"It's certainly not true for places like where I live that are running 6.5-cents/kwh."
Does that include all distribution fees and taxes? Because if it doesn't then your parity rate is likely closer to 10 to 15 cents, which is about the current going rate for large scale PV. Residential it's higher until you remove the price of a roof job. Still not parity, but not far.
Yeah, if you roll in the service delivery fee I'm at 7.9-cents/kwh.
I have trouble believing a estimate of 15 cents/kwh as the going rate for large scale PV. The lowest estimate I could come up with for lifetime cost per kwh on personal solar setups was 22-cents/kwh. I'm going by the calculations at http://www.nmsea.org/Curriculu... and using a much lower panel cost of $2.50/watt (versus the 2013 cost numbers they have) and assuming similar costs for the install labor, batteries, etc. Those calculations leave out some important things though, such as 1 or 2 battery replacements over that lifespan, maintenance/repair, sales taxes, added homeowner insurance costs, and what the upfront cost would have earned if it had been invested instead. I'm not sure 25-years is a reasonable lifespan estimate for chinese made panels.
With efficiency improvements expected within the next few years, I feel people would be better off delaying and waiting for better panels to come on the market.
Too many people are focused on the panel cost per watt coming down, but not understanding that's like trying to use gas mileage to estimate cost per mile. You need to account for installation cost, insurance, maintenance, depreciation, lost interest by tying up the money, etc. So while the car might get 10-cents/mile based on the mileage,it might be closer to 30-cents per mile once you figure the true cost.
