About LONGi

LONGi, a company founded in 2000, is one of the leading manufacturers of PV modules and uses the most cutting-edge technologies to better exploit the power of solar energy. LONGi has branches in 150 countries in the world, among which China, Vietnam, and Malesia for the production plants and the USA, Japan, Germany, India, Australia, Arab Emirates, and Thailand for sales offices. 

Over the years LONGi created many partnerships with universities and research institutes to establish a constant brainstorming that led to the development of new technologies to improve the exploitation of solar energy. Thanks to the constant investments in R&D, LONGi can optimize the cost-power ratio by using monocrystal modules with high efficiency, assured by the PERC technology. 

LONGi Modules

BayWa r.e. Solar Systems Italy, supplies two series of LONGi solar modules: the Hi-MO 4m series and the new Hi-MO5 series, both mono-perc half cut, with 9 busbar and gallium-doped technology for a higher module efficiency.

Technology of the new series LONGi Hi-MO 5

The new modules of the series Hi-MO 5 operate at a current of 13 A and thanks to their advanced technology, they have a higher degree of efficiency compared to the Hi-MO 4. 

Bifacial

Energy is generated by both the module’s sides, with an increase in energy production, maximum efficiency of 21.5%, and a power range from 535 to 555 W. The bifacial structure of the module, combined with the PERC technology, allows it to have a high yield, suitable for big PV plants. Moreover, the double-glass packing structure of the bifacial module guarantees higher resistance to different environments, such as water steam, salt mist, ammonia environments, etc...

Integrated Segmented Ribbon technology

It allows a reduction of the welding space between the modules, thanks to the use of a triangular section that creates a stronger bond between the cells, thus maximizing the use of front light. In comparison with former technologies, there is a documented efficiency increase of 0.3%, because the surface available for catching the sunbeam increases, and the empty spaces are minimized.

Wafer M10

They represent the optimal cell size in order to assure the maximum module efficiency and are less susceptible to mechanical impacts. Using the wafer M10 – 182 mm energy and material consumption are considerably reduced, thus making the production process cleaner and with a lower carbon footprint. Further, they assure a longer life cycle and a greater strength compared to the former type of cells, reducing the related installation and maintenance costs.   

LONGi Warranty

LONGi offers a warranty of 12 years of the product, both for mono facial modules of the series Hi-MO 5m and Hi-MO 4m, and for the bifacial modules Hi-MO 5. Moreover, for both the mono facial series, there is a performance warranty of 25 years, while for the bifacial ones the warranty is 30 years.
