Do I Need to Turn Off Solar Panels to Clean?

When cleaning solar panels, safety is paramount. Many homeowners wonder if they need to turn off their solar panels before starting the cleaning process. Here’s what you need to know:

Safety Precautions

Generally, it is not necessary to turn off your solar panels to clean them. However, following safety guidelines is crucial:
