Solar panels will always work in cloudy weather. I’ve seen similar efficiency to sunny days, in fact you might not even be able to notice the difference unless the panels are truly covered by rain, hail, snow or dirt from a dust storm. So, this does not entirely dismiss the idea that solar panels do need to be clean, and 100% visible to incoming light to produce their fullest efficiency levels. However on the flip side fire season could be damaging, because the opposite of cold weather, excessive heat is actually quite damaging to solar panel efficiency ratings, which if too hot can drop by about 50%.
