Yingli 720W Bifacial Solar Panel

Buy Yingli 720W Bifacial Solar Panel in Pakistan

The Yingli 720W Bifacial Solar Panel is a high-capacity photovoltaic module engineered for utility-scale and large solar energy projects. Built with advanced N-Type TOPCon technology, the module delivers a rated front-side power output of 720 watts with an impressive module efficiency of up to 23.2%.

Its bifacial dual-glass design generates electricity from both the front and rear sides of the module. Under the manufacturer’s BNPI bifacial test conditions, the Yingli 720W panel can produce up to 798W, providing greater energy-generation potential when installed over suitable reflective surfaces.

Advanced N-Type TOPCon Cell Technology

The Yingli 720W solar panel uses N-Type monocrystalline silicon cells in a 6 × 22 cell configuration. N-Type TOPCon technology supports high conversion efficiency, strong performance under changing operating conditions and reliable long-term energy production.

The module features a low power temperature coefficient of -0.29% per °C, helping reduce temperature-related output losses during hot operating conditions.

Up to 798W Bifacial Power Output

The Yingli 720W Bifacial Solar Panel captures direct sunlight from the front and reflected sunlight through its rear surface. According to the datasheet’s bifacial test conditions, the 720W module provides:

• Front-side rated output of 720W
• Bifacial power output of up to 798W
• Bifaciality coefficient of 80% ±5%
• Bifacial operating current of 19.39A
• Bifacial short-circuit current of 20.45A

Actual bifacial gain depends on ground reflectivity, panel mounting height, row spacing, tilt angle and overall system design.

High-Efficiency Performance

At Standard Test Conditions, the Yingli 720W panel delivers a maximum power voltage of 41.15V and a maximum power current of 17.50A. Its positive power tolerance of 0 to +5W means the module is manufactured within a positive output tolerance range.

The module supports a maximum system voltage of 1500V DC, making it suitable for professionally designed high-voltage solar arrays.

Durable Dual-Glass Construction

The module uses 2.0mm front glass and 2.0mm rear glass, combined with an anodized aluminium alloy frame. Its junction box includes three bypass diodes and carries an ingress protection rating of at least IP68.

The panel 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.

Enhanced Panel Size and Reduced BOS

The Yingli 720W Bifacial Solar Panel is designed with enhanced module dimensions and high wattage to support utility-scale solar installations. Its larger power capacity can help reduce the number of modules required for a specified system capacity, supporting reduced balance-of-system requirements where the project design permits.

The manufacturer identifies this module series as ideal for utility projects.

Long-Term Manufacturer Warranty

The Yingli 720W Bifacial Solar Panel is supported by:

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

The warranty graph shown in the datasheet indicates approximately 99% retained output after the first year and 87.4% at the end of year 30.
