Can confirm, Tesla Owner. I guess living in Texas as well, which has dirt cheap/free electricity. Yes, I have a plan that I pay $0.00/KwH between 8pm and 5am.

Have you run the math to see if a PowerWall would make sense if you can charge for free at night?

  Even if you can charge for free the batteries only have a limited number of charge cycles so you have to pay for the wear and tear on the batteries. Last I heard the economics were pretty close to neutral for the US: From http://www.catalyticengineering.com/top-ten-facts-about-teslas-350kwh-powerwall-battery/ http://www.catalyticengineering.com/top-ten-facts-about-tesl... "So revenue is $1.66 x 183 days x 10 years = $3,000. You’ll just about recoup the cost of the product, but you won’t profit because of two factors – the cost of inverter and installation, and the time value of money. We’re in a low-interest environment, but setting aside $7,000 today to make back $3,000 over 10 years still leaves you down $4,000 – not a very good deal."

    Energy storage is eligible for the 30% tax credit the same as a solar panel install on your roof. So knock 30% off the total install cost ($4500 total - 30% = $3150).

  Not yet. I haven't even bothered as the current gen powerwall is pretty much not for sale... not many people actually got them. And also they are announcing PowerWall 2.0 this month. So we'll see what new features it'll bring and when I'd be able to actually buy buy. Solar Panels are pretty much a no go for me because I have a flat roof top patio across almost the entirety of my roof. Which is dedicated to a kitchen, seating, hot tub and a putting green ;) Also, realistically, electricity is so cheap here, the difference wouldn't make up for it, although I'd get it because it's "cool" haha. I think the flat rate 24 month contract, you can get $0.75/kWh now. Pretty crazy.
