Jolywood JW-HD120N-R3 515W TOPCon Bifacial Dual-Glass Solar Panel
Model JW-HD120N-R3 | N-type TOPCon | 120 Half-Cell Monocrystalline | Bifacial | 1500V System Voltage
Product Overview
The Jolywood JW-HD120N-R3 515W TOPCon bifacial dual-glass solar panel is engineered for demanding residential, commercial, and utility projects where high yield and long-term reliability matter most. This advanced n-type TOPCon module delivers up to 515 watts of power with module efficiency up to 23.3 percent under standard test conditions. Bifacial dual-glass construction enables the panel to harvest energy from both the front and rear sides, increasing total energy generation over the system lifetime. With a robust 30 year linear performance warranty and low annual degradation of only 0.42 percent, this module supports stable long term returns on every installation. Its black dual-glass design and anodized aluminium frame provide a sleek appearance while maintaining excellent mechanical strength and resistance to harsh environments. Backed by Jolywood’s leading cell technology and stringent quality standards, this panel offers a reliable, future ready solution for modern solar arrays.
Key Benefits
High power density: Up to 515 Wp output and 23.3 percent efficiency allow more power on limited roof or ground space, supporting compact yet powerful system layouts.
Bifacial energy gain: Bifacial dual-glass design captures reflected light from the rear side, providing additional energy yield in bright, snowy, or reflective environments without extra footprint.
Stable long-term performance: The n-type TOPCon cell structure offers zero light induced degradation and supports only 1 percent first year loss, followed by just 0.40 to 0.42 percent annual degradation, preserving output over decades.
Robust construction: Dual-glass architecture, anodized aluminium black frame, and IP68 junction box enhance resistance to moisture, dust, and mechanical stress in harsh climates with high wind or snow loads.
Broad application range: The module suits BIPV designs, vertical facades, carports, and open-field systems, and operates from minus 40 to plus 85 degrees Celsius for global deployment.
Bankable warranty coverage: A 12 year product warranty and 30 year linear power warranty give strong assurance for investors and system owners planning long asset lifetimes.
How It Works
This Jolywood 515W solar panel converts sunlight into clean DC electricity using advanced n-type TOPCon monocrystalline cells arranged in a 120 half-cell layout. Light striking the front glass is absorbed by the high efficiency n-type cells, which generate electrical current with minimal resistive losses. At the same time, the bifacial architecture allows the rear side of the module to harvest light reflected from the ground, roofs, or surrounding surfaces, boosting the total energy yield. Dual-glass glazing protects the cells on both sides, while the anodized aluminium frame maintains structural stability. The generated DC power is sent through the IP68 junction box and 4 mm² cables toward a compatible inverter, where it is converted into AC electricity for on-site consumption or export to the grid. Optimized temperature coefficients and a favorable nominal operating temperature help sustain strong performance during hot conditions, enabling reliable output across seasons and installation types.
N-type TOPCon cell architecture: The panel uses n-type TOPCon cells that exhibit inherently low degradation and improved carrier lifetime compared with conventional p-type cells. This structure minimizes light induced degradation and supports higher efficiency, so more sunlight is converted into electricity over the entire operating life.
Bifacial dual-glass energy capture: Front and rear glass layers encapsulate the cells and allow light to reach both sides of the module. The rear side converts reflected and diffuse light into additional power, which can deliver 10 to 30 percent extra generation depending on site albedo and installation geometry.
Optimized performance under real conditions: The panel’s low temperature coefficient of minus 0.28 percent per degree Celsius helps limit power loss when module temperatures rise. Stable voltage and current at maximum power enable inverters and system designers to achieve efficient string configurations across a wide range of climates.
Reliable power delivery and protection: Three integrated bypass diodes in the IP68 junction box help reduce the impact of partial shading on power output. Quality sealing, robust connectors, and a 30 amp series fuse rating support safe, consistent operation within systems up to 1500 volts DC.
