    AI Overview
    A 490W half-cell solar panel is a high-power, high-efficiency module designed primarily for commercial, industrial, and large-scale residential projects. These panels typically feature 156 half-cut monocrystalline PERC cells, which split standard cells in half to reduce internal resistance, improve performance in low-light conditions, and reduce the risk of hot spots. 
    Key Features and Specifications (e.g., Silfab SIL-490-HN): 
    • Power Output: 490 Watts (STC)
    • Efficiency: Up to 20.9%
    • Cell Configuration: 156 half-cells
    • Dimensions: Approximately 2263 mm x 1037 mm x 35 mm (approx. 89 x 40.8 x 1.37 inches)
    • Weight: 25.8 kg (56.9 lbs)
    • Voltage (
      Vpmaxcap V sub p m a x end-sub
      𝑽𝒑𝒎𝒂𝒙
      ):       ~45-46 V
    • Current (
      Ipmaxcap I sub p m a x end-sub
      𝑰𝒑𝒎𝒂𝒙
      ):       ~10.5-10.8 A
    • Warranty: Often includes 25-year workmanship and 30-year linear power performance guarantees
    • Durability: High-wind and snow load resistance (e.g., 5400 Pa front load) 
    Main Advantages: 
    • Higher Efficiency: Half-cut cells reduce power loss and improve performance.
    • Shading Tolerance: The 156-cell configuration, often paired with 3-part split junction boxes, allows for better performance if one part of the panel is shaded.
    • Ideal for Large Roofs: Large format (over 2 meters in length) makes them efficient for high-density, commercial installations.
    • Bifacial Option: Some models, like the Qcells 490W Q.PEAK DUO XL-G10.3/BFG, are bifacial, allowing power generation from both sides. 
    Price and Availability: 
    • Individual panels can cost around $295 to over $515 depending on the brand and supplier.
    • Pallet pricing is available for large projects (e.g., 31 modules from SolarFlexion).
