Solar benefits from storage yes but it's not at all worthless even without it.

If your solar panels generate 10 TWh per year, you have 10 TWh unused hydro, gas, even oil and coal that is stored instead of spent. You have saved the planet from megatons of CO2 emissions even if you have no new green storage.

Solar is already adding the equivalent of several nuclear power plants worth of new electricity every few months. Getting another month's worth of electricity delivered 10 years from now is not much of a bridge.

I think solar and storage just needs every other worse idea to stay out of the way and things will be fine.
