Yes, recessing the array into the tile by removing tile and putting down comp. roofing under it is a nice way to go. Definitely costs more, but looks very nice and this can make it worth it. An on new construction is less expensive as it saves on tile cost.
My biggest concern would be the heat build up. If it is recessed, there is no air circulation under than panels. The higher temperatures are going to significantly reduce your efficiency, and most likely lead to higher failure rates.

+1. Temp. will likely be higher, lowering efficiency. Panel life and long term efficiency may and probably will be affected.
