Rooftop solar is usually the homeowner's decision, and it is simplest on a house with a roof of its own. In Naples, 82.1% of occupied homes are lived in by their owner and 31.2% of all homes are detached single-family houses. Condos, townhomes and apartments usually need approval from the building or association first.

Half of Naples's homes were built before 1983. Panels last decades, so if your roof is near the end of its life, ask installers whether to replace it before they install.
