Comparatively almost none but yes some. Once every 2 years I think I've read.

I have a diesel challenger. It's a big heavy fuel thirsty 4WD. I barely use it. Probably drive it 5k a year. If I need to go any distance I take the wife's Kia at literally half the fuel. I'd sell it tomorrow if I didn't need it to beach launch my boat.

That's quite a gas guzzling collection.

No boat ramps in your area?

I'll pretend you're asking these questions in good faith.

Yes there are boat ramps. Yes I use them. Yes there are some areas in the ocean that are easier to reach if you drive there and beach launch.

I also use my 4WD to go camping.
 
The interesting this is how fast tech is changing. The next breakthrough in battery tech is nearing market now. Solid State Batteries. They will be a massive boost to EVs as well as a raft of other tech powered by batteries. Longer lasting, more and quicker charge, less fire risk. It won't be the last improvements to battery tech but its the next big one.

Samsung’s 20-year-life EV battery runs 600 miles on 9-minute charge

Samsung's solid-state battery could be the game-changer EVs need, boasting a 600-mile range, 9-minute charging time, and 20-year lifespan.

Samsung has its first pilot production line operational. It expects mass production to commence in 2027.

Also interesting is the word coming from MG on solid state batteries. They say they will commence shipping cars with solid state batteries before the end of 2025.

Game changing electric car battery breakthrough shows China has won the EV battle: 2025 MG to feature solid state batteries years ahead of Toyota and Nissan - Car News

It’s over, the Chinese car makers have won the electric car race. MG’s parent company SAIC has claimed it will start fitting solid state batteries to its vehicle from next year.

It's a real arms race to get first to market.

Yes, yes, we still need base load power at night and when the sun's not shining but 80% solar for the grid is an unreal result. The facts are that's 80% coal and gas that's not being burnt and pumped into the air.

And that's good.

By the end of the day I'll have generated 50kw because the feed into the grid is limited. (If it were unlimited I could produce 120kw on a good day.) . I use 5kw.

Such a shame house batteries are currently so expensive.

The Tesla CEO shared a post on his platform X about the rapid growth of rooftop solar in Western Australia, which now accounts for a whopping 80.5 per cent of the state’s electricity generation on Monday.

At 1.30pm that day, solar output mainly from rooftop installations generated a total of 2.12 gigawatts across the state, according to data from the Australian Energy Market Operator.

The amount of electricity generated by fossil fuels in WA at that moment in time paled in comparison. Natural gas and coal powered only 8.6 per cent and 8.3 per cent of homes, respectively.

Just clarifying Muz, as I'm looking at upgrading my solar system (it's 14 years old), are you saying that for the day you are feeding 50 kWh into the grid while consuming 5kWh yourself from solar, so your total generation from your panels is 55kWh per day? What size system do you have (how many panels, kW rating per panel)?

If you have panels you probably know all this but somebody else might be interested.

Ours is 10.56 kw. We're grid restricted to 5kw per hour. So 5kW/h every hour of sunshine. At the moment at 8am it's almost full blast. At 5pm it starts to taper off. So 9 hours times 5 = 45 kw back to the grid.

I think the feed in tariff is 7cents, so 35 cents an hour. (Bugger all. The days of 30/kw are long gone which is why I want a battery. You can then sell your electricity back into the grid at peak periods.)

Multiple by 8 or 9hrs and it covers the daily access charge which is $1.50 - $2.00 or thereabouts. (Not 100% sure.)

So if you look at the snippy below so far today we have generated 38.6 kwh. (By the end of the day it'll be close to 50kw.) Notice it never generates more than 5 unless it's needed. See those couple of little bumps. That's the kettle or microwave being switch on.)

If we had a bunch of stuff running during the day at 5kw/h the excess panels would kick in to their maximum. Theoretically 10.56kw multiplied by 8 or 9 hours.

So far I've used 5.2kW but the vast majority of that is free. (95%) When the sun goes tonight we'll buy 3 or 4kws at 35-40 cents a kW or whatever peak draw is.

We got the system this year. It was about $9k. We'll pay it off in around about 3 and a half years.

By the by, even when cloudy, light cloud admittedly we're generating 3kw/hr. I think the bloke said something about UV still hitting the panels.

Thanks for that detailed info, I'll have a closer look at it and analyse it.

Yeah, the panels still generate in cloudy conditions because there is still some sunlight/UV getting through.
