You need to have enough storage for the evening. Bad PV days can be overcome by adding more panels. I am looking at adding another four to my current 16 for a total of 7.6 kWp.
I did not mean you need 24hrs of battery storage. My point was you need a generator, because if the PV is really bad during the day, those batteries won't be charged enough to carry you through the night.
