Mellerud Solar Panel & Solar Collector Cleaner is the ideal solution for gentle and effective cleaning of solar cells. It quickly and efficiently removes even stubborn dirt such as dust, general grime, soot residues, fine dust, and pollen, leaving the surface streak-free and residue-free. It improves the efficiency and lifespan of your equipment and creates a durable protection against new dirt with its water-repellent shield. Remove coarse dirt, leaves, and other impurities by gently wiping the modules without vigorous brushing to avoid damage. Mix the concentrate at a ratio of 1:20 (preferably with distilled water) to get 10 liters of ready-to-use solution. Apply the solution carefully to the solar panel with an especially soft sponge, cloth, or mop. Allow the cleaner to work for a moment and then rinse the surface thoroughly with water. Mixing ratio: 1:20 (0.5 liters of the package makes 10 liters of ready-to-use cleaner). Coverage: 10 liters of ready-to-use solution is enough to clean about 200 m² area. The main reason for using distilled water when diluting the cleaner: Depending on the residential area, the water contains more or less lime. In summer and during prolonged sunshine, the water evaporates very quickly, and the lime left in the water remains on the surface of the solar panels. The lime layer reduces the sun's effect on the panels and thus the efficiency of the panels. Distilled water contains no minerals and is the most suitable for diluting the concentrate.
