Solar panel in shadow

I bought 4 pcs Eufy S340 solo and would like to use it with solar panel.
The left side of my house is facing to the north, so almost no sun over there in my country.
I got almost no options for replacement of the solar else then pointing to the east or north. But there is nothing happening in case of charging. Is there, in this case, too less sunlight? I was hoping for a little bit charging when the panel got a little bit sun… Help me.out please

Does it need full sun?
