as of about 2018, solar is cheaper than coal. natural gas is only cheaper because it's a byproduct of oil production. solar is still dropping in price due to technology improvements, and will beat natural gas within the next year or two.

Coal mines have been shuttering - there's a feedback loop here, low demand will reduce the supply, low supply increases the cost, high cost reduces the demand.

Is solar cheaper than coal when excluding subsidies and including storage?

[jes5199]

yes, excluding subsidies. Excluding storage - not yet, or at least, not everywhere. But the cost of storage is falling rapidly, too.
