Solar actually thrives in the winter. Panels' enemy is heat, and snow is happy to soak that up and quickly melt, sliding itself off.

Even during overcast or rainy days, you'd be surprised how much sun energy still comes through.

Ah yes. There is no sun in winter.

There's no sun under 5 feet of snow. There's also much less sun in overcast. And even less sun at northern latitudes.

Oh, and bonus, wildfire smoke blotting out the sun regularly in the summers now!

Seems sensible to pick a power source that doesn't depend on the sun with that many variables.

I’ve lived in places in the US where the sun didn’t shine for an entire month in a particularly bad season. I have no idea what a month long utility-grade battery looks like but I’m pretty sure it doesn’t exist.

In winter solars produce fraction of the energy that they do in summer. You would need to oversize them 10x or even more. But then, during summer it would be wasted, unless you have a large accumulator.

Yes, that is a thing in parts of the world.

But they were discussing a particular part, no?
