Good news—How Often Does a Solar Panel Need to Be Cleaned? Not that often! Most panels are low-maintenance and just need a cleaning about twice a year, depending on your local weather and dust levels. Rain usually helps keep them clear, but if you notice a drop in performance or a build-up of grime, it’s time for a rinse. Keeping your panels clean ensures they soak up the sun efficiently and keep your energy output high. We can also help you set up a maintenance plan so you never have to stress about it. Clean panels = more power and more savings.
