LiFePO4 batteries within the house are the correct resolution.

In winter the panels make nothing anyway, and in summer the houses will essentially run themselves for somewhere between 4 to 8 months depending on peak power usage and panel array size.

Essentially it removes residential baseload and flattens the duck curve so the peak 1600 to 1900 peak can disappear, with the obvious knock on effect of reducing the LCOE.
