JA Solar JAM54-S31-405MR 405Watt 108 1/2 Cells Black Backsheet Monocrystalline 30mm Black Frame Solar Panel

Manufacturer Part#: JAM54-S31-405MR

Assembled with 11BB PERC cells, the half-cell configuration of the modules offers the advantages of higher power output, better temperature-dependent performance, reduced shading effect on the energy generation, lower risk of hot spot, as well as enhanced tolerance for mechanical loading.

  • Higher output power
  • Lower LCOE
  • Less shading and lower resistive loss
