Australia has the highest per capita rooftop solar panel uptake in the world, so EVs becoming less gimmicky

article below about a survey in Sydney and Hunter Valley shows most EV owners have rooftop solar

Pity manufacturers won't send their EVs here because, you know, the government


The problem that we have in this country (and I think this is where additional development of batteries come into play) is that rooftop solar generally only produces significant power between the hours of 8am to 6pm. It may work for some at this time, but for many they are at work, so unless the uptake in batteries alongside solar increases then, those system will export solar power to the grid during the off peak hours and then import electricity back from the grid at peak usage times of early evening and then overnight.

Don't get me wrong, I'm a massive advocate for rooftop solar and I would love all homes and businesses to have rooftop solar eventually, but obviously changes to our grid network will be required, or if they can utilise battery technology to store the power generated then the power can be more controlled back into the grid, as the grid could drain the battery when a home isn't using the energy in off peak hours.

Its the way forward, but at the moment, much of that power still used outside of daylight hours is still produced by coal (particularly in NSW and VIC I think) so charging cars at this time are utilising coal power to charge them.

I would love to see a day when we have a fully integrated 360 degree grid system, whereby controlled release and distribution of solar power is optimised but we aren't anywhere near that level right now unfortunately. In some ways solar power installation is advancing too fast in that installation is outpacing the grid upgrade that is required to create the optimised system of the future.

Is it possible to "overcharge" and kill the battery if you forget to stop the charging process?

How much is a wall connector worth including installation?

Is it safe to charge in the rain?

What I'm getting at is, if I get home after a day trip and need the car in the morning, how long am I going to have to stay awake while the bastard charges?
Pretty sure they'll charge up overnight.
But you'll need a big farkin battery pack attached to your sun shiny solar panels to charge your car up, or use smelly old coal fired lectricity if you don't have the solar battery pack. You could always leave your lectrict car at home during the day n charge the battery while the sun is shining of course n walk to work.

I don’t think so. We use electric forklifts at work and smart chargers are just that, they prevent overcharging.

Did you even read that article?

Here's a quote:

In the meantime, while the unexpected, decades-long overall increases in Antarctic sea ice extent are still being puzzled out, the sea ice extent has taken a dramatic turn from relatively gradual increases to rapid decreases. On a yearly average basis, the peak sea ice extent since 1978 came in 2014. Since then, the decreases have been so great that the yearly averages for 2017 and 2018 are the lowest in the entire 1979–2018 record, essentially wiping out the 35 y of overall ice extent increases in just a few years.

Which agrees with the graph I posted.

Not growing, was growing, but no more.

Melb water storages at almost 90% with heavy rains predicted this weekend. We could be over 90% shortly. Remarkable.

How much is that desal plant down at Wonthaggi still costing...? Talk about overreaction.

How good's Straya?

What an absolute disgrace.

Its "technology investment roadmap" was deemed insufficient to decarbonise the economy, cut fossil fuel use and promote renewables.

"This failure to promote renewables ... is exacerbated by inadequate infrastructure investment despite subsidies for fossil fuel production and promotion of a 'gas-led' economic recovery following COVID-19," the ranking said.

"The country's international standing has been damaged by climate denialism by politicians, refusal to increase ambition and refusal to recommit to international green finance mechanisms."

Lucky we didn't get any of that rain that Flannery predicted would never fill any of our dams. We musta got the proper old fashioned wet rain instead.

I am liking Andrew Forrest's rhetoric recently on climate change. We need more people like him championing the economic benefits of clean energy, not just the environmental side of things.

Another view is he is trying to create a new monopoly by blocking competition from other hydrogen sources. That’s what I’d do as a capitalist.

Are you referring to blue and grey hydrogen alternatives? If he's guilt tripping others into green hydrogen then I'm all for it.

I’d imagine he would lobby government to ban them.

I’d prefer a price on carbon and let markets sort it out.

If green hydrogen wins in that scenario then great.
