Model Bi-11-380 | Mono PERC Bifacial | 72 Full Cells Monocrystalline | Bifacial | 1500V System Voltage
The Waaree Energies Bi-11-380 380W Mono PERC bifacial solar panel is a high performance dual glass module designed for reliable long term energy generation in demanding Indian and global conditions. This 380 watt solar panel delivers strong output with a front side efficiency of 19.02 percent, while bifacial technology unlocks additional backside power gain on reflective surfaces for higher system yields. The module uses advanced monocrystalline PERC cells in a 72 cell configuration, combined with dual tempered glass and an anti reflection coating for better light transmission and enhanced durability against sand, hail, wind and snow loads. Engineered around a 1500 volt system voltage and a 25 amp series fuse rating, the Bi-11-380 integrates smoothly into modern residential, commercial and industrial rooftop arrays as well as ground mounted projects. Customers benefit from a 10 year product warranty and a linear performance warranty that guarantees 90.7 percent power at 10 years and 80.2 percent at 25 years, supported by Waaree Energies’ strong manufacturing pedigree and international certifications. This panel is an excellent choice for installers seeking a bankable, bifacial dual glass module with stable power output, controlled degradation and proven field reliability.
High power output in a compact footprint: The Bi-11-380 delivers 380 Wp of maximum power at Standard Test Conditions, allowing more energy generation from limited roof or ground space while keeping system design flexible for installers and project developers.
Bifacial energy gain for better yields: Dual glass bifacial construction captures light from the front and the rear side, increasing effective power output where there is ground or surface reflectivity and supporting higher kWh production over the system lifetime.
Robust dual glass durability: Tempered glass on both sides with anti reflection coating improves mechanical strength, offers resistance against ammonia, sand and hail, and supports long term reliability under high wind and heavy snow loads in challenging climates.
Stable performance across temperatures: Optimised temperature coefficients, including a -0.37 percent per degree Celsius power coefficient and -0.27 percent per degree Celsius voltage coefficient, help maintain output under high ambient and cell temperatures common in many regions.
Bankable warranties and certifications: A 10 year product warranty, 25 year linear performance warranty and compliance with IEC 61215, IEC 61730, UL 61730, IEC TS 62804-1 and ISO standards provide assurance for investors, EPC partners and end users planning long term projects.
Proven Indian manufacturer: Produced by Waaree Energies Ltd in India, the module benefits from independent factory assessment by Black & Veatch and supports local procurement for regional projects seeking reliable supply and technical support.
The Waaree Bi-11-380 bifacial dual glass solar panel converts sunlight into usable DC electricity through high efficiency monocrystalline PERC cells laminated between two sheets of tempered glass. When installed at the correct tilt and orientation, the front side of the panel captures direct and diffuse sunlight, while the rear side harvests reflected light from the ground or nearby surfaces to boost total energy yield. The generated DC power is routed through MC4 connectors and 4 mm² solar cables to a compatible string or central inverter, which converts it into AC power for on site consumption or grid export. Thanks to a maximum system voltage of 1500 volts and a 25 amp series fuse rating, the Bi-11-380 supports longer strings, reduced cable runs and optimised balance of system costs, especially in larger installations. Carefully engineered temperature coefficients and a low annual degradation rate help maintain strong output across the 25 year performance warranty period, making the module a dependable building block for modern solar projects.
Front side mono PERC energy conversion: Each of the 72 monocrystalline PERC cells absorbs incident sunlight on the front surface and converts photons into electrical current through the photovoltaic effect. The module delivers a maximum power of 380 Wp at a voltage of 40.11 volts and a current of 9.5 amps under Standard Test Conditions, ensuring efficient DC generation for both small and large arrays.
Bifacial backside power gain: The bifacial design allows the rear side of the module to remain active, capturing light reflected from bright surfaces like concrete, white rooftops or light coloured gravel. Depending on site albedo and system design, backside gain can significantly lift effective power output, as shown in the series where bifacial gains of 15 to 30 percent yield higher wattage and module efficiency figures compared with front side ratings alone.
Dual glass, cabling and system integration: The PERC cells are encapsulated between two 6.5 millimetre tempered glass sheets with an anti reflection coating, providing structural stiffness and improved light transmission while keeping moisture and contaminants away from sensitive cell layers. Power flows through an IP68 rated junction box, MC4 compatible connectors and 500 millimetre long 4 mm² cables into the DC side of the solar inverter. Designed for 1500 volt systems and a wide operating temperature range from minus 40 to 85 degrees Celsius, the module integrates seamlessly into modern rooftop and ground mount designs.
