Solenso NRJ--W120SS 385 Bifacial HJT Monocrystalline Solar Panel
Model NRJ--W120SS 385 | HJT Bifacial | 120 Half-Cut Cells | Bifacial | 1500V System Voltage
Product Overview
The Solenso NRJ--W120SS 385 bifacial HJT monocrystalline solar panel delivers high output and long term efficiency for demanding projects. With a rated power of 385 watts and module efficiency up to 21.1 percent, this advanced module suits residential, commercial, and small industrial arrays. Heterojunction technology and half cut cell design support excellent performance in weak light and hot climates, so energy production stays stable across seasons. The bifacial construction can harvest extra energy from reflected light on the rear side, increasing total yield on bright surfaces. A robust anodized aluminium frame, dual glass design, and IP67 rated junction box protect the cells in harsh outdoor conditions. Optimized temperature coefficients and low annual degradation support reliable power generation across the full service life. This Solenso HJT module is a strong choice for roof mounted systems and ground mounts that require bankable performance and compact dimensions.
Key Benefits
High power density per square meter: Up to 21.1 percent efficiency allows more power from limited roof space, which supports compact system designs.
Bifacial energy gain: Rear side bifaciality around 90 percent helps capture reflected light, improving kWh production on suitable mounting surfaces.
Stable performance in heat: A low Pmax temperature coefficient of around -0.26 percent per degree Celsius reduces power loss during hot weather conditions.
Durable dual glass construction: Anti reflection coated solar glass and a rear ceramic patterned glass layer enhance durability and maintain transmission over time.
Long life warranty protection: A 20 year product warranty and 30 year linear power warranty support long term project bankability and predictable returns.
Flexible system integration: Compatibility with 1500 volt DC systems, MC4 connectors, and a 20 amp series fuse rating simplifies integration with modern inverters.
How It Works
This Solenso HJT bifacial solar panel converts sunlight into direct current electricity using high efficiency heterojunction cells. Each 166 by 83 millimeter cell combines crystalline silicon with thin amorphous layers, which increases carrier collection and reduces losses. The module uses 120 half cut cells wired in a layout that reduces resistive losses and improves shade tolerance. Front side irradiance and rear reflected light both contribute to power generation when the panel is mounted over bright or reflective surfaces. The module operates at a maximum power voltage of about 37.7 volts and current around 10.22 amps under standard test conditions. Generated DC power is routed through the IP67 junction box and MC4 connectors to the string wiring and inverter. The inverter then converts the DC power to usable AC electricity for on site loads or export to the grid. A low operating temperature coefficient helps the panel maintain strong output as cell temperatures rise in direct sun.
Heterojunction half-cut cell design: The 120 half cut HJT cells use a layered junction structure that captures more photons and reduces recombination losses. Cutting the cells halves the current in each path, which lowers resistance and enhances efficiency and reliability.
Bifacial power generation: The transparent glass backsheet allows light to reach the rear cell surfaces, so the panel can generate energy from both sides. When installed above bright roofing, concrete, or ground coverings, this rear side contribution can significantly raise total output.
Optimized thermal and electrical behavior: A nominal operating cell temperature of about 44 degrees Celsius supports stable operation in varied climates. Carefully matched Voc, Isc, and current ratings align with common string inverter windows, which helps maintain strong performance across a wide irradiance range.
