@nta Thanks Nick, that's an awesome, useful post.
Getting me to shut up about it is the challenge
I've got a battery that is 6kWh or a bit less now it is getting on a bit - that handles about 80% of our overnight needs but we also have gas hob and hot water so that is a factor. 2 adults, 2 teens (17 & 13). Average consumption of 20kWh / day across the year.
I think if I had a 10kWh battery that would move it to 95% of overnight needs, weather pending.
Oh another thing: smart home control can also extend to devices like your car charger. If it knows when you have excess solar or offpeak power available, it can use that rather than peak grid tariffs. My battery has a smart controller than can pull in cheap power overnight, for example, and apparently it is EV-ready.

Yeah, we have a smart meter & we have a smart car charger (with no car to charge, yet) which are linked. The guy who installed it who got me talking about solar panels said it's amazing the number of people who charge their cars at night who have solar panels.

Last time I looked at solar in NZ you couldn't sell the power back so it was pretty useless, plus I'm old so will probably die before i get a return, plus it's highly likely I will move homes or be away travelling for much of the year so....
I could do it for the good of Gaia I guess, but I have to protect my boomer reputation.

@dogmeat Here in Oz, when the first solar schemes came out and offered 40-60c per kWh exported, boomers were the first to jump on board.
A system back then was like $20,000 for 2.5kW, but if you turned your shit off during the day you could export way more than you imported.
In NSW with 60c export, and roughly 23c import at the time, it was easy money if you had the capital.
Those schemes are gone now, except in e.g. QLD where you got 44c export if you never increased the size of original install, and didn't move house, with a hard stop of 1 July 2028. The result: people who installed solar systems prior to 2012 paid for them inside a few years and everything after is gravy. For over 16 years...
Government seriously underestimated the resilience of people to stick with the same sized system and address, actually believing that people would move house every 7-10 years...

We've just ordered solar with a 10kWh battery on a 5.8kWh system & a diverter to use any excess power to heat our water. It's going on a SSW facing roof. I have a personal weather station and we've used a year's solar energy data to model our savings. We'll be energy self-sufficient from April-mid November and around 60% for the rest of the year.
The big issue is the return on your investment. I think that will be around 7.5 to 8 % which is payback in around 9 years - earlier if I go for an EV in the next few years.

This was last month and I'm starting to think that a battery could make sense given how much energy I'm still pulling in from the grid

Just remember that an Electric Car has around a 60kw battery inside of it. In theory if your car can power your house and act as a battery, you may not need a massive home battery. Of course, it depends how often you use the car, but I see that as an obvious solution for many going forward.

My provider mentioned the same thing when I had the system installed. The major stumbling block is the car probably isn't going to be home during the day.

Have you thought about moving into the energy/utilities IT field? the analysts used to get paid a bomb (not sure about now) and you sound more knowledgeable than them (well the ones I worked with).

I kind of work parallel to our company's energy team in the data area from the corporate consumer side. I thought about going fulltime into the energy bit but got lazy
