Product type
PERC solar cells, or Passivated Emitter and Rear Cell solar cells, are a type of photovoltaic cell that enhances the efficiency of solar energy conversion. They are typically made from silicon, with a passivation layer added to the rear side to reduce electron recombination, allowing for better light absorption and energy generation. This technology is widely used in solar panels to improve overall performance and energy yield compared to traditional solar cells.
| Efficiency | Up to 23% or higher |
| Material | Monocrystalline silicon |
| Cell size | 156 mm x 156 mm or larger |
| Temperature coefficient | -0.3%/°C |
| Standard power output | Up to 400 W per panel |
When choosing PERC solar cells, consider the efficiency rating, as higher efficiency will yield more energy from the same amount of sunlight. It's also important to specify the desired power output and size of the solar panels. Certifications such as IEC 61215 and IEC 61730 can indicate quality and reliability. Be sure to request information on warranties and expected lifespan as well. Quantities may vary based on project size, so ensure to provide details on your specific requirements.
