Welcome to the green energy world of Longi. With the mission of "Harnessing the sun's rays to create a green energy world", LONGi upholds its brand image of "robust and reliable, leading in technology". From innovative solar modules to comprehensive renewable energy solutions, Longi offers pioneering technologies to make the world cleaner and more sustainable.

Longi solar modules

Longi uses state-of-the-art monocrystalline cells based on HPBC (High Performance Bifacial Cell) cell technology for its solar modules. HPBC cell technology is characterised by its full-back welding technology, which increases resistance to microcracks and thus optimises the longevity of the solar modules. With the Hybrid Passivated Back Contact, or HPBC for short, Longi is not only setting new standards in terms of design. Compared to conventional PERC modules, the efficiency here is up to 1% higher; the cell efficiency is even over 25.3%.

Longi uses this advanced technology not only to increase the performance of its solar modules, but also to promote environmentally friendly and sustainable energy systems. This approach emphasises Longi's commitment to excellence and efficiency in photovoltaics.

Hi-MO 6 Series

With the Hi-MO 6 series from Longi, improvements have been made in the areas of performance, reliability, appearance and optimisation function compared to the previous series. In terms of the appearance of the solar module, the Hi-MO 6 series simplifies the complexity and redefines the aesthetic concept of photovoltaic modules.


Longi uses multi-busbar technology, in which each solar module is equipped with integrated busbars. These are busbars that are permanently printed on each solar cell. They collect the direct current generated and feed it to the busbars. By using more of these busbars, Longi reduces shading, shortens the transport distances and reduces the resistance in the modules.
