I want solar on my roof but I need a lot more education. It seems I can either throw extra money at an installer who knows what's needed and how to walk the permitting walk (HOA & City & Grid Provider), or figure it out enough to order pieces and contract (or beg) the labor for less.
I do know the difference between Micro-Inverters and Optimizers, and how to build in capability for a future bank of batteries, but OTOH I don't even know what (Panels) "Grade A, Grade B, Grade C" mean. Or what good rails & layout look like.
