However the amount of storage (battery or otherwise) for a network of renewable electricity producers depends on the full diversity of the complete network.

Which is to say, for example, that a grid supplied by solar and wind will need proportionally less storage per megawatt as the geographical size of the grid increases. A larger grid "averages out" the intermittent sources better as it gets bigger.

Not for solar. There are no grids nearly large enough to have half in the day time and half in the night time on average.

The type of renewable generator, ie solar, wind, hydroelectric, geothermal and tidal, or a combination thereof is another dimension of grid diversity.
