Timing matters in solar panel cleaning. Very hot afternoons, extreme roof temperatures, and unsafe weather are usually not ideal. The best time is often when conditions are safer, cooler, and more practical for rooftop work.
Panels exposed to strong afternoon sunlight can become very hot. Cleaning in extreme heat may be uncomfortable, less practical, and harder to manage safely on the rooftop.
In many Indian cities, dry weather leads to faster dust buildup. Cleaning may be needed more often during long dry stretches, especially when rain is not helping wash away loose surface dust.
The best approach is to look at your environment, not only the calendar. Heavy dust, bird activity, nearby construction, and visible buildup are more useful signals than waiting for a fixed date.
