Solar panels require very little maintenance. You should inspect your panels regularly for dirt and debris and wipe them down as needed. If you live in an area with lots of wind or dust, you may need to clean your panels more frequently.
Solar panel maintenance technicalities
Assuming you have a typical residential solar photovoltaic (PV) system, it will likely have two main components:
Solar panels, also called modules
An inverter
Solar panels are low-maintenance, but they’re not maintenance-free. You should inspect your panels regularly for dirt and debris and wipe them down as needed. If you live in an area with lots of wind or dust, you may need to clean your panels more frequently.
The inverter is a key component of your solar PV system, and it requires more maintenance than the panels. You should have your inverter serviced by a qualified technician every few years to ensure it’s operating properly.
