I do what I can to minimize trash buildup, but…
…trash does build up, and sooner or later it has to go somewhere. Since I don’t (officially) drive, and I really don’t drive (on pavement) so much that the prospect of doing so in an unsanctioned manner makes me nervous, the logistics of this became complex. And rather more labor-intensive than my aching back thinks is quite right, but tomorrow morning all this junk is going away.
Not sure why you’re throwing away the solar panels. Their output may have gone down, but they still generate power. You might have to fiddle with your strings, depending on what kind of solar charger you have, but as long as each string adds up to the same voltage it will work fine.
Assuming of course that you have equal numbers of good vs weak so that you can put a good and a weak in series in each string.
