The panel captures sunlight from both sides. Its front side receives direct sunlight, while the rear side can collect reflected light from the installation surface. However, the additional energy produced by the rear side depends on factors such as mounting height, tilt angle, ground reflectivity and the space behind the panel.

With 23.9% module efficiency, the panel offers a practical option for commercial rooftops, ground-mounted solar projects and other installations where available space and system output are important considerations. Therefore, it is worth evaluating for projects that require high rated power from each module.

Its low power temperature coefficient of -0.29%/°C is another useful feature for solar installations exposed to high summer temperatures. Nevertheless, correct mounting, ventilation, cleaning and electrical system design remain important for achieving good real-world performance.

Key Features and Benefits

N-Type TOPCon Cell Technology

The panel uses N-Type TOPCon cells designed for high module efficiency and controlled power degradation. This technology supports high-output solar installations where long-term energy production matters.

For buyers, the main advantage is the combination of rated power, efficiency and long-term power performance. However, actual energy production will still depend on sunlight, shading, temperature, orientation and system losses.

Bifacial Solar Generation

The bifacial construction allows the panel to receive sunlight from both the front and rear surfaces. Consequently, rear-side generation can increase total energy production when the mounting arrangement and surrounding surface allow reflected light to reach the back of the module.

The panel has 80% power bifaciality, with a ±5% tolerance. This is a measure of rear-side power capability relative to front-side power under standard test conditions. However, it is not a guaranteed percentage increase in the total energy produced by an installed system.

For better rear-side performance, installers should consider mounting height, tilt, row spacing and the reflectivity of the surface below the panels.

High Module Efficiency

The panel has a rated module efficiency of 23.9%. Higher efficiency helps produce more rated power from a given module area, which can be useful for commercial rooftops and installations with limited usable space.

Nevertheless, final system capacity depends on the number of modules, available area, inverter limits and the electrical design of the solar array.

Low Temperature Coefficient

The -0.29%/°C temperature coefficient for maximum power indicates how the panel’s maximum power changes as cell temperature rises above the reference temperature.

This characteristic is relevant in Pakistan, where modules can become considerably hotter than the surrounding air during summer. Therefore, adequate airflow beneath the panels and appropriate mounting arrangements help manage operating temperatures.

Durable Glass-to-Glass Construction

The panel uses 2.0 mm heat-strengthened glass on the front and rear, with an anodized aluminium alloy frame. In addition, its junction box carries an IP68 rating and includes three bypass diodes.

The module is designed for demanding outdoor solar installations. However, correct handling, suitable mounting hardware and compliance with installation requirements are necessary to protect the glass and electrical connections.

Best Applications for the Canadian 645W X20 Bifacial Solar Panel

The Canadian 645W X20 Bifacial Solar Panel is suitable for several types of solar projects, provided the installation meets the module’s electrical and mechanical requirements.

• Commercial rooftop solar systems: High module output can help achieve the planned system capacity.
• Ground-mounted solar installations: Suitable rear-side light exposure can improve bifacial energy generation.
• Residential solar projects: Appropriate for properties with sufficient roof space and a compatible electrical design.
• Industrial solar systems: Useful for installations requiring high-output modules.
• Solar installers and project developers: The 1500V maximum system voltage is relevant when designing compatible solar arrays.
• Long-term solar projects: The combination of bifacial generation and power performance coverage may suit projects focused on long-term energy production.

However, the final selection should consider inverter compatibility, mounting requirements and the available installation area.

When Another Solar Panel May Be More Suitable

This panel may not be the most practical choice for every installation.

• Small or restricted rooftops: Its large physical dimensions may make layout and handling more difficult.
• Limited rear-side light exposure: A bifacial module may deliver less additional rear-side energy when installed close to an opaque surface.
• Incompatible inverter inputs: The module’s voltage and current must fit the inverter’s operating range and input-current limits.
• Restricted handling access: Its dimensions and 32.8 kg weight require appropriate lifting, transport and installation arrangements.

Therefore, the correct panel selection should consider the complete system design rather than wattage alone.

Cell and Module Technology

The panel combines N-Type TOPCon cell technology with a bifacial, glass-to-glass module structure. Its 132-cell arrangement is configured as 2 × (11 × 6).

The front glass has an anti-reflective coating, while the rear uses heat-strengthened glass. As a result, the construction supports light collection from both sides and provides a rigid module structure for suitable mounting systems.

Bifacial performance also depends on the environment behind the panel. For example, light-coloured surfaces and appropriate clearance can improve reflected-light availability. Conversely, shading, dust and close mounting can reduce the additional energy captured from the rear.

Canadian 645W X20 Bifacial Solar Panel Specifications

The following Canadian 645W X20 Bifacial Solar Panel specifications cover its electrical ratings, construction, dimensions and warranty details.

Electrical ratings are based on Standard Test Conditions (STC), including 1000 W/m² irradiance, AM 1.5 spectrum and a cell temperature of 25°C. Therefore, electrical design should account for measurement tolerance and installation conditions.

Performance and Degradation

The panel includes a 30-year linear power performance warranty. Its specified first-year power degradation is no more than 1%, followed by annual degradation of no more than 0.4%.

These figures describe the panel’s stated power-degradation limits. However, they should not be interpreted as a guarantee of a particular electricity yield from a complete solar system.

Actual output varies with solar irradiance, shading, soiling, module temperature, orientation, cable losses, inverter performance and installation quality. Consequently, periodic inspection and appropriate cleaning help maintain energy production.

Performance Considerations for Pakistan

Pakistan’s high summer temperatures make temperature management important when planning a solar installation. The panel’s temperature coefficient helps buyers assess how heat affects its rated power, although it does not eliminate temperature-related losses.

For a well-designed installation:

• Provide suitable airflow beneath rooftop modules.
• Keep the panel surface clean while following safe cleaning practices.
• Avoid shading from nearby structures, trees and other modules.
• Design the mounting arrangement to allow useful rear-side light exposure.
• Check the inverter’s voltage and current limits before finalising the string layout.
• Use qualified installers and appropriate electrical protection.

Furthermore, the ground surface, mounting height and row spacing affect how much additional energy the rear side of a bifacial module can capture.
