'Maybe 4 panels?'
You can squeeze a pretty damn powerful system into three IMHO.
Any more than one panel is a pretty serious financial outlay on a system you
probably don't fully understand yet.
I started with one and didn't find it too disappointing.
In fact, having progressed to three I ended up downsizing back to the
original panel.
Mind you, that was back in the days you could order and take delivery in
less than 3 months.
If I had to wait 6 months to a year, I'd probably be tempted to order more
in one go like you.
