@Crucial interesting stuff. A few bus fleets are looking at retrofit of gas-electric setups as well
Wife has a car with her work, and the fleet contract is up for renewal. I've told her to tell the fleet manager to sign a short term deal so that they can wait until Tesla is doing the Model 3 in quantity next year

Of course, the upshot of going full EV on your fleet is that electricity retailers now need to find you some more juice.
On-premises parking with charging stations could help offset solar / wind spikes, which the big generators see as a genuine threat to the system: fluctuation of power.
There is a persistent belief that, because our grid is built to handle certain frequencies (e.g. 50Hz) in order to make sure things don't blow up down the chain. However, with a big enough battery and inverter you can mitigate that.
The other side of it is the Duck Curve, which I cover here as part of a thing I entered.

500-700 words was a little limiting for my frothing enthusiasm, but the basic premise is the same: the industry needs to undergo change.
Baseload isn't even a thing if you ask the Chinese. There is a technological answer for anything.

@NTA said in Solar Power and Storage - a nerd's view:
Effectively, yes. My power bill for the year prior was about $2300. This year it will be (total including all fees and referrals) approx $280.
Oh. I just realised that I'd miscalculated something there.
My actual out of pocket for electricity bills this year:
$175
So I guess all the haters - who said "it's not worth the money!" - can tuck into that bag of steaming cocks they no doubt keep in their pantry.

Those tariffs ended in NSW and SA this year. And the conditions on the QLD ones are quite interesting - can't move house, can't alter the size of the system.
The state government were simply too stupid (or uninformed) about how, once people saw what they were getting for the investment, they decided they'd never move house.

So without having to read/endure your blog. What's the short answer here on investment payback. How many years now you have some actual results to work off?

It would be 9 on the full price of my system. But under 8 for what I paid.
However, the new powerwall would chop it down to below 7 even at full price I reckon - more storage, more output.
As I've said before: savings not ALL in the battery, but spread across the whole system.
Everyone could probably save 25% off their bill right now if they looked for a better deal, and took some efficiency measures in their current house.

Not all of us would get overly anal on saving power though as well. For example those still getting the occasional bit between the sheets may be happy for the missus to use the oven

Awnings over particularly hot windows don't cost much.
Knowing you can run your air con at 25C instead of 23C without dying.
Getting TOU power and putting as much heavy stuff as you can there.
Going and getting a better deal - and understanding how you pay, and what that actually means - is the biggest thing. -
@dK yesterday was $2.57 (out of a predicted $2.95)
Today so far I've been alerted to dispatch $2.45 (2.54kW) to help support the grid. Started about 1715 hours but I had the air con running so might not make all of that.
I've been following the NEM on Twitter the last few hours. The situation earlier today - predicting blackouts from 5-6PM across NSW - has eased.
Also this from AusGrid:

I set my aircon to 25 today. Suffering like a peasant.
Thank fuck for the pool and the students/ diplomat daughters who live here...

Another dispatch requested for $3.20 at 1801 hours.
Wife just got home though so air con probably happens now
Just a thought. Have you run the numbers on efficient use of your aircon? trying to cool a hot house can crank through power whereby keeping a house from getting hot in the first place can be more efficient.
