... in case if you are already lost and scared after looking at all the different installs on that list - many of this don't apply to you. Some are old, some are huge, some are tilted, some are made for specific roof material.
If you decide that you only need 200W or less, then it's simple. No beefy wires, no conduits, no roof junction boxes.
If you decide that you need 350W or more, then the easiest way would be to use 24V panels with MPPT controller - not 12V panels and PWM controller. Then you can still have it without beefy wires, conduits and junction boxes on the roof.
No MPPT-bashing here please, - this will be more than the OP can absorb :)
