Sail Solar SAS445M-144H 445W PERC Monocrystalline Solar Panel
SAS445M-144H | PERC | 144 Half-Cell | Monofacial | 1500V System Voltage
Product Overview
The Sail Solar SAS445M-144H is a high-performance monofacial solar panel designed for reliable energy generation. This unit delivers 445 watts of peak power with 20% module efficiency. It features advanced PERC technology to enhance light absorption and power output. The panel includes 144 half-cut monocrystalline cells arranged in a 6x24 configuration. This design minimizes resistive losses and improves performance in low-light conditions. Built with tempered glass and an anodized aluminum frame, it withstands harsh weather. The operating temperature range spans from -40°C to +85°C for global suitability. It supports a maximum system voltage of 1500V DC for efficient grid-tie systems. The IP68-rated junction box ensures protection against dust and water ingress. Sail Solar manufactures this product in China with strict quality controls. It is ideal for residential, commercial, and utility-scale solar projects. The panel offers a positive power tolerance of 0% to +1% for guaranteed output. Its robust construction ensures long-term durability and consistent energy production.
Key Benefits
High Power Output: Delivers 445W peak power for maximum energy generation per panel.
PERC Technology: Enhances cell efficiency and improves performance in low-light environments.
Half-Cell Design: Reduces resistive losses and boosts output with 144 split cells.
Weather Resilience: Operates safely from -40°C to +85°C with IP68 junction protection.
High Voltage System: Supports 1500V DC max system voltage for efficient large-scale arrays.
How It Works
The Sail Solar SAS445M-144H converts sunlight into electricity using advanced photovoltaic principles. Sunlight strikes the 144 monocrystalline PERC cells embedded within the panel. These cells absorb photons and release electrons to generate a direct current. The half-cut cell design splits each cell to lower internal resistance significantly. This reduction in resistance allows more current to flow to the output terminals. The PERC layer reflects unused light back into the cell for secondary absorption. This process increases overall efficiency and power output beyond standard panels. The generated DC electricity flows through the MC4 connectors to the inverter. The inverter then converts this power into usable AC electricity for your home or grid.
Photon Absorption: Sunlight photons hit the silicon cells and release electrons to create current. This process starts the energy conversion cycle immediately upon exposure.
Half-Cell Efficiency: Splitting cells reduces resistance and improves low-light performance. This design ensures consistent power even when the sun is weak.
PERC Reflection: The PERC layer reflects light back into the cell for another pass. This reflection maximizes photon usage and boosts total efficiency.
