For those of us without snow cover; dust, dirt, & leaves also cut the power produced, obviously not as much as snow cover. Still, you should keep solar panels clean.
Who likes to go up on the roof?

Yup... I’ve watched the trend meters at the home of a family member who has about 15 panels. He figured out very quickly that dust settling on the panels would degrade performance and has actually got into the routine of doing a washdown of the panels once a month... frequently enough that he is set up so it can be done easily from the ground. Like all things, there is no free lunch... and there will be implications that don’t seem to stop. Down the road, the panels will be a total nuisance when the roof is replaced, and then when the panels are done, they’ve got to be landfilled....
