Product type
TOPCon solar panels, or Tunnel Oxide Passivated Contact solar panels, are a type of high-efficiency photovoltaic module designed to convert sunlight into electricity. They utilize advanced technology that includes a thin layer of silicon oxide, which enhances light absorption and reduces electron recombination, leading to improved energy conversion rates. Typically made from monocrystalline silicon, these panels are known for their durability and performance in various environmental conditions.
| Efficiency | Up to 23% |
| Cell type | Monocrystalline silicon |
| Power output range | 300W to 450W |
| Temperature coefficient | -0.3%/°C |
| Dimensions | Approx. 1.6m x 1m |
When selecting TOPCon solar panels, buyers should consider the efficiency rating, power output, and physical dimensions to ensure compatibility with their installation. It's also important to specify the desired temperature coefficient, as this affects performance in varying climates. Certifications such as IEC 61215 and IEC 61730 may be relevant for quality assurance, and buyers should inquire about warranties and expected lifespans. Additionally, understanding the quantity needed for the project will help in obtaining accurate quotes.
