I went with a residential, snap together, standing seam roof approximately 15 years ago. I did it myself, so the cost wasn't too prohibitive. Later I installed solar - very easy with the available clamps. No roof penetrations, except where the PV wires are combined & sent down through the attic to the PV disconnect. One thing that I would definitely change would be to use a lighter color. I used a forest green color, and while I love the color and it goes with my wooded surroundings, it does not reflect heat as well as a lighter color, and it is beginning to lighten up - it is not as bright green as it was. And yes, it was the premium paint finish, kynar, I believe.
As others have said above, go with metal. If you use a good quality metal, you'll never regret it.
Edit: AND, if you went with asphalt, you WILL be replacing the roofing much, much sooner than with metal (maybe never have to change out). What are you going to do then; try to stictch in replacement shingles around your panels? R & R all of the solar install? What about the ya-hoo roofers up on your roof working near your solar installation? Don't chance it, use metal or use a ground mount install.
