Cora Dawn 645W Bifacial Solar Panel

Cora Dawn 645W Bifacial Solar Panel Overview

The Cora Dawn 645W Bifacial Solar Panel is designed for solar installations that require high power output per module. Its 645W rated capacity helps reduce the number of panels needed for a given DC capacity compared with lower-wattage modules, subject to the electrical and physical requirements of the project. For buyers interested in the Cora Dawn 645W solar panel price in pakistan, the bifacial design can also provide additional energy generation when suitable mounting and reflected-light conditions are available.

Moreover, this panel combines N-Type BC cell technology, bifacial energy generation and a dual-glass structure. Its rear side can contribute to electricity production when reflected sunlight reaches the cells. However, the actual gain depends on mounting height, ground reflectivity, row spacing, shading and other site conditions.

With 23.9% module efficiency, the panel suits projects where available installation area and module output are important considerations. For example, buyers can evaluate it for residential rooftops, commercial buildings and ground-mounted solar systems, provided its dimensions, electrical characteristics and mounting requirements suit the installation.

Key Features and Benefits

645W High Power Output

The panel delivers a rated power output of 645W under standard test conditions (STC). As a result, high-wattage modules can help installers achieve a planned solar array capacity with fewer panels, although the final panel count depends on the required system size and inverter limits.

In addition, its STC electrical values include a maximum power voltage of 45.20V and a maximum power current of 14.27A. These values help installers assess string configuration and inverter compatibility.

N-Type BC Cell Technology

The module uses N-Type BC (Back Contact) cells. This cell architecture positions electrical contacts at the rear of the cells, helping reduce front-side shading from conventional front contact patterns.

Therefore, buyers should consider the module’s rated output, conversion efficiency, degradation profile and compatibility with the complete solar system before making a decision.

Bifacial Energy Generation

The bifacial design enables the rear side of the panel to contribute to energy generation when reflected light reaches it. Furthermore, the panel has a bifacial factor of 70% ± 5%.

However, actual rear-side generation does not represent a fixed percentage of the front-side output. Instead, it varies with the surface below the panels, mounting structure, installation height, spacing, surrounding obstructions and sunlight conditions. Consequently, a suitable mounting design can help make better use of the panel’s bifacial capability.

23.9% Module Efficiency

The 23.9% module efficiency allows the panel to deliver a relatively high rated output from its surface area. This feature is particularly useful when designing rooftop and commercial installations where usable space is limited.

Nevertheless, actual daily and annual energy production depends on sunlight, module temperature, shading, dust, orientation, tilt, inverter performance and installation quality.

Dual-Glass Construction

The panel features 2.0mm + 2.0mm coated semi-tempered glass. This dual-glass construction supports the module’s bifacial design and provides a glass-based structure on both sides.

However, correct handling remains essential for long-term use. Installers should also use suitable mounting clamps and follow the applicable installation requirements.

Long-Term Power Performance

The panel carries a 30-year linear power output warranty. Its stated first-year power attenuation is no more than 1%, while annual power attenuation from years 2 through 30 is no more than 0.35%.

These figures describe the warranted performance profile. However, they do not guarantee the actual electricity generated by a complete solar system, since real-world output also depends on environmental and installation conditions.

Best For

The Cora Dawn 645W Bifacial Solar Panel can suit several types of solar installations, depending on the project requirements:

• Residential solar systems: Suitable where roof area, panel dimensions and inverter limits allow installation.
• Commercial rooftop projects: A useful option for installations requiring substantial DC capacity.
• Ground-mounted solar installations: Suitable where the rear side can receive reflected sunlight.
• Industrial solar projects: An option for sites with suitable structural support and electrical design.
• Solar installers and dealers: Worth considering when selecting high-wattage bifacial modules.
• Projects with limited installation space: Useful where the module dimensions and handling requirements fit the available area.

Nevertheless, final selection should account for the project’s required capacity, inverter compatibility, mounting design and expected site conditions.

When Another Panel May Be Better

Although this panel offers a high rated output, it may not suit every installation. Therefore, consider the following points before ordering:

• Restricted roof dimensions: Its physical size may not suit smaller or irregular roof sections.
• Inverter current limits: Installers must check the maximum power current and short-circuit current against the inverter’s per-MPPT and per-string limits.
• Low rear-side light exposure: A bifacial module may deliver limited additional rear-side energy when installed close to an opaque surface or where the rear side receives heavy shading.
• Different system voltage requirements: The string design must remain within the inverter’s permitted voltage and current limits.
• Handling and structural constraints: The mounting structure must support the module’s dimensions, weight and applicable installation loads.

Ultimately, a technically suitable panel matters more than wattage alone. Therefore, confirm the complete electrical design before finalising the purchase.

Cell and Module Technology

The Cora Dawn 645W module combines N-Type BC cells with a bifacial, dual-glass construction.

Its rated power output is 645W under STC. Meanwhile, its bifacial capability allows reflected sunlight to contribute to production under suitable conditions. The panel also uses 144 cells arranged in a 6 × 24 configuration.

For effective solar array design, installers should consider the module’s 23.9% efficiency alongside its electrical characteristics. In addition, the cell technology and bifacial design do not eliminate the need for correct orientation, string calculations, structural support and suitable inverter selection.

Technical Specifications

Performance and Degradation

The panel has a stated first-year power attenuation of no more than 1%. Furthermore, annual power attenuation remains within the stated limit of 0.35% from the second year through year 30.

The long-term performance warranty specifies 88.85% of initial power output at year 30. However, these figures describe the product’s linear power warranty profile rather than guaranteed annual electricity generation.

In practice, actual system production depends on local sunlight, module temperature, dust accumulation, shading, installation angle, wiring, inverter efficiency and maintenance.

Therefore, regular cleaning when needed and correct mounting can help maintain system performance. Buyers should also check the applicable warranty terms and conditions before purchasing.

Performance Considerations for Pakistan

Solar installations in Pakistan experience seasonal changes in sunlight, high summer temperatures and dust accumulation. Consequently, these factors can affect energy production even when a panel has a high rated output.

The Cora Dawn 645W panel has a Pmax temperature coefficient of -0.26%/°C. Since module temperature can rise above ambient temperature under strong sunlight, installers should account for temperature effects when estimating performance.

For bifacial installations, the surface beneath the panel also matters. For example, a suitable ground surface, sufficient rear clearance and reduced rear-side shading can improve the opportunity for additional generation.

Buyers should also consider the following installation and maintenance practices:

• Regular inspection and cleaning: Adjust cleaning frequency to local dust conditions.
• Adequate airflow: Allow suitable ventilation around rooftop-mounted modules.
• Correct orientation: Choose an appropriate tilt, orientation and row spacing.
• Secure mounting: Select a structure that suits the roof or ground installation.
• Accurate string sizing: Check inverter voltage and current limits before installation.
• Electrical protection: Use suitable earthing, wiring and protection equipment.

Ultimately, no panel can guarantee the same output throughout the year. Therefore, site-specific system design provides a more realistic basis for estimating energy production.
