Andrew Dillon. However, he acknowledges that excess solar power has yet to cause any blackouts, or damage electricity infrastructure.

The director of the Victorian Energy Policy Center, Bruce Mountain, rejected the argument that rooftop solar could be a problem for the grid.
"I don't buy that at all," he said.

It's just a gripe about nothing. AEMEO sells excess power by auction. By the time they realise they have excess power it's gone.

They will do anything to blame alt; power than shut down a coal plant, or at least one generator.

The greatest item a household can have is solar. Industrial rooftops are filling up more and more.

It's only a whinge from those that are against everything.

Foxy, the problem is not to do with maintenance etc with rooftop panels.
The problem is sudden reductions or increases in output due to cloud
banks passing by. They can be unpredictable.
A modification to home panel systems is possible by the installation of
controllers in the switchboard of each house.
This was predicted at least ten years ago.
The immediate solution is to dump a group of suburbs.
The suggestion that seems to be favorite is to install a controller in
every switch board to enable remote disconnect of panels.

Bazz,

That's right. Maintenance is necessary, but that's a user pays problem.

Bazz That is possible now with smart meters. Who do you pick on first. That is why this does not happen and that is ten years old to.

Every one that puts power into the grid is a power generator and has to be treated as such without favor.

The power regulators are on the job 24/7 its the clumsy outdated coal fired boilers that are the problem. More gas turbines that resemble jet engines that can ramp up or down at a minutes notice or is that too simple.

It is nothing to do with coal fired stations.
To control the voltage etc you must have a feedback loop.
At present when the sun is out there is no feedback.
That means when the voltage or power available is too high that high
level cannot be fed back as a signal to turn the solar panels down.
All they can do is remove whole suburbs or towns.

That simplistically is what it is all about.

Fluctuations in supply are no harder to deal with than the fluctuations in demand that we've always had. Now with big batteries on the grid, it really should be a non issue.

>At present when the sun is out there is no feedback.
False!

>That means when the voltage or power available is too high that high

The inverters do already respond to the voltage getting too high.

The real problem is the perception that the solution is to reduce the output from the solar panels rather than use the excess power to charge batteries.

>solar and wind have certainly raised electricity prices by massive amounts.
What makes you so certain they deserve the blame rather than rising wholesale gas prices?

>They are both environmental disasters.
Far less so than fossil fuels. Stop letting the neocons scam you!

>Surely we will get a Government with enough courage to rip up Paris one day.
Maybe that's why the Libs were so strongly against electric vehicles :-)
