What you want to do is replace your service panel with a 200 amp panel, then replace the main breaker in it with a 125 amp breaker. For my GE panel this was easy to do but I had to order the main breaker kit online.
Then you'll have lots of room for solar.
It would be too easy. They won't allow a 200A panel for the reasons stated above, and they left no room for interpretation.
I'm sorry, that's what I get for replying on my phone and not reading your entire message.
So do they also disallow 125 amp panels that a 200 amp main breaker will fit into?! What if someone puts in a 200 amp breaker, think of the children!
So how did the utility even get involved in that part if the conversation? In my experience the utility and the AHJ are very hands off each others parts. For me my utility insisted I had a 200 amp service even though the gauge of the wire was clearly not what a modern 200 amp service would support. My AHJ was not at all concerned with the size of the utilities wire as long as the meter box and the wire from the meter box were both rated for 200 amps. I ended up not going to 200 amp because it would have required having the utility disconnect power to replace the meter box. Instead we just replaced the wire from the meter to the panel with 125 amp rated and put in the 125 amp breaker. The utility never touched foot inside my house and has no idea what the inside wiring is like.
Ray, your suggestion would still have the same issue but would just move it.
I'd be surprised they would let you do any taps since then a future owner could stop using solar and use the solar panel and use the panel for their grow op.
I've often wondered what lives in a transformer to protect the wiring and this seems to confirm that they leave them unprotected as clearly the answer is a 125 amp fuse on the transformer would avoid this all together.
The funny thing is my 1969 house is it came with a split bus panel. The main breaker was 60 amps but the top of the bus allowed for 4 or 8 half breakers. So you could eaisly add more breakers than the service was rated for. No one cared when I had 30 amp for dryer, 30 amp for old water heater, and new 40 amp for the EVSE and the 60 amp main, all 240 volt.
Do they make 125 amp panels with enough circuits to handle your house? Seems like you might need a sub panel to handle all the circuits.
How big of a system are you thinking? NEC/AHJ might not be happy with such a small main breaker but what about putting a 100 amp main breaker in a 125 amp panel? This would be safe and I doubt your house will ever have above an 80 amp draw. I turned on literally every thing in my entire house and barely got over 50 amp at 240 volt.
