generation.

132-Cell Configuration

The module contains 132 cells. Along with its dimensions and electrical characteristics, this cell configuration helps installers plan the physical layout and electrical arrangement of the solar array.

Technical Specifications

Performance and Degradation

The Ronma 620W Bifacial Solar Panel offers a 23% module efficiency under standard test conditions. This figure indicates how effectively the module converts sunlight falling on its surface into electrical power under defined testing conditions. In actual installations, however, environmental conditions and system design influence the final energy yield.

The panel has a maximum-power temperature coefficient of -0.30%/°C. In practical terms, its output power decreases as cell temperature rises above the reference temperature, all else being equal. Therefore, adequate mounting ventilation and correct installation can help manage operating temperatures during Pakistan’s hot summers.

The module also carries a 30-year linear performance warranty. Buyers should review the applicable performance warranty terms alongside the separate product warranty to understand the coverage provided.

Performance Considerations for Pakistan

High Summer Temperatures

Solar modules can operate at temperatures above the surrounding air temperature when exposed to direct sunlight. Consequently, the panel’s temperature coefficient matters when estimating output during hot weather.

Actual power losses depend on cell temperature, wind, mounting arrangement and site conditions. For this reason, installers should consider ventilation and suitable mounting practices when designing solar systems for Pakistan.

Dust and Cleaning

Dust and other deposits reduce the sunlight reaching solar cells. Therefore, an appropriate cleaning schedule can help maintain energy production, particularly in areas with frequent dust.

However, cleaning must follow safe procedures. Avoid damaging the glass or module surface, and use suitable methods for the installation environment.

Bifacial Installation

Rear-side generation depends on the amount of sunlight reaching the back of the panel. Accordingly, installers should consider ground reflectivity, panel elevation, spacing and shading when designing a bifacial installation.

A suitable mounting arrangement can improve the opportunity for rear-side generation. Nevertheless, the actual gain varies from one site to another.

Electrical Design

The panel’s Voc, Vmp, Isc and Imp must match the selected inverter’s input requirements. In particular, installers should account for the expected minimum cell temperature when calculating string voltage.

Similarly, the array current must remain within the inverter’s operating and short-circuit input limits. Therefore, a qualified installer should verify the complete string configuration before connecting the modules.
