This is becoming an issue in Australia, we have high solar uptake but a lot of systems were installed before batteries were readily available earlier on or without batteries to save outlay. The result is that there is more energy on the grid during the day while nobody is home and the grid highly utilised at night, but there is less people paying utility fees & usage so the grid will soon become underfunded for repairs and expanding infrastructure.
Its not a problem yet but there will be policy and taxing changes in the near future to account for this (similar to fuel exercise tax being shifted from being tacked onto the fuel prices to instead be some tax or licence fee as we shift to electric/green tech vehicles)
