Liability insurance seems fine -- if the systems and installers are safe, underwriting it will be cheap. What seems to be harder is finding an insurer that will cover you.
You can even tie this back to hurricane season if you wish (since you brought it up)-- given the high winds can cause downed power lines, even when a storm has been downgraded below hurricane, you really don't want energized lines from solar while repairs are ongoing. And given Florida's hurricane frequency outlier status in the US, they may want more rather than less of it. One way to keep people honest about this is liablity insurance. Now it's your job to keep it repaired and the insurer's job to inspect it, since they're on the hook. And if someone is injured as a result of your culpability, neither they nor you are screwed.
But sure, the energy company probably isn't happy about solar subsidies either.
