Upsolar UP-B385MH-G 385W Bifacial HJT Solar Panel
Model UP-B385MH-G (60M6) | Bifacial HJT | 120 Half-Cell | Bifacial | 1500V System Voltage
Product Overview
The Upsolar UP-B385MH-G is a high-efficiency bifacial HJT solar panel designed for reliable long-term energy production. It uses 120 half-cut cells and glass-glass construction to support strong performance in demanding environments. With a maximum power output of 385 Wp and module efficiency of 21.14 percent, this module is built for projects that value consistent yield and dependable quality. The panel also offers a positive power tolerance of 0 to +3 percent, which helps deliver strong output from the start. Its compact dimensions, low degradation profile, and durable materials make it suitable for residential, commercial, and large-scale solar installations.
Key Benefits
High Power Density: The module delivers 385 Wp in a compact footprint. That helps maximize energy output where roof space is limited.
Bifacial Energy Gain: Bifacial technology can capture light from both sides. This supports improved real-world generation under suitable installation conditions.
Strong Durability: Tempered glass, anodized aluminium, and IP67 junction box protection improve resilience. These features help the panel perform reliably over time.
Low Degradation Profile: The linear warranty coverage supports 95.75 percent power after 10 years and 90.75 percent after 30 years. That provides strong long-term performance confidence.
Excellent Environmental Resistance: The module is rated for salt mist and ammonia resistance. It is also designed to minimise cell degradation in extreme environments.
How It Works
This module converts sunlight into electricity through advanced HJT cell architecture and a bifacial glass-glass design. Front-side illumination produces the main electrical output, while rear-side light can add extra generation when the installation environment reflects light effectively. The half-cut cell layout helps improve energy handling and reduce losses under partial shading. Together, these features support stable performance, improved durability, and a lower levelized cost of electricity across the system lifetime.
HJT Cell Conversion: The heterojunction structure combines different silicon layers to support efficient charge collection. This helps the module achieve high conversion performance.
Bifacial Rear-Side Output: Light reaching the rear surface can also be converted into power. This can increase total yield in bright, reflective settings.
Half-Cut Cell Design: The 120 half-cut cell layout helps reduce resistance and improve shade tolerance. That supports steadier output during changing site conditions.
