Model SS480M10GH-20/UH | N-Type TOPCon | 120 Half-Cut Cells | Bifacial | 1500V System Voltage
The Smart Solar Technologies SS480M10GH-20/UH 480W N-Type TOPCon Full Black Bifacial Solar Panel is designed for high efficiency and long term reliability in demanding residential and commercial projects. This full black bifacial module combines advanced N-type TOPCon cell technology with a glass-glass construction for impressive power output and excellent durability. With a maximum power of 480W and module efficiency up to 22.24 percent, strong performance is delivered even in limited roof space. Half-cut 120 cell architecture and SMBB technology improve light capture and reduce electrical losses across the module. Bifacial generation allows additional energy harvest from reflected light on the rear side, increasing overall yield and helping reduce levelized cost of energy. The robust frame and IP68 junction box support dependable operation under high wind and heavy snow loads. This panel suits grid tied rooftop systems, ground mounted arrays, and larger commercial installations that require stable performance and attractive full black aesthetics.
High power density for limited roof space: Up to 480W output and 22.24 percent efficiency help maximize energy production on compact residential and commercial roofs.
Bifacial design for greater energy yield: Rear side generation captures reflected light, typically increasing module power by 5 to 25 percent in suitable mounting conditions.
Durable glass glass construction: Dual 2.0mm tempered glass layers protect cells from moisture, UV, and mechanical stress for extended field life.
Enhanced mechanical load resistance: The module is certified to withstand snow loads up to 5400 Pascal and wind loads up to 2400 Pascal on appropriate mounting structures.
Reliable performance and PID resistance: Optimized mass production processes and materials provide excellent anti PID behavior and long term power stability in harsh environments.
Premium full black appearance: Uniform black cells, back glass, and frame create a sleek look that blends well on modern rooftops and visible facades.
This N-Type TOPCon bifacial solar panel converts sunlight into clean DC power using advanced photovoltaic cell technology on both sides of the module. Light that strikes the full black front surface is absorbed by the N type mono cells, where electrons are released and guided through the multi busbar grid to the junction box. Half cut 120 cell layout reduces internal resistance, allowing higher output current with lower electrical losses. Additional irradiance that reflects from bright surfaces behind the array is captured by the bifacial rear side, creating extra energy generation over the year. The dual glass encapsulation shields the cells from moisture and mechanical stress while permitting high transparency on both sides for optimal light capture. Generated DC energy then flows through an inverter, where it is converted into AC electricity for on site consumption or export to the grid, depending on system design and local regulations.
N-Type TOPCon cell conversion: N type TOPCon cells offer low degradation and improved light induced performance compared with conventional P type cells. Their passivated contacts reduce recombination losses, so more of the captured sunlight is converted to usable electrical power over the lifetime of the system.
Bifacial energy harvesting: Both front and rear sides of the glass glass module are active, so reflected and diffuse light behind the panel can be used. When installed above reflective surfaces such as light concrete, white membranes, or snow, total output increases, improving project yield and investment returns.
Half cut SMBB power collection: Each cell is split into two halves, lowering operating current and reducing resistive losses in the cell strings and busbars. SMBB technology uses more and thinner busbars to shorten current paths, enhance shade tolerance, and keep performance stable under real world conditions.
