Welcome to EM! In LA, the great thing about replacing your AC load with PV is that you are also helping others by "giving back" your juice while the grid is suffering peak-load. The fewer ACs that are running, the less chance of a power outage.

I have since lost it, but there was a website that was packaging "Conventional AC + PV" power systems. It was taking advantage of the California PV incentive programs to sell you AC systems with PV sized for the AC. This sounds like your strategy, i.e. take out the Big-Kahuna AC load.

Question: I have a window mounted 1.5 ton AC unit (18000 BTUs) for our 900+ sqft home :

In your opinion, how many KW of PV would I need to offset that?
