Jinko 620W Bifacial Solar Panel

Jinko 620W Bifacial Solar Panel Overview

The Jinko 620W Bifacial Solar Panel delivers a rated output of 620W, making it a practical choice for commercial rooftops, ground-mounted projects and larger solar systems. Moreover, its high power output helps installers use the available installation area efficiently. Before purchasing, check the Jinko 620w solar panel price in pakistan and confirm compatibility with your solar system.

The panel combines N-Type TOPCon cell technology with a dual-glass structure. In addition, its bifacial design captures sunlight from the rear side when the mounting arrangement, ground reflectivity and available clearance allow sufficient light to reach the back surface.

With 22.18% module efficiency, this panel delivers substantial rated power within its physical footprint. However, actual electricity generation depends on sunlight, temperature, shading, dust, orientation, installation quality and the overall system design.

For buyers in Pakistan, correct panel selection also requires checking the electrical characteristics against the inverter’s permitted voltage and current limits. Therefore, installers should verify compatibility before connecting the panel to the system.

Key Features and Benefits

N-Type TOPCon Cell Technology

The panel uses N-Type monocrystalline cells with TOPCon technology. This cell architecture helps reduce light-induced degradation and supports performance in lower-light conditions.

As a result, buyers can benefit from a combination of high power output and long-term performance potential. Nevertheless, actual daily production varies with sunlight and site conditions.

Bifacial Energy Generation

The bifacial solar panel generates electricity from both its front and rear surfaces. However, rear-side production depends on how much light reaches the back of the module and how effectively the surrounding surface reflects that light.

To improve rear-side energy capture, use a suitable mounting structure, adequate rear clearance and a reflective installation surface. Keep in mind that additional output varies by installation, so do not assume a fixed or guaranteed percentage.

620W Rated Power

The 620W rated output makes this panel suitable for projects that need substantial power from each module. Consequently, installers may need fewer panels to achieve a particular DC capacity compared with lower-wattage modules.

However, the final panel count depends on the target system size, inverter limits, available area and electrical string design.

Dual-Glass Construction

The module features 2.0 mm anti-reflection-coated front glass and 2.0 mm heat-strengthened rear glass. Together, these glass layers protect the cells and support the panel’s bifacial design.

Additionally, the anodized aluminium alloy frame provides structural support for the module.

Low Power Degradation

The panel has a stated degradation profile of 1% during the first year and 0.4% annually thereafter throughout the 30-year linear power warranty period.

Therefore, this degradation profile helps buyers assess long-term power retention. However, actual output still depends on operating conditions and the applicable warranty terms.

Enhanced Mechanical Load Resistance

The panel has a maximum static test load rating of 5400 Pa on the front side and 2400 Pa on the rear side. These ratings help installers assess the module’s mechanical requirements.

Even so, the mounting structure, clamps, spacing and installation method must meet the manufacturer’s installation requirements and the site’s conditions.

Best For

The Jinko 620W Bifacial Solar Panel suits several types of solar projects, including:

• Commercial solar installations that require high-output modules.
• Industrial solar projects with appropriate mounting and electrical design.
• Ground-mounted solar systems that provide suitable rear-side light exposure.
• Large rooftop installations with sufficient space and structural capacity.
• Solar installers and dealers looking for N-Type bifacial modules for suitable projects.

When Another Panel May Be Better

Although the Jinko 620W panel suits many installations, another panel may work better in certain situations.

• The roof or mounting area cannot accommodate the module’s dimensions.
• The inverter’s maximum input current or voltage limits do not match the panel’s electrical characteristics.
• The project requires a lighter or smaller module.
• The mounting design cannot provide suitable rear-side light exposure, while bifacial generation remains a major project requirement.

Ultimately, choose a panel according to the complete system design rather than wattage alone.

Cell and Module Technology

The Jinko 620W N-Type bifacial solar panel combines N-Type monocrystalline cells, TOPCon technology and dual-glass construction.

Its N-Type technology helps reduce light-induced degradation and supports low-light performance. Meanwhile, the bifacial structure allows the rear surface to contribute to electricity generation whenever sufficient light reaches it.

The panel contains 156 cells in a 78 × 2 configuration. Therefore, installers should use its 620W rating and electrical characteristics when calculating the solar array and checking compatibility with the selected inverter.

Technical Specifications

Performance and Degradation

The panel combines 620W rated output with 22.18% module efficiency. Together, these specifications help installers estimate the required panel count and approximate DC array capacity during system planning.

Furthermore, its power degradation profile supports long-term performance assessment. The panel has a stated first-year degradation of 1%, followed by annual degradation of 0.4% over the remaining linear power warranty period. Consequently, the stated warranted output reaches 87.4% of the initial rated power at year 30.

These figures provide performance benchmarks rather than a guarantee of the exact electricity an installation will generate. For example, dirt, shading, high operating temperatures and panel orientation can all affect actual energy production.

Performance Considerations for Pakistan

Solar panels in Pakistan face high summer temperatures, dust accumulation and changing sunlight conditions. Therefore, correct installation and regular maintenance play an important role in system performance.

• Heat management: Allow suitable airflow beneath the modules to help manage operating temperatures.
• Dust and cleaning: Dust reduces the light reaching the cells. Therefore, clean the modules using appropriate methods and follow the relevant safety guidance.
• Bifacial mounting: Rear-side output depends on mounting height, surface reflectivity, shading and available clearance. Consequently, assess these factors before choosing the mounting arrangement.
• Electrical design: Check the panel’s voltage and current against the inverter’s limits. In addition, account for low-temperature Voc when calculating string voltage and verifying the inverter’s maximum DC voltage.
• Mechanical support: Use a suitable mounting structure and installation method according to site conditions and expected loads.
