ET Solar Photovoltaic Solar Panel 320W - Black Frame

Premium Range with 19.55% Cell Efficiency

Reliable Quality and Outstanding performance: 

Knowing voltage increase as one of the effective methods to decrease line loss, ET’s Product Department and R&D Team are devoted to developing high-efficient module while we are trying any probability of more power output by technology innovation like upgrading voltage level and decreasing line loss. ET 1500VDC Module is designed to realize a lower LCOE of the power plant, by allowing longer cable operation and longer string to pull down the combiner-box quantity and narrow cable size.


  • Designed for compatibility with advanced voltage 1500V solar plant
  • Significant saving on BoS cost
  • Extending string length up to 50%
  • Enhanced module durability
  • Higher system performance
