    due mostly to the substantial divergence between nominal "installed capacity" and the actual 24/365 production from that "installed capacity".

    In addition to "availability" issues there's durability/servicability issues . . . what is the expected lifetime of a roof, or especially of roof-mounted "accessories", in hurricane-prone South Florida?

    Fake Left, Drive Right . . . not my idea of a Democrat . . .

      Installing insulation in buildings, replacing old appliances with new, energy-efficient ones, and installing solar water heaters would be even cheaper and more effective.
      The Florida Office of Energy reports that:
      Since the adoption of the Florida Energy Efficiency and Conservation Act (FEECA), Florida is expected to reduce its need for new generation facilities by 6,500 Megawatts and reduce energy use by 7,500 Gigawatt hours as a direct result of the utilities’ energy efficiency and conservation programs.
      I don't know a whole lot about this efficiency program, but I'm sure that a more extensive second round of the program could produce as much savings again. 6,500 MW of avoided power capacity far exceeds the 860 MW that Crystal River 3 produced.

      So then add 275 MW/year of PV installed x 5 years of new installations x 0.84 conversion efficiency converting from DC power to AC x 30% load factor (since PVs don't work at night or near dawn/dusk) and you get 347 MW more capacity roughly equivalent to nuclear baseload. So OK, that's not more than 860 MW, but then again it is electricity when you most need it — in the middle of hot days. And if you mount it on the buildings you are powering, you can cut transmission losses by a lot. And this is in addition to the cheaper savings from efficiency and conservation. So together, you have a lot more power and it tracks your load a lot better at probably a lot lower cost overall. Especially if you include any environmental impacts in the cost analysis.

      By the way, Crystal River is in the northern end of Central Florida (not South Florida) and people have roofs there that stay intact for many decades.
