Do you understand how many volts the PV array can still provide on a

This is the kind of data you need

That's AVERAGE insolation without allowance for trees,
dirty panels, aging components, system inefficiencies, etc.
I expect that, with expensive panels and very efficient
converters, you might get 10% of that into useful AC power.

Depending on how far below average before the power cuts off
you're willing to go, you may want several days of storage
capacity and twice the number of solar panels.
If you're using batteries for storage, double the number
so you don't overstress them.

In summer, many of us would have excess capacity out the...
You happen to be in a sweet spot for solar.

If you are not willing to do that, you need the grid.
And you need me to pay for your abuse of the grid.
