[RE-wrenches] power washers

[Chris Daum]

Nik:
 
I suspect with some modules a pressure washer could cause problems and
possibly damage module's integrity.  There's a product (which I do not sell,
by the way) called PowerBoost (http://www.solarframeworks.com/powerboost/)
which you stick on a hose like a lawn fertilizer squirter; you spray it on
the modules and it foams up, then you rinse it off after 10 minutes or so.
It keeps a coating on it that sheds dirt, dust and bird doo readily.  I had
a great opportunity to test it up here; I sprayed the stuff on my 5.7KW
array early in the summer, then 8 weeks of fire season deposited a
significant amount of dust and ash on the modules.  When I finally drug the
hose up to the third story to rinse the modules off, they were amazingly
clean.  And my array output jumped appreciably.
 
Best,

Hey Gang,

What does the hivemind think about using a pressure washer on solar PV
modules? Any experience or insights would be appreciated.

Cheers,
Nik
