Hey everyone! I'm in a bit of a bind and need some advice from my fellow solar users in California, particularly those with SDG&E. I initially had a NEM 2.0 system with 17 solar panels (about 7 kW), but recently upgraded to a total of 30 panels (approximately 14 kW) during some roof work. Right now, I've only activated the first 17-panel string (around 8.3 kW) to stay compliant with the NEM 2.0 10% increase rule. The new 13-panel string (5.3 kW) is installed but currently disconnected.
I'm aware that if I submit an update now, SDG&E might revoke my NEM 2.0 status and switch me to NEM 3.0, which means lower export value even though I'd have more production. My dilemma is that my current system isn't fully offsetting my winter usage, and I still see bills around $200 some months.
So here are my options:
1. Keep the second string off and stay compliant under NEM 2.0.
2. Submit an interconnection update and turn on the second string, accepting the switch to NEM 3.0.
3. Quietly activate the second string and risk getting caught, knowing I could switch to NEM 3.0 retroactively anyway.
What do you all think? Is it worth sticking with NEM 2.0 despite wasting some capacity? Or should I just turn everything on and enjoy the benefits while it lasts? Looking for insights from those who've faced similar choices. Thanks a bunch!

Have you thought about a fourth option? You could keep the second string disconnected, add some batteries and an off-grid inverter, and use that as an off-grid system. You can move lower priority loads onto it during the day, which lets your main compliant system export as much energy as possible. The best part is that the grid won't even know!
I really like option 4 too! Curious, though, did you mention the size of your inverter?
