Solar Flooded Australia Told Its ok to Waste Some.

Amid the growing warmth and increasingly volatile weather of an approaching summer, Australia passed a remarkable milestone this week.

The number of homes and businesses with a solar installation clicked past 4 million — barely 20 years since there was practically none anywhere in the country.

Any leaking electricity should go into community batteries for street lighting.

Integrate solar panels into ceramic rooftiling with air channels between them.

use olar powered ventilation to move out the hot air between the solar panel and the roof tile.

Just desalinate more water.

Batteries are expensive.
And there is such a thing as “too much solar”. (Where “Solar” = irregular, unreliable supply)

I think broadly there isn’t really a great understanding in the community of how AC power and electricity grid actually works and what impact intermittent and irregular supply can have on the stability of the system.

Ideally a balanced load across the whole grid.
Wind storms create supply problems and can affect the grid.
Remember SA feirce wind storm.

I have said it before and will say it again – Decentralised, consumer battery storage with live buy/sell pricing is the way to go.

It is heading that way in places.

Some interesting tid bits off the net.

We cannot store AC in batteries because AC changes their polarity up to 50 (When frequency = 50 Hz) or 60 (When frequency = 60 Hz) times in a second.

AC batteries are not actually batteries, but converters that create AC current out of DC battery supplies.

AC-coupled batteries tend to have an efficiency of 90–94%, while DC-coupled solar batteries are closer to 98%.

As a rule of thumb, AC-coupled batteries are better suited for adding into existing solar systems while DC-coupled are better suited for installing at the same time as the solar panels. However, with enough time, money, and installation expertise, it is possible to configure a DC-coupled battery into an existing solar system.

Some Differences between AC and DC
They are different in an almost unlimited number of ways. Chemistry, which is used in batteries, only makes DC. The downside of DC is that you can’t change the voltage easily. AC, on the other hand, lets you freely change the voltage using a transformer, constrained by the power.29 June 2021

Indeed. “Solar can generate electricity x% cheaper than coal for a fraction of the cost!”
That is all well and good assuming you only want to use electricity when the sun shines. If you want to supply power 24/7, then it’s gunna cost more.

So should I cut down the trees that may otherwise reduce the amount of sun the panels would see?

The average generation of a 1kW panel is about 5kWh per day. You could always shine a floodlight on the panels during the night time to increase reliability.

better yet you should burn coal and gas over the panels and use them to collect the light from the flame, yellow is brighter
