Introduction of LONGI company
Longi solar company is the second producer of high power solar panels with advanced technologies in the world.
Longi solar solar panels are in the first category or Tier1 in the classification of panels. The companies that are in this category are generally large companies with high investment volumes in the production sector as well as research and development units.
LR4-72HPH series panels of Longi company are produced in powers of 425 watts to 455 watts. The use of PERC technology is only one of the features of this company’s monocrystalline panels. These panels use half-cut cells that dramatically increase the production of electrical energy in adverse weather conditions such as cloudy days.
Half cut cell technology
Half cut cell technology has recently entered the solar panel market around the world after passing several successful laboratory tests.
Due to the complexity of the structure of this technology, limited companies in the world are able to produce these panels, and Longi solar company is considered one of the best among those limited number of producers.
