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.
