Telsa Energy Plan
« on: May 18, 2022, 07:07:25 PM »
Anyone on board, if so opinions and thoughts please.
I'll be connecting a PW2 shortly, and am a tad undecided.

Why are you getting a powerwall?

To store power, what else.
We generate enough kwph during the day to run the house and fill the battery, which will allow heating/ cooling to be run 24/7 at no cost.
But reading the Tesla plan, although the $ are attractive, they have the right to drain the battery down to 20% overnight (to feed the grid) up to 50 times per year.
Seems to defeat the purpose.

How many amp hours are you getting with the pw2?
I have a mate at work who has a pw1
He said that he tried it with everything connected and it went flat in about 3-4 hours
Now he only runs a select few circuits
Lights and fridge I believe.

We use about 7 kwhs in summer and generate about 30 on Ave.
Winter generate between 15 to 20.
PW2 holds 13.5 kWh.
Any access goes back to grid.
Anyway, anyone on the Tesla Energy Plan please?

Pw1 was only 6.5kw from memory, that why.

It's the first question we ask when customers want a quote.
Some people want them for grid outages, some want them for bragging rights, some for as you have stated, and others for the fact they think they will make money.
Generally the pay back period on a pw2 on average we find is around 12 years.

I doubt we will get ROI, went In eyes wide open there. Our kids will benefit when they sell up eventually.
On retirement plan was cash for everything, no more loans. new car, new house architect-designed to my specifications built by a proper local builder, new everything, tv, fridge right down to all furniture cutlery and no debt at all and as few bills as possible.
Very close to achieving it all.

So who owns it? You, or them??

The cynic in me wonders if 50 times per year becomes 100 times per year, then eventually whenever they want.

We don't have a battery yet, and haven't looked into it, but I reckon I'd be looking for one without conditions.

Yes, agreed, already gave that the flick.
When the sun goes down I want that battery full.

Home batteries don't pay and with the price of lithium battery resources climbing with scarcity and demand they likely never will. You're better off investing in max solar panels for your roof and using a solar diverter to heat a large (400L?) resistance HWS-
https://www.powerdiverter.com.au/products

Heat pump HWS don't cut it unless of course the taxpayer helps fund them and solar FIT is headed for zero with the solar duck curve. The future is an all electric household (induction hob LEDs etc) and use it yourself as much as possible or lose it. Storage HWS as well as airconditioning the home for your return is the cheapest form of storage and the taxpayer can't keep funding all of us in a zero sum game. If Gummints continue to print the money for it we just cop it in inflation in the absence of taxes to balance budgets. You can see that right now with all the global Covid helicopter money.
