Hey-o!
Not to “bah humbug”, but I’m also currently working on my solar at the moment, and to be honest for the $4500 or so I’ve spent on my solar panel system…
It’s honestly SUPER disappointing.
Solar Power is a great secondary, but as a primary, I would really personally suggest going with shore power, a generator, or even using an isolator off your engine. Apparently, and I’m just learning about this now so I’m not 100% on the quality or capability of it, but there is also a “DC to DC Charging Isolator” that has more to offer than just isolating off your engine.

If I could do this all over again, I would spend the bulk of my money in any one of those areas rather than solar, then once I had a solid primary, I would spend whatever I felt comfortable with on solar.
Like I said, not trying to discourage your use of solar, it’s just that for all the money I’ve spent my electrician that is hooking up my system (A friend who is a professional electrician and owns his own company), he’s telling me that I’m probably not even going to be able to run my fridge 24/7 without draining my batteries. (Although, I did end up going with a fridge that is 120 and not 12v as I should have.)
I really bought into the whole solar power thing watching Youtube videos where they made it seem like they are running purely off solar and keeping their battery charge full. $4500 later, I can tell you the only thing they are full of is
