Its been cloudy here all day and they were still generating a kilowatt per hour at around 11am.
Also, we have tariffs here where electricity in the day is more expensive but its dirt cheap at night. So when the battery needs it, I top it up overnight from the grid. 10kwh costs me £0.80p (1€) instead of £3.50 (5€). Do you have anything like that?
Are you sure about them not working?

That far north the winter nights are long and the sun less intense. Still, they’ll make some power, even if cloudy.
