We rebuilt our house in the SF Bay Area in 2022 and went fully electric, no gas line anymore. It was really sad that I couldn't resuse any of my previous 12 kwh solar panels that were fully functioning and had another 10-15 years on them as they wouldn't match the new regulations.
I tried to get them installed on a separate area in my own backyard for off-the-grid charger just for my car, but you are not allowed to have a big off-the-grid system unconnected to PG&E. No electrician was willing to help with risk of losing license. The author was lucky that his dad could help with electrical.
Due to similar issues, I couldn't find anyone to take them for free as well. Demo dad was a truly sad day to watch these perfectly functioning solar panels being destroyed by a crane.
