You identify yourself as being in NV, but didn't mention whether your new home is also being built in NV.
If we are talking about the Pacific Northwest, where rain and clouds are frequent, I would say the biggest battery bank you could fit, there's no telling how many days you'd need to live off that before the panels could recharge it.
In a desert environment, with sun nearly every day, that becomes much less important.
Also, while battery weight can be significant in a rig that does a lot of driving, if you're just going to park it at your building site, weight becomes much less important.
Finally, if you're building your home yourself, and need to power saws and drills and a compressor to run an air nailer, then obviously you need the biggest bank you can find. And maybe a generator.
