Hanersun 620W Bifacial Solar Panel

Hanersun 620W Bifacial Solar Panel Overview Overview

The Hanersun 620W Bifacial Solar Panel is designed for solar installations that need high power output from each module. It combines N-type TOPCon technology, monocrystalline cells and a bifacial design in a large-format panel measuring 2382 × 1134 mm.

With a rated power of 620W and an efficiency of 23.0%, this panel can help reduce the number of modules required for a given DC array capacity compared with lower-wattage panels, subject to the system design and available roof or ground space.

The bifacial construction allows the rear side to collect additional sunlight reflected from the installation surface. The amount of extra energy depends on factors such as ground reflectivity, mounting height, row spacing, shading and system layout. Actual energy production will also vary with sunlight, temperature, orientation and local installation conditions.

For customers comparing a Hanersun 620w bifacial solar panel price in Pakistan, it is important to consider rated power, efficiency, panel dimensions, installation requirements and warranty terms together.

Why Choose the Hanersun 620W Bifacial Solar Panel?

High 620W Power Output

The panel delivers 620W rated power under standard test conditions (STC). Its high wattage can help installers design larger solar arrays with fewer modules, depending on the required system capacity and available installation area.

N-Type TOPCon Technology

The panel uses N-type TOPCon monocrystalline cells. This cell technology supports high module efficiency, while the panel’s electrical design provides a rated module efficiency of 23.0%.

Bifacial Energy Collection

The bifacial design can collect sunlight from the front and rear sides. Rear-side contribution is not fixed; it depends on reflected sunlight and installation conditions. A suitable mounting structure and a surface that reflects sunlight can help improve the benefit of bifacial construction.

Low Power Temperature Coefficient

The maximum power temperature coefficient is -0.280%/°C. This indicates how module power changes with cell temperature relative to the reference temperature. It is a useful specification when assessing panel performance in warm climates such as Pakistan.

Designed for Outdoor Operation

The panel has a specified operating temperature range of -40°C to +85°C. Its construction includes 3.2 mm high-transmission, anti-reflective-coated, heat-strengthened glass and an anodized aluminium alloy frame.

Best For

The Hanersun 620W Bifacial Solar Panel may suit:

• Residential rooftop solar systems where the roof layout can accommodate its dimensions.
• Commercial and industrial solar installations requiring high-wattage modules.
• Ground-mounted solar arrays where rear-side light exposure can be considered in the design.
• Solar projects where installers need to assess panel efficiency, temperature behaviour and long-term output warranties.
• Buyers comparing hanersun 620w bifacial solar panel specifications before selecting modules for a new installation.

Final suitability depends on roof or mounting space, inverter input limits, string design, structural capacity and site conditions.

Important Installation Considerations

This is a large-format module measuring 2382 × 1134 × 30 mm and weighing 28.2 kg. Before ordering, confirm that the mounting structure, handling arrangements and installation area are suitable for its size and weight.

For bifacial performance, the rear side should have an appropriate installation arrangement. A mounting structure, roof surface or nearby obstruction that blocks reflected light may limit additional rear-side generation.

The solar installer should also verify the panel’s voltage and current ratings against the inverter’s operating limits, string configuration, maximum system voltage and applicable electrical design requirements.

Technical Specifications

STC: Irradiance 1000 W/m², cell temperature 25°C and AM1.5.

NMOT: Irradiance 800 W/m², ambient temperature 20°C and wind speed 1 m/s.

Understanding the Panel’s Bifacial Design

A bifacial solar panel can generate electricity from sunlight reaching both its front and rear sides. The front side receives direct sunlight, while the rear side can use reflected or scattered light from the surrounding surface.

The additional rear-side energy is influenced by the mounting height, surface reflectivity, row spacing, shading and site layout. Therefore, the actual energy gain varies from installation to installation.

The panel is identified as bifacial, but a numerical bifaciality percentage is not included in the available model specifications. No specific rear-side gain percentage should be assumed when estimating system production.

Recommended Solar System Planning

When planning a solar array with this 620W solar panel, the installer should calculate the required number of modules based on the desired DC capacity and then verify the final design against the inverter specifications.

For example, the total nominal DC array capacity can be calculated as:

Number of panels × 620W = Total nominal DC capacity

This is a basic capacity calculation, not a production forecast. Actual generation depends on sunlight, temperature, orientation, shading, losses and other site conditions.

Before installation, check the string’s total open-circuit voltage under the expected minimum temperature, operating voltage, current limits, inverter MPPT range and maximum permitted DC system voltage. The maximum system voltage of the panel must not be treated as the recommended operating voltage of an individual string.

Hanersun Solar Panels in Pakistan

When selecting a solar panel for a project in Pakistan, buyers should compare rated wattage, efficiency, dimensions, temperature coefficients and warranty terms. Installation conditions are especially important in warm weather, where module temperature can rise above ambient temperature.

The Hanersun 620W Bifacial Solar Panel offers a 620W rating, 23.0% module efficiency and a bifacial design. For a project that can make practical use of rear-side light, the mounting layout should be planned to support bifacial operation rather than relying on a fixed additional-generation estimate.

Customers searching for hanersun solar panel price in pakistan should also confirm the current selling price, availability and installation requirements before finalizing an order.
