LONGi is a leading company in the solar energy industry and offers comprehensive solutions for the use of renewable energies. With a focus on high-efficiency monocrystalline silicon wafers and photovoltaic modules, LONGi contributes to increasing energy efficiency worldwide. The company is committed to sustainable development and innovation and supports various industries in reducing their CO₂ emissions. Thanks to its advanced technologies and global presence, LONGi is setting standards in the industry and driving the transformation towards a green energy future.

LONGi: Comprehensive in-house production for the highest quality

LONGi is a renowned manufacturer of solar modules with a deeply integrated supply chain. The company, which was founded in 2000, has developed from the production of wafers to a complete portfolio comprising wafers, cells and modules - all produced in-house. Only the silicon is bought in, while the remaining processes are covered internally. With numerous patents and 18 efficiency records, LONGi sets standards in the industry. The company has increased its focus on the German market and continuously demonstrates technological advances in solar technology.

Aesthetics and efficiency: the new Ultra-Black modules

A highlight in LONGi's portfolio is the Ultra-Black module, which meets the highest aesthetic standards. This module impresses with a completely black surface, free of the bluish shimmer that is often seen with conventional “full black” modules. This is achieved by a specially micro-textured and anti-reflective glass that is also dirt-repellent. Fingerprints or dirt particles hardly stick, which makes maintenance easier. The modules are visually ideal for applications where aesthetics play a central role, such as residential buildings with visible roof surfaces. However, the efficiency of black modules is slightly reduced as they reflect less light than modules with white backsheets.

Flexibility in size and technology

LONGi offers a wide range of modules, including different sizes and cell types, to meet the most diverse requirements. With modules ranging from 54 to 72 cells, optimum adaptation to the available roof area is possible. The bifacial glass-glass modules with rear contacts are particularly innovative. These rear contact cells maximize light absorption, as the entire front side is used for solar energy. At the same time, the rear contacts increase the mechanical load capacity of the modules. This technology is particularly advantageous for projects where maximum performance and durability are required.

Future-proof solutions thanks to larger module sizes

The move towards larger modules is facilitated by updated building regulations, which allow modules over two square meters in more and more federal states such as Bavaria, Hesse and North Rhine-Westphalia. These changes allow the installation of larger modules, which is particularly advantageous for commercial applications. LONGi offers solutions that meet the increasing demands for efficiency and space utilization.
