Model NRJ--W120SS 380 | HJT Half-Cut | 120 Half-Cell | Bifacial | 1500V System Voltage
The Solenso NRJ--W120SS 380W HJT bifacial monocrystalline solar panel delivers high efficiency in a compact footprint for residential, commercial, and industrial arrays. With advanced heterojunction half-cut cells, this 380 Wp module converts more sunlight into usable power, even in weak light and hot climates. Its bifacial design increases total energy yield by harvesting light from both the front and rear sides. A module efficiency of 20.9% helps you generate more power from limited roof or ground space. The NRJ--W120SS 380 is engineered for long‑term reliability, with a 20‑year product warranty and a 30‑year linear performance warranty. Durable construction features 2.0 mm anti‑reflection glass, POE encapsulation, and an anodized aluminum frame for excellent mechanical strength. This panel is manufactured by Solenso Electronic Materials Co., Ltd. in Taiwan, ensuring consistent quality and reliable supply for demanding projects. It is ideal for grid‑tied systems operating up to 1500 V, where long string lengths and strong lifetime performance are essential.
High power density: The 380 Wp output and 20.9% efficiency allow more power per square meter, which maximizes system capacity on constrained roofs.
Bifacial energy gain: Bifacial heterojunction cells capture reflected light from the rear side, increasing yield on bright ground or reflective surfaces.
Superior temperature performance: A low -0.26%/°C power temperature coefficient preserves output during hot weather, which supports higher annual production.
Long‑term reliability: A 20‑year product warranty and 30‑year linear power warranty, with only 0.4% annual degradation, help secure project returns.
Robust construction: Anodized aluminum frame, IP67 junction box, and high‑quality POE encapsulant offer protection against moisture, dust, and mechanical stress.
Easy system integration: Standard MC4‑compatible connectors and 4 mm² output cables help streamline installation and reduce on‑site wiring time.
The Solenso NRJ--W120SS 380 solar panel converts sunlight into clean DC power using advanced bifacial heterojunction technology. Each of the 120 half‑cut cells is made from high‑efficiency monocrystalline silicon combined with thin amorphous layers, which improves charge collection. Sunlight striking the front glass is absorbed by the HJT cells and converted into electrical current, which then flows through multi‑busbar conductors into the junction box. The bifacial design also uses light reflected from the ground or nearby surfaces, captured through the rear glass to boost generation. This DC power is fed through MC4‑compatible connectors to an inverter, where it is converted to AC power suitable for homes, businesses, or commercial facilities. The system operates safely within a wide temperature window, supported by optimized temperature coefficients that stabilize real‑world performance across seasons.
HJT half‑cut cell architecture: Heterojunction cells combine crystalline and thin‑film layers to reduce losses and increase efficiency. Half‑cut layout lowers resistive losses and reduces current in each cell string, which improves shade tolerance and boosts energy yield.
Bifacial light harvesting: The module uses a glass‑glass style configuration with active rear cells that capture reflected light. This rear‑side contribution is especially valuable over bright surfaces, where system designers can achieve higher kWh per installed kW.
Thermal and electrical stability: Optimized temperature coefficients minimize output loss as cell temperature rises during peak sun. A maximum system voltage of 1500 V allows long strings, while controlled power tolerance of 0 to +1% helps ensure predictable commissioning values.
