It is a good question. If these things collect snow they will be basically out of service. I suppose regular dirt also cuts the output too. I guess in the end it will be a cost benefit thing. We figured these things generate about 22 cents a day (retail rate) How often can you send a guy up in a bucket truck to get the last nickel a day out of them and still make economic sense?
I suppose you could come up with a squeegee and sponge deal on a non-conductive pole so these could be cleaned from the ground. It might be a make work job for about 250 people if you cleaned them once a month.
