I didn't think it was at all expensive. I don't know how much the panels would cost to gather enough energy for a house, but the $3500 for the battery would be paid off in 12-30 months, depending on the size of the house. I don't recall any mention of how long they'll last, but so long as it is 10+ years, there would be cost savings.
How do you figure this would be paid off in 12-30 months?
It's $3,000 for the smallest battery they offer. Then ~$2,000 for a DC-AC inverter, not including installation and the cost of panels. This is for continuous 2kwh that is about enough electricity to power a single microwave.
From Agrul's link:QuoteAnd if you don't already have a big enough photovoltaic system to get off the grid, paying the estimated $0.30/kWh for electricity through the Powerwall may not make much sense. On average, grid prices for electricity in the US are about $0.12/kWh. Rooftop solar PV is estimated to reach grid parity in most places by 2016, but it's not quite there yet.
$0.30kWh is three times as much as I currently pay for electricity on the grid.
I'm gonna stand by my assertion that this is expensive. I'm sure it will drop more in the future and it's not terribly far off from being economical, but right now I think it's still in the "toy for rich green advocates" category along with their cars.
