Tesla powerwall

[Guest David R]

What are people's thoughts on it?

I will be getting one depending on what they charge for them here. Electricity in Australia is quit expensive and this will help offset some usage charges combined with a solar power system

By the time V2 is launched, which is when I would jump in for our house, my solar feed in tariff will be below what I purchase power for ( currently it is almost double ) so I'll look at it then otherwise it will be costing me money

We are however off grid at our shack with solar, wind, small diesel gen ( which has only been run for maintenance ) and an old school battery bank. I'd jump in instantly there if the batteries were to die .. currently I house about 15kWh in a 9' x 12' shed, have to constantly drain and recharge and top up battery fluids. You have to hand it to Mr Musk, it's certainly a hot seller and a very neat package. Liquid cooling is a bonus too for us here in Au, giving it I think 43°C max operating temp, so it covers all but a handful of days where I am.

 

I think personally the biggest change is likely to be how it changes the power industry, making them more accountable, and putting the wind up them. I expect, as recently reported here, that power companies will get as big a shakeup as all the bit players coming into the mobile phone markets gave the big telco's, along with the subsequent pricing plans and benefits that competition bring with it.

You are one of the lucky ones Al with your FIT. I built a house last year and we are on 6c FIT. We currently have a small system but will be looking at a larger system when batteries become more affordable

Here in Denmark the Government is financing windmills by taxing electricity extremely hard (We basically pay 0.05€ for a kWh, but then we pay 0.20€ for all the tax). This was offset previously by the way solar panels were tariffed - basically, the electricity counter would count backwards when you produced more than you consumed and fed it back into the grid. Only when the production went above the total consumption would you be lowered to a lower tariff (approx the same as the cost price for electricity sans the taxes). But the problem with a socialist government is that at some point they realize they are making too little money off you, so now they've changed the system so now they've lowered the tariff significantly (to about half the total price).

 

Therefore, hybrid solar systems are already being sold in Denmark - however, these are made with Lead-Acid batteries and the batteries, though being deep cycle, only last three or four years before needing replacement. So I could definitely see the benefit of getting a solar panel set hooked up to a Powerwall as this will probably be more durable than the L-A batteries currently in use.

 

But if you don't have a solar panel system, it probably wouldn't make much sense here in DK At least, as we have the second most stable grid in the world (after Norway or Sweden I believe, so as a UPS it doesn't make much sense - and there will be issues with some electric equipment if you run your entire house directly of inverter-made AC as it can't make the reactive power needed to magnetize coils/wires.
