The sun does not have to be out to generate solar.
This has everything to do with coal.
Bazz says to isolate whole suburbs is the only solution, i do not think that is any sort of solution.
coal supporters blame solar for price surges, the only blame solar generators have is being able to produce energy without CO2.
You need to think about what coal does for the only earth we have.

"The sun does not have to be out to generate solar".

They will work in daylight with the Sun covered, but efficiency is impaired. They do NOT work at night, so saying that the sun doesn't have to be "out" is a little on the wild side.

Most people would know that the sun does not shine at night.
You obviously do not have much to do with solar, but you know everything about coal but do not mention that.

Try putting a fluorescent light on a solar panel at night and see what happens

Of course solar panels have output on a overcast day.
The output from mine at midday is about 30% depending on how heavy the overcast.

"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."

Intermittent renewables are just a front for Big Coal, Oil and Gas to carry on business as usual, which is why they are in gleeful support. Batteries have nothing much to do with grid-scale storage, unless you're down to counting out the minutes. If batteries are so viable why aren't Germany and Japan, doyens of environmentalism, interested in them rather than preparing to burn massive amounts of fossil-fuels for decades to come?

Keep dreaming Aidan. Nuclear is here and its best days are coming.

Luciferase asked why Japan and Germany are content to continue burning
fossil fuels ?
I don't think they are content. However I think they now realise that
their countries are too small to have 100% electricity 100% of the time.
