S-Energy SL45-72BGI-450S 445–455W Monocrystalline Bifacial Solar Panel
Model SL45-72BGI-450S | Monocrystalline Bifacial | 144 Cells | Bifacial | 1500V System Voltage
Product Overview
The S-Energy SL45-72BGI-450S is a high-performance bifacial solar panel designed for dependable energy production. This monocrystalline module delivers a 450 Wp maximum power rating and reaches 20.7% efficiency. Its bifacial design helps capture more available sunlight under the right installation conditions. The panel is built with 144 cells, durable tempered glass, and an anodized aluminum frame. It is a strong choice for commercial and utility-focused solar projects. The compact 40 mm profile supports practical installation planning. It also offers a 25-year power warranty and a 12-year product warranty.
Key Benefits
High power output: Delivers 450 Wp for strong energy generation in demanding installations.
Bifacial design: Uses both sides of the module to improve performance in suitable environments.
Efficient monocrystalline cells: Combines 144 cells with 20.7% efficiency for reliable solar conversion.
Durable construction: Features tempered anti-reflection glass, an anodized aluminum frame, and IP68 protection.
Project-ready reliability: Supports 1500V systems and includes a 25A series fuse rating for broader compatibility.
Long-term value: Backed by a 12-year product warranty and a 25-year power warranty.
How It Works
This bifacial solar panel converts sunlight into electricity through monocrystalline cells. The front side captures direct sunlight during normal operation. The rear side can capture reflected light from surrounding surfaces. That added rear-side contribution may improve total output in reflective environments. Performance depends on mounting height, ground reflectance, and site layout. The module is designed for stable operation across a wide temperature range. Its electrical design supports efficient energy harvesting and system integration.
Direct light capture: The front surface converts incoming sunlight into usable electrical power. This forms the main energy output during standard operation.
Rear-side gain: The bifacial structure allows the back side to absorb reflected light. This can increase production when the installation environment supports it.
System integration: The module supports 1500V maximum system voltage and MC4-compatible connectors. These features simplify use in larger solar arrays.
