Any of you installers ever consider (or achieve) a PV array installation atop a topless concrete silo? Any and all thoughts/comments/suggestions welcome!
If there is a way to attach mounting rails, and then to attach the PV to the mounts, it should be just fine. PV's don't really care what's under them. The Silo contents may care, if it's explosive grain dust or something, you can't just string wires up, still should have permits, inspection.
When PV's aren't parallel to a roof, you have to watch for wind getting under them,
like a big sail, you don't want $20,000.00 worth of glass to break loose in wind, and go blowing all over the countryside

Sorry for the off-topic post Kris, but was that NABCEP certification hard to come by? Did it help you a lot in your business? I was just looking at your website, very cool..
NABCEP certification (or active pursuance of) is required for the state funding program in Wisconsin, so it is invaluable to my business. The test is very difficult and has been failed by many unsuspecting electricians. I studied for a month and did pretty well. Historically, one problem with the solar industry has been that there are many organizations out there claiming to train and certify solar professionals...some good and some not so. NABCEP is developing a good reputation as the industry standard.
