What are you wanting to know? I have 24 panels on my house... Installed last August. I'm completely self sufficient and then some... In fact I get a check from the electric company.
Granted, I am in Denver. We have 300 plus days of sunshine. You would want them facing south, don't even attempt it if youre thinking north.
Axis panels are lots of upfront money. They weren't worth it IMO. I've got the tallest home around with a custom mount to face south. My system in total was around 30k.
