Generation in this instance means power generation to meet consumption demand. Typically withdrawals from storage are counted as a source of supply to meet that demand regardless of the original source of the power in storage.
So either the solar, wind, etc. datapoints are not being stored or they are double counting. It seems very unlikely all these solar, wind, etc. generators are not storing energy.
It depends on what you're thinking of. No, the solar panels on my roof have no battery on the property. The wind turbines will have inertia, but no other store. I doubt the majority of the solar panel farms have batteries.
