Even on cloudy days you can generate power. Unless it is very thick clouds I generate enough for my base loads even in complete overcast skies because I have an "excess" of PV panels.

does it? Panels are not the most expensive part of the system any more. Overcapacity of panels isn't the bottleneck any more. Battery capacity or roof space might be instead.
