Nice, I started with 5 panels (450W each) and a simple design of interchangeable long and short rear legs to adjust the angle of each panel. Base of leg sits in a bracket on a steel frame, and pivots on an M8 bolt. Top of the leg attaches to some angled 'meccano' steel I affixed to the rear of the panels. It worked great, but I slightly over optimized by sharing legs, which made the twice a year switchover a bit tricky, since I could only manage to lift a single panel at a time.

Last year the 550W panels here dropped to 90eur, and so I just added some more panels to remove the need for the switchover. I saw last week 600W panels going for 80eur but no space left, but tempting. Good luck! It's a nice feeling to have energy independence.
