yep, being 'still' for a long while will go much better with Solar versus trying to be 'mobile'
I agree with the 'tilt' concern, as well, as everyone may try to get the 'best' panels, and the 'best' batteries, and the 'best' controller, and yet if you simply flat mount your panels to your roof, you'll miss out on much of the sun's power - any cost to tilting is relatively cheap compared to the long-term lost of power by not even trying, if you're really into getting 'all' you can from your system.
