[RE-wrenches] Ballasted Roof Racking Recommendations?

[R Ray Walters]

Sunpower has just that.  Very easy install, no grounding issues, super high efficiency. Downsides: expensive, Plastic, finicky layouts from their engineers that preclude using it on smaller roofs.

 I would use it again for a larger roof that needed to max out the output/ sq ft of roof.  It's probably the best commercially available module in the world, definitely the most efficient.  Last I checked it qualified as American made, though some of it is made in indonesia I believe.
