one metric is cleaning the panels eg dust, bird stuff, then the issue of dirt etc accumulating on the edges of the panels

"A one-time cleaning for a 10-megawatt solar farm— which provides enough electricity to power 2,000 homes for a day—can cost an estimated $5,000.

Simpson said in some areas, such as California’s Central Valley where “soiling rates get sufficiently high and the rain sufficiently low,” it makes economic sense to clean the panels more than once a year. "

Cleaning panels maybe an issue in polluted areas but IMO it will be the least of CB's problems. I check mine every few months but have only ever cleaned them once in over 10 years and it made no detectable difference to their output. I am in a rural area with a 600mm annual average rainfall.
