Bird droppings, dust, and pollution can all reduce solar panel efficiency.
Leaving your panels dirty will reduce solar output and thus increase your solar payback period.
You might need to clean more often if you are located in an arid region or near a pollution source, or if your panels are mounted flat.
Monitor solar output before and after a cleaning to measure its impact; adjust the cleaning frequency accordingly.
