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.)

Yeah, i would definitely look at LIFEPO4. People just have the name recognition of "lithium" so they don't really understand the differences between that and lithium ion, and so from what I saw last time I checked, the price was not really different, even though LIFEPO4 lasts longer and is safer.
