Solar panel cleaning is the most common maintenance performed on residential phototactic (PV) energy systems, especially those in dry or windy areas. When dirt, dust, debris, or animal droppings accumulate on the surface of your solar panels, blocked sunlight can significantly reduce their energy production.
When it comes to cleaning solar panels, using the right products is crucial to avoid damaging the panels. Here are some recommended products: Mild Detergent: A few drops of mild dish soap mixed with water are usually sufficient.
