Rumours have the 10kWh unit at $13,000... It's a major bummer i was hoping it would be a lot cheaper so it could have some sort of ROI with peak shaving and be a battery backup for when the power goes out as well. I looked at my peak usage over the last 30 days and if I multiply by 12 and calculate the price differential between peak and off peak I'd save somewhere around $160 a year based on current prices. Maybe I could switch to wholesale pricing or something...
And equate to a battery cost of $110,500 for the 85kWh of battery in your car. And I wonder if these batteries will be similar to the one in your car - you would think that a battery for your home could be made cheaper as the energy/weight ratio doesn't matter nearly as much.
Yeah, that pricing is definitely a bummer. I can have a Kohler 14kW NG generator installed for that price. Considering I already arbitrage rates with solar (sell during peak, buy overnight), the only personal benefit I see in the battery is avoiding outages. I'm all for getting one, but that pricing and size wouldn't make sense for me.
