What's net zero is the line voltage. The issue is partly spinning

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

Yep.  And given the likely end of the mandates and subsidies,
replacement may prove expensive, making the business case less
attractive.

 Twaddle. Solar panels and wind turbines are the cheapest sources of electricity available - certainly for Australia and Spain.
 

You really need to ease up on the Koolaid, tastes nice, but short
term benefit.
Just how long do you think the battery farms will last under constant
charge / discharge cycling, and how much will it cost to replace them ?
Complete fools errand, but i''m sure the salesman must have been quite
persuasive :-).
