Product type
HJT solar panels, or Heterojunction Technology solar panels, combine crystalline silicon and amorphous silicon layers to enhance efficiency and performance. This innovative design allows for better light absorption and lower temperature coefficients, making them suitable for various climates. HJT panels are typically used in residential, commercial, and utility-scale solar installations due to their high efficiency and durability.
| Efficiency | Up to 24% |
| Temperature coefficient | -0.3%/°C |
| Cell structure | Crystalline silicon with amorphous silicon layers |
| Standard sizes | 60-cell and 72-cell configurations |
| Power output range | 300W to 450W |
| Warranty | 25 years performance warranty |
When choosing HJT solar panels, consider the efficiency ratings and power output that best fit your energy needs. Specify the desired wattage, panel size, and any specific certifications required for your project. It's also important to inquire about the warranty terms and the manufacturer's reputation. For larger installations, discuss bulk purchasing options and potential discounts.
