In northern California, solar produces more in comparison to most places. That means that could still have credits left over after cancelling your bill. In that case, PG&E can either write you a check crediting you at their retail rate or you may use the credit for 12 months on future bills.
The new NEM-2 rules require new solar customers with PG&E to switch to time of use billing reducing the returns by about 10%. However, with excellent power generation and solar becoming much cheaper solar is still a great investment.
