Yingli 615W Bifacial Solar Panel

Buy Yingli 615W Bifacial Solar Panel in Pakistan

The Yingli 615W Bifacial Solar Panel is a high-performance photovoltaic module designed for utility-scale, commercial and industrial solar installations. Manufactured with advanced N-Type TOPCon cell technology, it delivers a rated front-side power output of 615 watts with module efficiency of up to 22.8%.

Part of the Yingli PANDA 3.0 Pro 2 series, this module combines high energy yield, bifacial power generation and robust dual-glass construction. Its positive power tolerance of 0 to +5W supports dependable rated output under standard test conditions.

Advanced N-Type TOPCon Technology

The Yingli 615W solar panel uses N-Type monocrystalline silicon cells arranged in a 6 × 22 cell configuration. N-Type TOPCon technology supports high power conversion, lower temperature-related losses and stable long-term solar energy generation.

The module features a low power temperature coefficient of -0.29% per °C, helping it retain better performance as operating temperatures rise. This characteristic makes it suitable for demanding solar projects in Pakistan’s hot climatic conditions.

Up to 682W Bifacial Power Output

The bifacial dual-glass design enables the Yingli 615W module to generate electricity from sunlight reaching both its front and rear surfaces. According to the manufacturer’s BNPI test conditions, this 615W panel can deliver bifacial power output of up to 682W.

Its bifacial performance includes:

• Front-side rated output of 615W
• Bifacial output of up to 682W
• Bifaciality coefficient of 80% ±5%
• Bifacial operating current of 16.49A
• Bifacial short-circuit current of 17.57A

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

High-Efficiency Electrical Performance

At Standard Test Conditions, the Yingli 615W Bifacial Solar Panel delivers:

• Maximum power voltage of 41.34V
• Maximum power current of 14.88A
• Open-circuit voltage of 49.31V
• Short-circuit current of 15.86A

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 615W panel produces a rated power output of 468W. Its NOCT operating voltage is 39.44V, while the maximum operating current is 11.86A.

These figures provide a practical reference for module performance under operating conditions that are closer to real-world temperatures and irradiance levels than standard laboratory testing.

Durable Dual-Glass Construction

The Yingli 615W solar panel uses 2.0mm front glass and 2.0mm rear glass, supported by a strong anodized aluminium alloy frame. Its junction box contains three bypass diodes and has an ingress protection rating of at least IP68.

The module is engineered 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 use in suitable rooftop and ground-mounted projects.

Built for High Energy Yield

The Yingli PANDA 3.0 Pro 2 series is designed around outstanding bifaciality, superior energy yield and a robust frame. With a rated output of 615W and 22.8% module efficiency, the panel can produce substantial power from the available installation area.

The manufacturer identifies this module series as ideal for utility projects, while its electrical and mechanical characteristics also support properly engineered commercial and industrial solar systems.
