House is facing South, but I'm laying them flat on the floor for economic and aesthetic reasons, with some 3D printed brick-based ballast [1].

Buying supports for PV is actually less economical than buying additional PV panels.

Its my south/west balcony with a 1 square meter panel from some online shop. 400 watts, with an easy to install rail system for my balcony and a plug and inverter for ~400 Euros.
