Jinko 645W Bifacial Solar Panel

Jinko 645W Bifacial Solar Panel Overview

The Jinko 645W Bifacial Solar Panel combines high power output with N-Type TOPCon technology and a design that captures sunlight from both sides. As a result, it is suitable for solar projects where installers want strong output from each panel while making good use of the available space. If you want to know the Jinko 645W solar panel price in Pakistan, contact Hajvery Solar Energy for current pricing and purchase details.

Its 645W rated power and 23.88% module efficiency make it a useful option for commercial rooftops, industrial installations and ground-mounted solar systems. Moreover, its bifacial design allows the rear side to generate additional electricity when reflected or scattered sunlight reaches it.

However, the amount of extra energy depends on ground reflectivity, mounting height, row spacing, shading and overall system design. Therefore, buyers should consider these factors before estimating total energy production.

For solar installations in Pakistan, correct string sizing, secure mounting, suitable ventilation and regular cleaning are important. Together, these steps help support reliable solar generation.

Key Features and Benefits

N-Type TOPCon Cell Technology

This module uses N-Type monocrystalline TOPCon cells, which are designed to convert sunlight into electricity efficiently. Therefore, correct string design is important, especially when several high-wattage panels are connected to a solar inverter.

The 645W power rating can help installers use fewer panels to reach a target DC capacity compared with lower-wattage modules. However, the final number depends on available space and the electrical design.

Bifacial Energy Generation

The bifacial design allows the panel to capture sunlight from both sides. While the front side receives direct sunlight, the rear side can capture reflected and scattered light.

The panel has a bifaciality coefficient of 85% ± 5%. This figure describes the rear-side electrical performance under specified test conditions. However, it does not mean the complete solar system will automatically produce 85% more electricity.

Therefore, a suitable mounting layout, a reflective surface and less rear-side shading can help improve the benefits of bifacial technology.

High Module Efficiency

With 23.88% module efficiency, the panel converts a high share of the sunlight reaching its surface into electricity under standard test conditions.

As a result, it can be useful when installation space is limited. However, buyers should also consider roof dimensions, inverter limits, access pathways and mounting requirements before deciding how many panels to install.

Performance and Degradation

The module has a stated first-year degradation figure of 1% and annual degradation of 0.35% over the following performance period. In addition, its long-term power warranty provides a useful reference for assessing expected module output.

However, actual electricity production varies with sunlight, temperature, dust, shading, installation quality and system losses. For this reason, warranty figures should not be treated as a guarantee of the same electricity generation every year.

Durable Glass Construction

The panel features 2.0 mm anti-reflection-coated front glass, 2.0 mm heat-strengthened rear glass and an anodized aluminium alloy frame. It also has an IP68-rated junction box.

In addition, the module has a maximum static test load of 5400 Pa on the front side and 2400 Pa on the rear side. However, these test ratings do not replace a proper structural assessment or correct mounting procedures.

Best For

The Jinko 645W bifacial module can be considered for the following applications:

• Commercial solar systems that require high power output from each panel.
• Industrial rooftops with enough space and suitable structural support.
• Ground-mounted solar projects where the rear side can receive reflected sunlight.
• Large solar installations where panel count, array layout and electrical design need careful planning.
• Solar installers and dealers looking for a high-wattage bifacial panel for suitable projects.

However, final suitability depends on the inverter’s voltage and current limits, the mounting structure and the project’s energy requirements.

When Another Panel Configuration May Be Better

A different panel configuration may be more suitable if the roof cannot accommodate larger modules. Similarly, another option may be needed if the inverter cannot handle the panel’s electrical characteristics or the installation does not provide enough clearance for bifacial operation.

Before ordering, compare the panel dimensions with the available mounting area. Also, check its open-circuit voltage, operating voltage and current against the inverter’s limits. Therefore, do not choose a panel based on wattage alone.

Cell and Module Technology

The module combines N-Type monocrystalline TOPCon technology with a bifacial glass design. As a result, the front side converts sunlight into electricity while the rear side can also contribute when installation conditions are suitable.

The panel contains 264 half-cell positions arranged in a 66 × 4 configuration. Its electrical performance also depends on correct string configuration, suitable mounting and exposure to sunlight.

For bifacial installations, installers should consider the surface below the array, rear-side clearance, row spacing and possible shading. These factors help determine how much extra energy the rear side may generate.

Technical Specifications

The electrical values above are based on standard test conditions unless otherwise indicated. However, bifacial performance with additional rear-side sunlight is measured under separate test conditions.

Performance and Degradation

Long-term panel performance depends on the module’s electrical characteristics and the conditions in which it operates. The 12-year product warranty and 30-year linear power warranty cover different aspects of the product and its warranted power performance.

The stated first-year degradation is 1%, followed by an annual degradation figure of 0.35% over the following performance period. In addition, the stated warranted output at year 30 is 88.85%.

These figures describe warranted power performance, not the amount of electricity a solar system will generate each year. Actual output varies with sunlight, panel temperature, dust, shading, inverter performance and installation quality.

The temperature coefficient of Pmax is -0.26%/°C ± 5%. Therefore, this figure is useful when assessing how panel power changes as cell temperature rises above the standard test reference of 25°C.

Performance Considerations for Pakistan

Solar installations in Pakistan can experience high summer temperatures, dust and seasonal changes in sunlight. Therefore, correct system design and regular maintenance are important.

• Heat management: Provide suitable ventilation behind the panels to help limit heat build-up.
• Dust and cleaning: Inspect panels regularly and clean them when dust reduces output. Always follow safe cleaning practices.
• Bifacial installation: Allow enough space behind the panels and consider how reflective the mounting surface is.
• String design: Account for cold-weather open-circuit voltage, operating current and inverter input limits.
• Structural safety: Use mounting hardware and supports that suit the site’s wind conditions and structural requirements.

The panel’s operating temperature range is -40°C to +70°C. However, correct installation is still necessary to meet the applicable environmental and electrical limits.
