I was born and raised in Tampa. The article gives no real numbers. What make and rating, how the panels are grid-tied, etc. My guess is that the seller lied and used the name plate rating on the panels, which is a bs number. It also doesn't say how often the panels are cleaned. The dirty salt air in Tampa would cut output quickly unless the panels were kept clean. I had a family friend that lived in Apollo Beach and their cars were covered in ash fall from TECO's coal burner across the bay.
The article also doesn't say how the panels are angled. Mount them flat and they will cook if they are mounted below the roof line. Temp matters a lot if you are using amorphous. The article suggests they are because it says they can produce power in moonlight.
It sounds like a scam based on "free" federal gov't money. When you're spending your own money you tend to be more careful.
