Fluxes, flux gels, solders and cleaning agents for the solar industry – Made in Germany
Consumables for reliable, sustainable, green power generation
Emil Otto offers a comprehensive product portfolio for the solar industry, including specialized consumables for the soldering of solar modules, tabber and stringer material, and the connection of solar cells. This includes fluxing agents, cleaning agents and tubular solder, all specifically developed to meet the high demands of solar production. Since 1901, Emil Otto has been synonymous with top-quality and innovation in the development and manufacturing of fluxes, solders, and cleaning agents.
As an owner-managed company, we pride ourselves on using state-of-the-art development and manufacturing standards, as well as certified processes in quality and environmental management. Our products, including the most extensive flux portfolio globally, are trusted by leading companies in the solar industry, both in Germany and abroad.

Soldering flux for the solar industry
Our fluxes, specifically optimized for solar module production and solar cell connections, are No Clean products. These fluxes leave no sticky residue, ensuring clean processing and making them perfect for use as solar fluxes. Extensive process tests with leading machine builders from the solar cell manufacturing industry confirm the reliability and quality of our products.
We also offer solar fluxes as concentrates. These are provided in reduced-volume packaging and shipped worldwide. Since these products are not classified as hazardous goods, transportation costs are minimized, which contributes to sustainable solar manufacturing.
Solar flux gels
Besides this, we produce solar flux gels, which are based on the proven activators of the solar fluxes from Emil Otto and thereby prevent unwanted cross-reactions. Thanks to a highly concentrated formulation, they provide outstanding wetting, spreading and soldering quality on tin-copper metallization, which are increasingly replacing the previous tin-silver metallization. The uniform activators in the Emil Otto solar flux gels avoid chemical interactions between different fluxes. This ensures a high level of process reliability and consistently high product quality.
Cleaning agents for the solar industry
Our biodegradable cleaning agents such as EO-SMC-001 to EO-SMC-004 are specifically formulated for effective cleaning of solar modules. Thanks to their excellent wettability and flexibility, they can be easily applied by spraying, brushing, or using automated 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 products support the reliable and effective cleaning of solar installations. Our innovative cleaning agents not only simplify solar system maintenance but also ensure long-lasting cleanliness without leaving harmful residues.
Our solar cleaners come with numerous benefits, such as being VOC-free, environmentally friendly, and gentle on electronics and materials. These properties make them perfect for use in the world of photovoltaic. Additionally, our cleaners do not contain halogens, phosphorus compounds, or inorganic salts, supporting safe and sustainable cleaning. Their storage stability and complete washability with water further enhance the reliability of our cleaning products.
Tubular solder especially for the solar industry
In addition to fluxes and cleaning agents, Emil Otto offers high-performance tubular solders, specifically designed for use in the solar industry. These solders ensure reliable and durable connections for solar panel assembly.
