[RE-wrenches] Interesting Dust Issue

Esteemed Wrenches,

I have an interesting issue with one of my installations.  This is the
message from the customer:

"I use the barn roof for rainwater harvesting, too. The first rain after
installation left my wire mesh strainer clogged with a fine powdery
material. I assumed it was debris from installation. The next rain gave the
same result. I assumed it was pollen as I have for each rain since. HOWEVER,
the roof has two sides and it is only the south side, with the PV panels,
that clogs!"


The site is in an agricultural area and the barn has a metal roof.  We
completed the installation about 6 months ago and he is still having the
issue.


My first thought is that it is related to the doubling of surface area since
pollen could accumulate on both the modules and the roof surface below.


Any suggestions or thoughts would be great.


Thanks

Max
