The pity being that rooftop solar systems trip out in the event of an incoming mains failure as a safety precaution. Otherwise they will backfeed into the grid and cause a safety issue for power line workers as lines they expect to be dead will still be live.
It might be possible to design out and have your home system island itself but I bet that the cost would be significant.
