Oceania too: Australia installed 442 MW of residential solar and 2.5 GWh of residential batteries in the month of April alone. Both numbers are partly juiced by changes to a rebate program from May, but the overall trend remains explosive growth.

Yep, India installed 4 GWh of solar in just the month of April as well.

Solar installation capacity is measured in watts, not watt-hours. So the unit you should he using here is GW, not GWh.

Pushes glasses up nose well actually, we should use GWp, but that's not really a unit and good ol' watts should suffice.

Yeah, you know actually, I know this because I have an EV. I guess I just looked at what the GP posted and posted the same unit.

For batteries, GWh is the correct unit though (storage). Just not for panels/generators/etc.

Really the correct unit is Joules, but try convincing anyone of that.

Watt-hours and joules are the same thing, and you are indeed technically correct, but you'll get funny looks if you ask to buy an 18MJ BESS for your home...

very jealous of how cheap AUS solar prices are. < $1 AUD per watt after rebate

Don't be jealous of our peak power price though: $0.56/kWh

(I have a battery though, so I rarely pay full tote - which is one of the reasons I got a battery)

Not jealous but that’s no worse than much of California (assuming those were USD you quoted, not AUD).

I'd have assumed it was AUD, and even then it's high. I pay 0.28/kWh AUD in Sydney. That'd be 0.2/kWh USD.

That's AUD, so maybe California's a (fair) bit worse then. I always thought the US had pretty darn cheap power.

Looks like California's maximum peak rate is US$0.74/kWh (without including the baseline credit), which is equivalent to AUD$1.04/kWh

Yeahnah, I don't know what I'm complaining about then.

Get solar panels, get batteries!

wow, that's really high. average price for the us is maybe $0.25 kwh adjusted for AUD

We pay like 30 cents in USD per kw.

Average price is $0.19 in the US.

Which is pretty much what Australian average price is. Average Australian domestic tariff is around AUD 0.30/kwh which is USD 0.21/kwh.

None of this touches on standing charges, I don't know how that works in the USA, in Australia for an average household it runs at AUD 1.00/day to AUD 1.50/day (USD 0.70/day to USD 1.00/day). For an average household the standing charge is going to add 15 to 20% to the tariff.

I'm assuming that standing charges are like meter fees here. I've paid as low as $0.25/day and as high as $1.25/day depending on where I lived. There's not much uniformity.

You're confusing the price of electricity with the price of solar panels and/or installation, which is what parent comment intended.

Depends on where you are in the US. I pay 11 cents during peak and 7 cents during off hours.
