class=500432319-24112012>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 (<A
href="http://www.solarframeworks.com/powerboost/">http://www.solarframeworks.com/powerboost/</A>)
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.</SPAN></FONT></DIV>
