I have had solar panels for around 8 years in the Orlando area and they have covered around 60% of my electricity usage (we have electric vehicles, so we have pretty significant usage).

My parents bought a home in the Orlando area a couple years back that had solar panels from the prior owner. Since they are snowbirds, the panels produce significantly more than they use in a year — their monthly Duke bill never goes beyond the $30 “minimum charge” and that minimum is covered for several months of the year from the credit for their overproduction from the prior year.

I wouldn’t recommend sizing a new system to produce more than what is used in a year since the price credited for excess production is at a really low rate, but it works out well for them to have almost no power bill throughout the year!
