I seem to fall into this category: "If you have no local industrial polluters, but have regular rainfall—*and your PV modules are at a steep-enough angle to allow rain to wash down the glass*—the effects of soiling on the system’s output could be minimal, and not worth worrying about. "

I washed 2 of my panels after the first 12 months, and 6 months later you can hardly determine which two I washed looking at daily microinverter outputs. Used a sponge mop on them even... Today was a beautiful solar day, and I collected 1.25kWh from two adjacent panels (one washed, one not). I collected 1.28kWh and 1.27kWh out of two that have never been washed.
