LEFN 550W solar panel

Reference: 21000012

This 550W solar panel from LEFN can be installed on large-scale photovoltaic installations, but also on smaller, residential installations.

These 550W solar panels have 144 monocrystalline half-crystalline half-cells and are characterised by their high efficiency and robust aluminium frame that allows the panel to be installed on different types of mounting systems.

Main features:

  • 144 Half-Cut cells.
  • The efficiency of the module is 21.3%. The split-cell technology has many advantages, such as higher efficiency, as the cells can be placed closer together, maximising the use and size of the solar panel.
  • The robust aluminium frame ensures that the modules can withstand wind loads up to 2,400Pa and snow loads up to 5,400Pa.
  • Low degradation and excellent performance, even under high temperature and low light conditions.
  • Positive power tolerance from 0 to +5W
  • High resistance to extreme environmental conditions, such as salt spray, ammonia or hail.
