See this excerpt from our Best Solar Panels review article regarding Longi:
LONGi solar has grown rapidly over the last few years to become not only one of the largest Chinese solar panel manufacturers, but the largest monocrystalline cell manufacturer in the world. LONGi produce a wide range of cost effective and reliable panels which only use monocrystalline cells . In fact, part of the industry shift towards more efficient mono and mono PERC cells was due to the massive investment by LONGi in large scale mono wafer manufacturing.
The Hi-MO3 and Hi-MO4 mono PERC range of panels from LONGi Solar use the common 120 split-cell format and are becoming one of the more popular high-efficiency, low cost panels on the market.
