I recently looked at what would be involved in getting a rooftop solar array approved and installed. The regs here require approval of plans by the local electric utility monopoly, specify net metering, and selling excess power into the grid past the home's monthly usage (negative net usage, feeding the grid on average) pays ~1/4 the cost to purchase power from the utility, provision of documentation to the utility and IIRC local government, etc. Liability insurance is also required; no idea what that costs. Coverage for hail and wind damage to panels may vary. Adding lightning rods and other protection might be advisable, since a panel array and its framing is a big electrical circuit on top of the house.
