I dont see your 7 cents. Looks to me like you pay $139.70 for 1052 kWh - or 13.3 cents. You gotta pay for getting it there, plus a bite to taxes. And also there is that little line that said you were paying 12 cents, before taxes. Cant just take a line out of the middle.
Sorry - looks like I piled on - should have read the posts below yours and not repeating the blast.
Holy cow you guys pay a lot for power. ~ 2.5 cents/kWh here in Colorado.
Why do you amortize over 10 years, when the system is likely good for much longer ?
I haven't read anything about side loading packs - and don't see mention of it searching back through Dec - can you elaborate/link please?
From the Tesla video of the semi showing the individual components, the sides of the battery packs are the only locations without frame structure. So it looks like they slide in from the side.
So I just posted a few of the details, and rounded at that. Buying 7.92 kW system that replaces 96% of my estimated future consumption, and Net Metering rules prevent me from going higher, even if future consumption increases. $2.42 /w of installed capacity - that drops to $1.55/w after a bunch of rebates. Warranties for for various aspects start at 5 years, have 10 year, 12 year, 25 year terms, depending on what feature is being looked at. This from the vendor I selected. Looked at 6 vendors - got various panels, inverters, microinverters, and contractor warranties. To have a common basis for price comparison, I ran a Present Value calculation on every aspect at 10 years. I picked this common denominator because that is how long of a guarantee I have on my life. [right - like I really know when I'm going to croak]. I did not put into this evaluation financing cost, or alternative investment opportunity cost. I did not insert any dollar value to the "save the world by going solar" or any feel good aspect to the investment. Somebody will buy my house from my widow and pay something for the increased value of hardware on my roof. By running a PV at 10 years, I don't have to guess what value that may be. I needed some number to compare against the do-nothing option and continuing to pay the $/kWh that my supplier charges in a complex batch of rate options, that are always in their favor. Bottom line - I pay 14 cents to TEP or 4.7 cents to my self. <== exactly what your Ballpark was. I achieve a 8.8 year payout against today's rate structure. Not a great investment, but not a bad one either. Wish I could tap into Tesla 7 cent mega-chargers and pay that rate for life. but, then that reality thing happens.
Thanks for sharing.
