Dan,
I remember reading some REC material regarding cleaning
panels and they we very hesitant about anything brush or sponge-like to
clean their PVs, though I too, for my own arrays have used a car-washing
brush (very fine and soft) to carefully remove scum. It seems it may be
the only method for getting off hard-core crud.

Bill; Similar situation in my area (CO) from the big fire that went
through here last fall. Some had enough water onsite for the sprinkler
trick, but the biggest issue was thick coats of pink fire retardant
from the slurry bombers.
The only thing I could find that worked on both the ash/mineral scum
and the pink slurry was.....dish soap and soft scrub brush. And LOTS
of brushing, 3-4 times over all my PV arrays. I was hesitant to try
anything stronger, like Simple Green, and tried to get info on that
and other chemicals from a couple PV module manufacturers, with no
success.
Good luck!

Dearest wrenches,
Trying to get back in the saddle here in the Plumas
Natl.
Forest...We are just coming out of 7-8 weeks of threat of fire
from the
Dixie fire in NE CA....has been life changing, three of our
communities
were lost or severely impacted.
But many of my customers did the old "sprinkler on the
roof" trick and left for evacuation so much ash and (well)water on
panels for weeks at a time. Depending on a variety of factors some
folks have not been able to see the PVs clean up with a simple water
spray and I've been very hesitant to recommend anything like soap,
soft
brushing etc. Will the eventual several inches of rain remove ash
and
minerals left from well water?, its pretty backed on.
I'm looking for proven suggestions and/or
experiences. No
structure loss here but fire took part of our trees/property. Of
course
some of the system arrays are easy access and some are on two
story roofs.
Thanks,
Bill
