dustysmurf:

gzt: Recently replaced gas hob with induction hob.
During the selection process I learned a lot about induction hobs. They don't need to consume more power than a standard electric hob.

Can you provide details of what induction hob you went for, as i'm looking to disconnect the gas, so what to replace the gas hob with induction, and gas hotwater with heat pump.

But I want to do the entire switch with solar panels install, batteries, and 8-10K hybrid inverter at the same time.

Also, thank you to everybody that shares their quotes in the solar thread, And what inverters they end up going with (or upgrading from/to)

IIRC the break even period will be about 10-15 years, probably shorter as I am expecting an energy crunch at some stage that will drive up the cost of power.

And that will drive adoption of solar and batteries which are not worth it for most people so IMO ends up being a positive outcome.

The issue is NZ is a tiny dot on the butt end of the world.

When we want to go mass renewables then other bigger, wealthier countries will be wanting to do the same.

Last year china install MORE renewables than the entire USA currently has, and they are ramping up.

Yeah, but the electricity market is not a world one like oil and to a lesser degree gas is because its not exportable. So if the rest of the world still have cheap power it will not push the production of solar gear up in price. We will just have to deal with excessive margins from the importers and installers like with everything else here.

Australia is been involved in a plan to export electricity via undersea cable to Singapore

Depending on your exact household set up and energy use, the more conservative government calculators estimate between 7 to 12 years for break even at current prices for solar (without battery).

My new build is 100% electric. Hot water cylinder, ducted heat pump, induction cooktop and an EV. The two of us are usually out during weekdays at work so we're on an EV power plan that gives us great off-peak rates which also apply for the full weekend - our monthly power bill is around $300. I also have some automation that keeps the hot water cylinder turned off during the peak periods.

I do live semi-rurally in an area that gets snow occasionally during winter, so the plan is to add solar and battery storage in the near future to secure against power cuts. We did have one power cut that lasted around 8 hours during a winter storm soon after we moved in and while not being able to cook food was a nuisance, the house is so well insulated that the house stayed very comfortable the entire time from the heat the heat pump had generated prior to the cut. If things started to get unbearable then we can sit in the EV in the garage and use it to warm us.

I have noticed some of the neighbours in my new development have installed gas and rely on bottles, which depending on timing, could also be an issue during a severe winter storm if they run out and the delivery truck can't get through.
