Solar fluxes help ensure stable and durable solder joints in cell bonding. Optimized flux technology can have a positive impact on process reliability, electrical reliability, and long-term module performance.
EO-S-009 FD is a halide-free, no-clean flux for soldering solar modules, tabber and stringer materials, and for joining solar cells. It leaves no sticky residue, has a solids content of 1.8 %, and is non-corrosive.
Fast Dry flux dries significantly faster than conventional fluxes. This allows the preheating temperature in the process to be reduced. This minimizes the thermal stress on sensitive TOPCon and heterojunction solar cells and facilitates gentle cell contacting.
Emil Otto's cleaning products are specially developed for cleaning photovoltaic systems. They gently remove typical contaminants such as pollen, dust, and organic residues from the module surface. This allows solar modules to be cleaned efficiently without damaging glass surfaces or coatings.
Professional cleaning products are specifically designed to meet the requirements of photovoltaic systems. They remove contaminants such as pollen or dust without damaging the module surface. One example is Emil Otto’s range of cleaning products, which were developed for use in the solar industry.
Yes, heavy or uneven soiling can cause what are known as “hotspots,” where certain areas of the solar module heat up more than others. This can damage the solar cells over time. Regular cleaning with suitable photovoltaic cleaners, such as products from Emil Otto, can reduce this risk.
Solar panels should be cleaned especially after the pollen season in the spring. During this time, large amounts of pollen often accumulate on photovoltaic panels. Regular visual inspections and cleaning with suitable cleaning agents, such as photovoltaic cleaners from Emil Otto, can help maintain the system’s performance.
Rain does not completely remove all contaminants from solar panels. Pollen, in particular, can form a sticky layer when combined with moisture, causing other particles to adhere to it. For thorough cleaning, special photovoltaic cleaners are therefore often used, such as cleaning products from Emil Otto.
Specially developed cleaning agents are suitable for photovoltaic modules; they remove dirt without damaging the glass surface or the modules’ coatings. Professional cleaners, such as Emil Otto’s photovoltaic cleaning products, are frequently used in the solar industry.
Pollen can reduce the performance of solar panels by approximately 2 to 10 percent. Pollen forms a fine film on the glass surface of photovoltaic modules, which scatters or absorbs sunlight. Special cleaning agents for solar systems, such as products from Emil Otto, help effectively remove these deposits.
