Fluxes, solders and cleaning products for the solar industry - Made in Germany
Consumables for reliable, sustainable, green power generation.
Emil Otto offers a broad product portfolio for soldering solar modules, tabber and stringer material, and connecting cells. This includes solar flux and solar cleaning products, as well as tube solder, all of which have been specially developed to meet the high demands of the solar industry. Since 1901, the name Emil Otto has been synonymous with the highest quality and innovation in the development and manufacture of fluxes, solders, and cleaning agents. As an owner-managed company, we adhere to state-of-the-art development and manufacturing standards, as well as certified processes in quality and environmental management. Our products, including the world’s most extensive portfolio of fluxes, are used by leading companies in Germany and around the world.
Soldering flux for the solar industry
Our solar fluxes, which we have specially optimized for the production of solar modules and the connection of solar cells, are no-clean products. Our products leave no sticky residue and ensure clean processing, making them ideal for use as solar fluxes. Process tests with leading machine builders from the solar cell manufacturing industry confirm the reliability and quality of our products.
All alcohol-based solar fluxes can be offered as concentrates. These are packaged in reduced-volume packaging and shipped worldwide. As they do not have to be declared as hazardous goods, transportation is cost-reduced and therefore sustainable.
Cleaning products for the solar industry
Our biodegradable cleaning products such as EO-SMC-001 SOLAR-MODULE-CLEANER to EO-SMC-004 SOLAR-MODULE-CLEANER have been specially developed for the effective cleaning of solar modules. Thanks to their excellent wettability and flexibility, they can be easily applied by spraying, brushing or with automatic cleaning systems. All our solar cleaners are ideal for removing residues that could impair the efficiency of solar systems. Even in demanding environments, such as agri-photovoltaic parks, our cleaning media support reliable and effective cleaning of solar installations. Our innovative cleaning products not only facilitate the maintenance of solar systems, but also ensure long-lasting cleanliness without leaving behind harmful residues.
Our solar cleaners come with numerous benefits, such as being VOC-free, environmentally friendly and gentle on electronics and materials, making them perfect for use in photovoltaic systems. Furthermore, they do not contain any halogens, phosphorus compounds or inorganic salts and therefore support safe and sustainable cleaning. Their storage stability and complete washability with water round off the properties of our reliable cleaning agents.
Tubular solder especially for the solar industry
In addition to solar fluxes and solar cleaners, Emil Otto offers high-performance tubular solders.
