> All that money we’re coughing up for rooftop solar and batteries at home would be better spent investing in grid scale electricity generation, of any technology.

In my city we literally can't buy any more grid scale solar. We rely on the county for transmission, we're buying all we can, and we're maxed. So you either get solar installed or you're paying some of the highest rates for electricity in the country.

I'm installing the max balcony solar the law allows the day it's legal. It's the biggest no-brainer every, it'll pay itself off in ~2 years in my case because it's knocking out the most expensive part of my power bill.
