So I'm getting that you're currently paying about $.09/kwh through TVA? But they'll allow net metering for $.12/kwh? I can be certain that at $.09/kw (similar to what we pay here) that your payback calculation is going to be WAAAAYYY out there. How much of your total usage would you like to offset? I ask because I recently went around the house taking readings and doing the math on what I call day-to-day usage, the normally used lights, appliances, etc. (without factoring in A/C or heat). I say this because although I acknowledge that not only have PV prices fallen dramatically, and system efficiency has steadily improved over the years, you'd be shocked at just how little power these systems can effectively produce to offset your current usage. Not sure where you live in TN but amount of overcast skies/year and daylight hours and sunlight angles have a huge bearing.
Jesus I sound like a lobbyist for the petroleum industry. The reality is that I come from the electrical industry and I'm a huge proponent for solar and wind technologies. I've been where you are for the last couple of years, but after putting pen to paper and doing the math, it's a longshot, especially around here where they won't allow net metering! GRRR!
