I am also sure that electric costs will continue to increase so the actual savings over time should be even more.

If you are an expert respectfully, you are one who failed mathematics. 55% of your electric consumption is HVAC. You do not need to speculate on that percentage. There are dozens of studies that confirm that or you can simply monitor your own consumption by a device that takes 100,000 measurements of your electrical use per second, that's 8.6 billion times a day, I'd say that's pretty accurate (
Home - Sense.com). I've one and 55% of my electric consumption is HVAC.
So we know in Florida not every month is a cooling month. Let's say it is precisely ten and the portion of your bill purely for kilowatts is $250.00 or $2,500 annually of which $1,375.00 is HVAC.
You are claiming $200 to $400.00 or 14.5% to 29% can be saved by the installation of a solar fan.
If you have facts to support this then you, Sir, are wasting your time here, on TOTV, and should immediately contact Jennifer Grandholm, former Governor of Michigan and current US Department of Energy Secretary. But, in your own interests do protect yourself. I recommend that you find a way to capitalize on this ground breaking energy savings.
Perhaps, I am not giving you credit for altruism, are you the energy equivalent of Dr. Jonas Salk (inventor of polio vaccine) and you are providing this ground breaking version of energy conservation for the good of all mankind without profit? If so then godspeed sir! And thank you!
