Depends where you live. IIRC California made it more difficult to have solar installed. Where I am there is a cap on the size of installation I can get, and how much I can produce.

Yes the technology is there and it’s great, but regulatory capture is still a huge problem.

If you're building something new, it's a no-brainer, even. You can use panels as the roofing material rather than an additional layer now. There's both fancy products like the Tesla one and more practical options.

Any idea when this happened? I live in a state with cheap electric and a few years ago after doing the calculation it wasn't worth it to invest in solar. I'd love if that's changed in the past 4 years.

Unfortunately that doesn't work for all of us. Solar isn't very viable where I live, since there's not much sunshine.

Combustion engine car makers are hurtling towards their Kodak moment

If EV companies can collectively work on a proper open standards like the digital world, it would come a lot sooner and more people would benefit. It's not just about the price, there needs to be reliable access to charging stations, support, maintenance, easy/affordable access to repair parts, and recycling. But everyone wants to please their own shareholders, so we have things like EV graveyards. So it still remains to be seen how quickly we can phase out ICE cars.

Every EV with their own proprietary systems just adds to the dilemma for people who want to switch.

The 5000 refers to cars with bigger batteries than a 10.000 dollar car. Those might go down to 7 or 8 K, but new cars sold in Europe or the US will not likely go back down to below 15k. The necessary safety and environmental requirements, and minimum expectations on comfort, features and performance will likely keep prices relatively high-ish. Even the Citroën Ami is still 9k, and that's a 2 person city car with low range, barely any features, and loads of cost cutting. Awesome car, though.
