Tesla powerwall

[Exfarmer]

Does anyone have a power wall?
Experiences?
cost etc?
Any other makes to recommend?

With regards to price, each installation is different, but around £8,500+VAT would be a good benchmark to use for a generic set-up.

Unfortunately as it’s a product in such high demand at the minute, availability is currently looking like it’s around 6-8 months away.

@ajd132 has one - according to another thread.

Personally, I can't see the numbers adding up - under 15 units of storage capacity, so max of a couple of quid saving if you can fill and empty it at the right time of day. £9k spend to earn £600 a year - what am I missing?

Smug factor.

My maths worked out the same as yours. Biggest plus point I can see is whole house uninterruptable power supply, but it a very steep price to pay for that luxury!

I just can't see how it stacks up- over £8000 to store 13 KWh worth, being generous, £2 worth of energy? If you want to save energy, buy insulation or a fuel efficient car.

It's a tech gadget for rich idiots really.

Seriously, are my sums wrong or something? Our biggest expenses on energy would be fuel for the car, the boiler and the wood burner. Our electricity bill is 5/8ths of fudge all.

It’s abit of a toy admittedly. The whole build is very eco though it’s just below passive house level, ground source, solar etc. Would like to add a turbine. It will be great when batteries get better and we can store loads of energy from different renewable sources.

With all new inventions/developments you have to go through the rich idiots toy phase, it is part of the process that brings them into the price bracket that us intelligent paupers can afford.
I think we should all applaud the rich idiots such as ajd132 for taking the plunge.

You could equally call everyone with Aga’s in draughty old farmhouses idiots. Like leaving your car running all night in order to burn toast and cook a mutton and parsnip stew for 34 hours

Don't have an Aga but the Rayburn costs about 2.50 per day which I am quite happy with.

My parents have a rayburn in their draughty farmhouse!
Something like that in a new build eco house would be somewhat ridiculous though.

My hydro handles most things except for the bedside clocks, they don't keep time, and the washing machine. Works alright but when the water heater comes on its computer throws a wobbly and switches on and off every half second. The old machine worked fine.
I don't have the electric cooker and the kettle connected 'cos it isn't always able to take the peak load. I have wondered about a battery to handle that.

What is hydro do you mean from a river?

No, anyone with an aga is an idiot who should never nave listened to the woman in his life that made him buy and install the thing.

If I wanted something that burned oil 24/7 I'd buy a series 1 landrover and leave it running all the time.

Not that eco if it's got a big wodge of un-necessary cobalt and copper sitting in a box depreciating. Eco should be measured in lifetime resources, including the construction.

My house is eco because it's been around for 300 years, had only essential resources/ upgrade spent on it since that time and is heated for a few gallons of chainsaw petrol and some Mars bars for the idiot who cuts the wood (me).

I only cut down timber that is over growing in hedges and if I didn't chop it up the farmer-friend I get it from would merely burn it all in a heap in the field to get rid of it!

Some sort of energy store to smooth the supply and demand would be quite sensible, I'd think. Would probably prolong the life of your water heater computer and all the other things too.

I plant small trees, and gather up an equal number of big windfalls. Although recently the windfalls have been a bit less frequent - down to under five years of stock at the moment so might need to go looking for some birch 'weeds'.
