How often should solar panels be cleaned depends on various factors such as location, climate, and environmental conditions. In general, it’s recommended to clean solar panels at least once or twice a year to maintain optimal performance.
However, if you live in an area with high levels of dirt or pollution, or if your panels are frequently exposed to fauna or flora debris, more frequent cleaning may be necessary. Monitoring your solar panels regularly and cleaning them as needed can help ensure maximum performance.
It also depends on the usage of the panels. Residential solar panels are recommended to be cleaned every 6 months or yearly. Industrial and commercial cleaning would be required every 3 months and sometimes even every other month or in extreme cases, monthly.
