Downsize the main breaker? I would if I could, but the customer only has
100 Amps now, and the solar is fed with two breakers, a 30A and a 40A. So to
be under 120Amps, I would have to size the main to 50 Amps, which may be
problematic.
I can also do the line side tap, but had heard that a load analysis may be
accepted instead. The loads of the house will never use more than 100 Amps. I
am wondering if any codes or white papers detail that option.

Just
downsize the main breaker. For example,
a 200 amp panel w/ a 200 amp main breaker could be reduced to a 150 amp main
breaker to allow for more solar to be connected. You need to calculate for the
120% rule.
