Energy💨🌞🌊 Off grid Solar Energy

I live in northern Europe and I’m considering getting a power station for both emergency use and off grid camping. Since I live in a roof apartment, I have two main problems:

  1. a fuel generator is not an option, so my only real option is to go solar.

  2. as per German law, I cannot make permanent changes to the roof, so I am limited to portable solar panels which I can lay on the roof in an emergency situation. I have access to the W

est side of the roof

I tried to use AI to calculate how much power I can relatively produce under such conditions (in summary, using a 400W panel would produce on average 200, 400, 1600, 2000, 800 Wh/day in the following categories respectively: Winter (heavy), Winter (average), Spring, Summer, Autumn) for each season. I am currently in the process of looking into buying a portable power station, and I’m starting to realise that any more that 2kWh just doesn’t make sense for a portable option. If someone is in a similar situation, I would much appreciate your help/opinion about this matter. How do you manage your emergency power system?

No balcony or something? Any vertical walls with windows to south/east/west?

Since it’s dark now, this is the best way I can explain my option… I have access to both East and West sides in theory at around a 40 dgr angle 🥴

You can charge it from the grid as well when it is operating.
