What's net zero is the line voltage. The issue is partly spinning
mass, but more important is gross gigawatts available on bad
afternoons.

Another time bomb is that (cheap) solar panels and inverters and
batteries don't last as long as is assumed in payback calculations. In
10 or 15 years there will be an enormous disposal problem. And lots of
leaky roofs.
