Description

Jinko 640W Bifacial Solar Panel Overview

Its N-Type monocrystalline cells provide a rated output of 640W under standard test conditions. Want to know the Jinko 640w solar panel price in pakistan? Contact Hajvery Solar Energy for the latest price and availability.

The panel uses a bifacial dual-glass design, allowing the rear side to contribute additional electricity when sunlight reflects from suitable ground or surrounding surfaces. Actual rear-side generation depends on installation height, surface reflectivity, shading and system design.

Its SMBB technology supports improved light trapping and current collection, while Hot 2.0 technology is designed to improve reliability and reduce light-induced and elevated-temperature-induced degradation. These features make the module worth considering for commercial rooftops, ground-mounted arrays and larger solar installations.

Key Features and Benefits

N-Type Monocrystalline Technology

The N-Type cell design provides a rated module efficiency of 22.90%. Higher module efficiency can help produce more rated power from a given panel area, which is useful when available installation space is limited.

Bifacial Energy Generation

The bifacial design captures sunlight from the front and rear surfaces. A suitable mounting arrangement with adequate rear-side light exposure can increase total energy generation compared with front-side output alone.

The additional yield is not fixed. Ground colour, mounting height, tilt, row spacing, nearby obstructions and sunlight conditions all affect rear-side performance.

Dual-Glass Construction

The module uses 2.0 mm anti-reflective front glass and 2.0 mm heat-strengthened rear glass. This construction is suitable for projects that require a glass-glass module design.

SMBB and Hot 2.0 Technologies

SMBB technology improves light trapping and current collection. Hot 2.0 technology is intended to improve reliability and reduce LID/LETID-related degradation.

Mechanical Load Resistance

The module is certified for a 2400 Pa wind load and a 5400 Pa snow load. Correct mounting hardware, support spacing and installation practices remain essential for meeting site requirements.

Best For

The Jinko 640W bifacial panel may suit:

  • Commercial solar systems requiring high-output modules.
  • Industrial rooftops with sufficient space and suitable structural capacity.
  • Ground-mounted solar installations where rear-side light exposure can be improved.
  • Residential systems where panel dimensions and electrical characteristics suit the available roof.
  • Solar installers and dealers designing systems around high-wattage bifacial modules.

When Another Panel May Be Better

Consider a different module if the installation requires smaller panel dimensions, has strict current or voltage limits, or cannot accommodate the size and weight of this panel.

A monofacial design may also be worth considering where rear-side light exposure is very limited. The final selection should be based on the complete system design rather than wattage alone.

Cell and Module Technology

The module combines N-Type monocrystalline cells, bifacial energy generation and dual-glass construction. Its 156-cell layout uses a 2 × 78 arrangement.

The combination of front-side power production and potential rear-side gain can be useful for projects designed to make effective use of reflected sunlight. However, the bifacial design does not guarantee a particular percentage increase in annual electricity production.

Bifacial Output and Rear-Side Gain

Rear-side contribution can increase the module’s combined output under suitable test or installation conditions. The following figures are illustrative performance points for this 640W model, not guaranteed field output.

Rear-Side Power Gain Combined Power Combined Module Efficiency
5% 672W 24.05%
15% 736W 26.34%
25% 800W 28.63%

Actual results depend on rear-side irradiance and the installation environment. System designers should not use these figures as a guaranteed daily or annual energy yield.

Performance and Degradation

The module has a -0.29%/°C Pmax temperature coefficient. This describes how maximum power changes as cell temperature moves above or below the reference temperature. Actual output also depends on sunlight intensity, mounting, ventilation, shading and other system conditions.

The linear power warranty extends for 30 years, with an indicated annual degradation rate of 0.40% and 87.4% guaranteed power performance at year 30. The separate product warranty covers 12 years. Applicable warranty terms and conditions should be checked before purchase.

Performance Considerations for Pakistan

Pakistan’s summer temperatures make suitable mounting and ventilation important. Leave adequate space beneath the panels for airflow, use an installation structure designed for the site’s wind conditions and account for dust accumulation when planning cleaning.

For bifacial installations, rear-side clearance and the reflectivity of the surface beneath the panels can influence additional generation. Installers should also consider module voltage and current when designing strings, particularly when several panels are connected in series.

The panel’s dimensions, weight and electrical limits must be compatible with the roof structure, mounting system and selected inverter.

Hajvery Solar Product Verification

Before ordering, confirm the exact model number JKM640N-78HL4-BDV, panel condition, serial information and applicable warranty. The model identity is important because panels with similar wattage may have different electrical characteristics.

For system planning, match the panel’s open-circuit voltage, operating voltage, short-circuit current and operating current to the inverter’s permitted PV input limits. String calculations should account for temperature-related voltage changes and the inverter’s maximum input current.

Hajvery Solar Energy serves buyers in Lahore and across Pakistan. Customers can discuss panel selection and system requirements before placing an order.
