[quote=ocrenter][quote=AN]That’s the same thing, right? Either you sell it back to the grid or have enough to cover your peak usage, either way, you’re storing and purchasing at $0.17 and use/sell at $0.48. It would take ~23MWh to break even, assuming it cost about $7k installed of the 10kWh powerwall unit.[/quote]
Oh yeah, of course. It would be similar selling back or using the credit.
Powerwall install cost is crazy. $4k just for install? And of course solar city will have monopoly on the install. That’s the Tesla way![/quote]After doing many projects around the house, the safe estimate is installation cost = cost of materials. So, my guess would be $3-4k. That’s not too crazy since installation of solar panel is 2x that and the process isn’t that much more complex.
I just thought about it and realized that this buy at $0.17 and use at $0.48 only apply during the summer. During the Winter, it’s buy at $0.18 and use at $0.21. So, the math would be much less favorable 1/2 of the year.
