Yingli 705W Bifacial Solar Panel

Buy Yingli 705W Bifacial Solar Panel in Pakistan

The Yingli 705W Bifacial Solar Panel is a high-capacity solar module engineered for utility-scale, commercial and industrial solar installations. Built with advanced N-Type TOPCon cell technology, it delivers a rated front-side power output of 705 watts with a module efficiency of up to 22.7%.

As part of the Yingli PANDA 3.0 Plus 1 series, this module combines high wattage, bifacial power generation and durable dual-glass construction. Its positive power tolerance of 0 to +5W supports dependable rated performance under standard test conditions.

Advanced N-Type TOPCon Technology

The Yingli 705W solar panel uses N-Type monocrystalline silicon cells arranged in a 6 × 22 cell configuration. N-Type TOPCon technology supports high conversion efficiency, lower temperature-related power losses and stable long-term electricity generation.

The module features a power temperature coefficient of only -0.29% per °C, helping it maintain better performance as operating temperatures rise. This characteristic makes it suitable for large solar systems operating in Pakistan’s hot climate.

Up to 782W Bifacial Power Output

The bifacial dual-glass design allows the Yingli 705W panel to generate electricity from sunlight received on both its front and rear surfaces. Under the manufacturer’s BNPI bifacial test conditions, the panel can deliver power output of up to 782W.

Its bifacial performance includes:

• Front-side rated power output of 705W
• Bifacial power output of up to 782W
• Bifaciality coefficient of 80% ±5%
• Bifacial maximum power current of 19.20A
• Bifacial short-circuit current of 20.32A

Actual rear-side energy gain depends on ground reflectivity, mounting height, panel tilt, row spacing and overall system design.

High-Efficiency Electrical Performance

At Standard Test Conditions, the Yingli 705W Bifacial Solar Panel delivers:

• Maximum power voltage of 40.70V
• Maximum power current of 17.33A
• Open-circuit voltage of 48.30V
• Short-circuit current of 18.34A

The panel supports a maximum system voltage of 1500V DC and a maximum series fuse rating of 30A, making it suitable for professionally designed high-voltage solar arrays.

Reliable Performance Under Real Operating Conditions

Under Nominal Operating Cell Temperature conditions, the Yingli 705W module produces a power output of 536W. Its NOCT maximum power voltage is 38.83V, while the maximum operating current is 13.82A.

These NOCT values provide a useful reference for expected module performance under temperature and irradiance conditions that are closer to practical outdoor operation.

Durable Dual-Glass Construction

The Yingli 705W Bifacial Solar Panel features 2.0mm front glass and 2.0mm rear glass, supported by a robust anodized aluminium alloy frame. Its junction box includes three bypass diodes and carries an ingress protection rating of at least IP68.

The module is designed to withstand:

• Front static load of up to 5400 Pa
• Rear static load of up to 2400 Pa
• Hailstones measuring 25mm at a velocity of 23m/s
• Operating temperatures from -40°C to +85°C

It also carries a Class A fire-resistance rating, supporting safe installation in properly designed utility, commercial and industrial solar systems.

Enhanced Panel Size and Reduced BOS

With a rated power output of 705W, the module can help reduce the total number of panels required for a specified solar system capacity. Its enhanced panel size and high wattage may also reduce certain balance-of-system requirements, depending on project design.

The manufacturer identifies the Yingli PANDA 700W–720W series as ideal for utility projects.

Long-Term Manufacturer Warranty

The Yingli 705W Bifacial Solar Panel is supported by:

• 12-year product warranty
• 30-year power warranty
• 0.40% annual power degradation
• Approximately 87.4% guaranteed power output after 30 years

The warranty chart on page 1 of the datasheet shows the PANDA linear power warranty retaining 87.4% output at the end of year 30.
