Yes, it's bad.

So all our PCs are now on our solar backup ac mains. About 8000 Wh. During summer we set it to PV panel priority. Right now it's set to charge from grid if batteries are less than 90% as there is little charging for the next two months and higher likelihood of power cuts.

We have 12 main PV (400W each at clear sky June/July near noon!) and two auxilary ones that can be on the main system or a portable one. They can fit in the car (100W rating at full sunlight).

You get 1/10th to 1/20th of the solar electricty this time of year. You can't easily "over panel" if you are even only as far north as the Mid West of Ireland. Design for late autumn & early spring, or even winter if you have enough space. Decent panels less than €220 each and need not be on a south facing roof, or even a roof. Batteries are the most expensive bit, but good LiFePO4 can now last 10 to 12 years at deep daily cycling.
