I don't think this is an apt analogy. Electricity is pulled, not pushed. (Well, I realize it is actually a bit more complicated than that, but for the purposes of this conversation, I think the generalization is sufficient.)

If there is no grid-side demand for the energy from my solar panels, then they're not going to be force-feeding it to a grid that doesn't want it.

When you plug a light bulb that's rated to draw 20 watts into a power source capable of delivering 1000 watts, it doesn't blow up your light bulb, because the light bulb only takes what it needs from the source.

It is more complicated on grid level. Some inverters might be smart enough, but some are not. Thus there is both push and pull going on. And this can affect voltage and frequency.
