I did build my own solar system too. In Switzerland.
Took me 1-2 month planning and then 3 month building it alone nearly each day. Sept 2023 til Xmas 2023. Got all the hardware from a PV dealer friend on his purchase price level. Even 24 panels I have put myself alone onto the roof. With two persons it was a bit better.
I've got: 420w x 71 Trina solar panels and two SolarEdge inverters. SE10K Hybrid and a SE17k. Also a 24kWh BYD LFP battery.
All prices without state funding:
Offers from local installers for 56*410W Panels without battery were around 65k CHF.
I've paid now 44k CHF including every kind of cost associated with building it.

Should write a blog post about it :-)
Next project is a solar fence with 6kWp.
