So Alexander, did you decide to buy the Powerwall? What was your final decision? It would be awesome if you share a little info. ;) But it is up to you, if you don't feel comfortable with it, it is fine.

After I carefully examined everything, I decided that I will not buy a nissan leaf. I know that this might sound "stupid" but Elon's opinion on this passively cooled battery technology is the main reason. Here in Florida it can get really hot. I will wait for another car, maybe a ford ev, which...

Thank you so much for all your answers! This is so helpful! I will definitely reconsider everything and look more closely at all the details. I was not very familiar so far with potential problems. Back in 2011 I test drove a Nissan leaf for the first time and was very impressed with the car...

Hi Guys! I am thinking about selling my Prius due to Battery controller problems and other issues. I am thinking of switching to a used nissan leaf for 9000$. A great deal in my opinion. I am familiar with the bars indicating the battery health left and it looks not too bad. Since I do mostly...

Please someone ask!!! xD All stupid questions on there. -_-

You are right with every point. You rightfully compare probably a luxury sedan with a Model S. I compared it with a compact car. You can argue that this is not fair and I agree. But you have to calculate the cost of storage and PV (?) solar energy production. This is not something no one can...

Great Post! And thx for all the responses. Very interesting to read. I made the very controversial post on purpose. -> There is a clear paradox, which must be solved. <- In order to get more EVs on the road we must have cheaper electricity rates. But the electricity must also me clean...

I tell you why I will never drive an EV: Gas Price: 3$/Gallon. My Prius: 50mpg EPA, 40mpg Real world. -> 0.075$/Mile fuel costs. Nissan Leaf/Tesla Model S: 350Wh/Mile, 450Wh/Mile Real world. 20% Charging to wheel efficiency loss (assumed) -> 540Wh/Mile. -> 0.54 * (Your electricity rate, Mine...

They can withstand the winds, but not heavy debris. If there is a leak in the roof, I have to take them down at my expense and put them on again (happens more often than one would think). Solar inverters fail more often due to more frequent usage than a backup system. There are generally no long...

Yes, if I could I would buy a generator. And 3500$ is hardware only. 3640$ for inverter and installation is acually quite affordable if you think about it.

After closer consideration I decided to buy the Powerwall for my house in Florida. We don't have a natural gas service, so a generator is not an option. Solar is not an option due to hurricanes and low energy prices (12c per kWh). I will likely buy the 10kwh battery from solarcity for 7140$...

The prices don't increase, the euro looses value. Big difference. If you want a stable currency, switch to the dollar. Internationally everything is traded in dollars.

WOW we in Florida pay a flat 12c per kWh. Thank god we don't have too much solar power and a great and reliable utility company (FPL). You guys in California are quite crazy people. We down here burn coal and natural gas to enjoy a nicely cooled home and heated pools (and we soon get a new...
