I am in the beginning process of installing a second solar array to our existing system. First system is under NEM 1, installed in 2011. According to PG&E I have 2 options, move both systems to NEM 2.0 and keep my original grandfather date. This is not ideal, since I only have 10 years left. Second option is to install a Net Generation Output Meter keeping the first system on NEM 1, second system goes to NEM 2 with new grandfather date. I prefer the 2nd option, but have received mixed information from Tesla. I called PG&E, and they were also no help at all, other then sending me to an order form to have a meter installed. I spoke with two different people at Tesla, one said yes, they take care of all that, another said I had to coordinate with PG&E. PG&E would not give me any pricing on installing a meter, and kept referring to it as an EV meter even after I explained what I was doing. Hoping someone here has gone through a similar process and can give me some pointers. Both systems are PV only, no Powerwalls or batteries etc.

Thanks for any input,
Brian

I would just go to NEM2. And since who knows what will happen in the future, I would not assume NEM2, or even NEM1 will stick around to the end of the 20 year dates
