The main advantages of this solar panel are

  • - Solar panel with passivated solar cells back emitter or also called PERC which provides high efficiency (21.3%) compared to conventional solar cells.
  • - Slower power degradation compared to other solar panels thanks to its Low LID technology (Light Induced Degradation) or also called Light Induced Degradation. with a minimum initial degradation.
  • - Solar panel with better performance before situations of partial shading due to its 144 cells of smaller size (72 items).
  • - The split cells mounted on the LONGI 540Wp solar panel provide better performance due to the shorter bus bar length that generates the recombination of electrons
  • - High resistance to PID (Power Induced Degradation) degradation by voltage difference due to its high quality manufacturing process and selection of materials
  • - Reduced formation of micro-cracks in the cells of this Longi photovoltaic panel as they are smaller which favours the production of solar energy throughout its life.
  • - Less power loss of the solar panel due to the low operating current of the LONGI split cells.
  • - Solar panel capable of withstanding high static-snow mechanical loads of up to (5400Pa) and dynamic-wind loads of 2400Pa.
  • - Bifacial technology high performance.
