Great idea.Last year I collected the condensate from my mini split into a 55 gallon plastic barrel. I feed water from the bottom into a small electric Ryobi pressure washer. Gravity feed works on some of the smaller units FYI. I used it to wash off the panels. I was careful to not point the high pressure stream close to the edges where water could be force in. Worked really well. No water spots since it was distilled water. Not going to work easily with roof mount but for panels lower to the ground, a gentle pressure wash is nice and easy.
