Solar power station DIY projects? (palaver.p3x.de)

I just found out I can buy a decent 400W solar panel in the local hardware store for around 90€ these days.

Are there people around with experience in off-grid solar? There is quite some supply in cheap MPTT charge controllers on the internet. And I can't afford a 700€ power station. But I would be able to buy a few power tool batteries or one of the lead-acid batteries people put in their caravan. Are there projects building a power station myself? Is this even worth it?

Maybe someone alredy wrote a blog post with recommendations or findings and failures along the way. Or has something similar running at home?

(Thanks to the mods for steering me towards the correct community.)

Its essentially my garage and workbench with tools. My home doesnt have a garage so I made one. I built a modest bench into the nose of the trailer and put the inverter, battery and equipment under it. There is a cell hotspot and raspberry pi that controls the vent fans, exterior lights, etc so its a fully self contained, mobile workshop I can take wherever and I control it all from a website and get solar analytics. I usually park it way out back on my property.
