  1. Turn off the solar panels (and make sure there is no electricity in the PV system before you start cleaning them).
  2. Check the entire installation for other problems, such as scratches, broken glass, dented plates, etc.
  3. Once you have checked that everything is in order and that the panels are switched off, pour plenty of lukewarm water over them. Ideally, the water should be demineralised so that it does not leave any residue on the solar panels' crystals.
  4. Then gently wipe the panels with the sponge in zigzags, here you can use a little dishwashing soap (being careful not to generate too much foam) in case the panel is very dirty.
  5. Pour in more water to remove any residue.
  6. Remove the water with the squeegee, just as you would remove the window panes at home.
  7. Wipe off any remaining water with the cotton cloth. Be sure to use gentle movements so as not to scratch or damage the glass.
