The chemicals that can be used to clean solar panels depend on the type of dirt or debris on the panel's surface. Generally, it is recommended to use mild, non-abrasive cleaning solutions to avoid damaging the solar panel's surface. Here are some common chemicals that can be used to clean solar panels:
Water: Plain water can be used to clean solar panels if they are not too dirty. However, if the panels are covered in dirt, dust, or bird droppings, water alone may not be enough.
Soap and water: A mixture of mild soap and water can be used to clean solar panels. Use a soft-bristled brush or sponge to gently scrub the panels, and rinse with clean water.
Isopropyl alcohol: Isopropyl alcohol can be used to remove stubborn stains, grease, or oil from solar panels. Mix equal parts of water and isopropyl alcohol, and use a soft cloth or sponge to clean the panels.
Vinegar: A mixture of white vinegar and water can be used to remove mineral deposits or hard water stains from solar panels. Mix one part vinegar with three parts water, and use a soft cloth or sponge to clean the panels.
Commercial solar panel cleaning solutions: There are many commercial cleaning solutions available that are specifically designed for cleaning solar panels. These solutions are typically mild, non-abrasive, and environmentally friendly. It is important to follow the manufacturer's instructions when using these solutions.
