If I understand your description correctly, you mounted the laminates directly to the treated framing into a bed of silicone?
If so, you may have some release issues over time.
I have experience issues with silicone adhesion to treated lumber on unrelated projects through the years.
Also, I assume you allowed for expansion/contraction of the framing members.
I hope I am wrong about the silicone adhesion issue.

a high quality outdoor paint may also help prevent the warping possibilities.

All that wood is going to warp and twist and bend, as it gets wet and dries out. It's treated, and won't rot, but exposed, you will have pretzels in 3 or 4 years. Or else treated wood has gotten much better in the last 6 months.

I would use Unistrut instead of wood for a DIY panel mounting system.http://www.flickr.com/photos/nsaspook/4694617830/in/set-72157622934371746/http://www.unistrutohio.com/pdf/unistrut-catalog-16.pdf
It lightweight and will last as long as the PV panels.http://www.unistrut.com/

I would be concerned about the heat generated below the panels, that the collective radiation might be held by the earth directly underneath, creating a micro-climate, drying-out the underside of the wood faster than the top side.
In my application, am leaning towards a pole mount I saw in HomePower magazine. Unlike Travis, I am not a carpenter, so I'd prefer to pay for a kit.
I am looking forward to the video brandywine mentioned. It can't be worse than Sunelecs'.
