Sail Solar SAS445MB-120HG 445W Bifacial Monocrystalline Solar Panel
SAS445MB-120HG | Bifacial TOPCon | 120 Half-Cell | Bifacial | 1500V System Voltage
Product Overview
The Sail Solar SAS445MB-120HG represents a pinnacle in modern photovoltaic technology. This 445W module utilizes advanced Bifacial TOPCon cell architecture to maximize energy harvest. Unlike standard panels, it captures sunlight from both the front and rear surfaces. This dual-sided capability significantly boosts overall system efficiency in diverse lighting conditions. The monocrystalline construction ensures superior durability and long-term performance stability. Its robust anodized aluminum frame withstands heavy snow loads up to 5400 Pa. The tempered glass offers excellent protection against environmental stress and physical impact. This panel is ideal for residential rooftops, commercial installations, and large-scale solar farms. It operates efficiently across a wide temperature range of -40°C to +85°C. The high 1500V system voltage supports flexible string configurations for complex arrays. Sail Solar Energy Co., Ltd. manufactures this product with strict quality controls in China. The 445W output provides reliable power for various energy demands. Its compact yet powerful design optimizes space utilization effectively. The 20.57% module efficiency stands out among competitive products in the market. This solution delivers exceptional value for investors seeking high-yield solar assets.
Key Benefits
Bifacial Energy Harvest: Captures sunlight from both sides to increase total power generation by up to 30%.
High Efficiency Rating: Achieves 20.57% module efficiency with advanced TOPCon cell technology for superior output.
Extreme Durability: Features a strong frame supporting 5400 Pa front load and 2400 Pa back load resistance.
Wide Temperature Range: Operates reliably from -40°C to +85°C, ensuring performance in harsh climates.
Low Degradation: Exhibits excellent PID, An-PID, and low LID performance for long-term power stability.
How It Works
The Sail Solar SAS445MB-120HG converts solar energy into electricity through a sophisticated multi-step process. Sunlight strikes the 120 high-quality monocrystalline cells arranged in a 2x60 orientation. The Bifacial TOPCon design allows photons to penetrate the rear side of the cell structure. This dual-sided exposure captures reflected light from the ground or surrounding surfaces. The absorbed energy excites electrons within the silicon lattice to generate an electric current. A built-in junction box with three diodes manages the flow of this generated power. The system ensures safe transmission via the MC4 connector and 4mm2 output cables. Advanced thermal management maintains optimal operating temperatures even under high irradiance. The anodized aluminum frame provides structural integrity while dissipating heat efficiently. This design minimizes hot spot risks and enhances overall module longevity. The high voltage output supports efficient integration with modern grid-tied inverters.
Dual-Side Photon Capture: The bifacial design captures direct sunlight on the front and reflected light on the rear. This increases total energy yield significantly compared to standard single-sided panels.
TOPCon Cell Technology: Tunnel Oxide Passivated Contact technology reduces electron loss at the cell interface. This results in higher voltage and current output for every watt of sunlight received.
Thermal Regulation: The panel operates efficiently across a wide temperature range. The negative temperature coefficient of Pmax ensures stable performance even in hot weather conditions.
