Model Bi-11-395 | Mono PERC Bifacial | 72 Full-Cell Monocrystalline | Bifacial | 1500V System Voltage
The Waaree Bi-11-395 395W bifacial monocrystalline PERC solar panel is designed for high energy yields and long term reliability. With advanced bifacial technology and a robust dual glass construction, this panel captures light from both the front and rear sides for increased power generation on suitable surfaces. Its monocrystalline PERC cells deliver up to 19.77% module efficiency at standard test conditions, making it a strong option for commercial rooftops, ground mounts, and premium residential systems. A maximum system voltage of 1500 V enables longer strings and optimized balance of system costs. The panel uses 72 full size mono PERC bifacial cells, precision laminated between tempered glass layers with anti reflection coating for improved light transmission and durability. Engineered to handle demanding environments, the Bi-11-395 operates across a wide temperature range from -40°C to 85°C, while maintaining stable performance through well controlled temperature coefficients. With a 10 year product warranty and a linear power warranty that guarantees 90.7% output at 10 years and 80.2% at 25 years, this module supports dependable energy production over decades. Quality certifications and PID resistant design further enhance confidence for long term solar investments using this Waaree Energies flagship module from India.
High bifacial energy yield: Bifacial mono PERC cells capture direct sunlight on the front and reflected light on the rear, increasing total kWh output per panel on reflective rooftops and ground surfaces.
Efficient 395W power class: At 395 Wp and up to 19.77% module efficiency, fewer modules are needed to reach target system capacities, helping reduce mounting hardware, cabling, and installation time.
Robust dual glass construction: Dual glass encapsulation with tempered glass and anti reflection coating supports long term durability, with resistance to ammonia, sand, hail, wind, and snow loads for reliable field performance.
Strong warranties and low degradation: A 10 year product warranty pairs with a linear power warranty that limits average annual degradation to about 0.79%, ensuring 90.7% power at 10 years and 80.2% at 25 years of operation.
Flexible system design: The 1500 V maximum system voltage and 25 A series fuse rating support longer strings and a wide range of modern inverters, giving designers flexibility for residential and commercial arrays.
Reliable performance in real conditions: Optimized NOCT power of 292.1 Wp and controlled temperature coefficients help maintain stable output across hot roofs and varied climates, supporting consistent long term energy savings.
The Waaree Bi-11-395 395W bifacial monocrystalline PERC solar panel converts sunlight into clean DC electricity using high efficiency mono PERC cells. Each module incorporates 72 bifacial cells that generate power from direct sunlight on the front surface and reflected light reaching the rear surface. The cells are embedded between tempered glass layers, protecting them from moisture and mechanical stress while allowing high light transmission. Under standard test conditions, the module delivers 395 W of power at a voltage of 40.88 V and current of 9.69 A at the maximum power point. In real outdoor conditions, its NOCT rating of 292.1 W at 37.52 V and 7.78 A gives a realistic view of everyday performance. Power flows from the cells through an IP68 rated junction box and MC4 compatible connectors into your chosen string configuration, then into a suitable grid tied or off grid inverter. The panel is designed to operate safely from -40°C to 85°C with carefully engineered temperature coefficients, which limit power loss as cell temperature rises. Over the life of the system, the linear performance warranty ensures gradual and predictable degradation, helping maintain strong energy yields for decades on rooftops or ground mount structures when installed to Waaree guidelines.
Bifacial mono PERC cell conversion: Photons strike the monocrystalline PERC cells through the front glass, freeing electrons that create an electric current within the cell structure. The bifacial design also harvests photons reflected from the ground or roof onto the rear surface, increasing total charge carriers and boosting energy yield compared with monofacial modules.
Dual glass protection and light management: Tempered dual glass with anti reflection coating enhances light transmission into the cells while protecting against impact, UV, and environmental stress. The anti reflection layer reduces surface losses so more sunlight reaches the active cell area, while the dual glass structure improves long term isolation and helps resist PID related performance losses.
Power delivery and system integration: Current from the interconnected cell strings flows into an IP68 rated junction box that houses bypass diodes and connection points. From there, MC4 compatible connectors and 4 mm² cables carry DC power to the array wiring, where strings are combined and routed to an inverter designed for up to 1500 V DC input, which then converts the DC output into usable AC electricity.
