excellent concept and implementation.

It's inspired me to build something similar but smaller.

I'm planning a roof already tilted for equinox sun at my latitude. Tilt adjustment for summer/winter sun will be optional and if opted for will be a lesser engineering task than starting with a flat roof.

Really awesome setup!

I'm counting 9 solar panels and an 8 battery pack.

How long does it take to charge up the 8 battery pack on a day of full sun?

How long can you run that electric saw mill on the 8 battery pack?

I'm wondering how many of those 8 battery packs one would need for sustained electric saw milling over the course of a week.  I really like those lucas saw mills and they have an electric option that can cut up to 20 inch beams.

Thank you!

Jimbo. I agree that is awesome. Much fancier than what I built. Mine however does what I need it to do presently, was cost effective, and lighter. It's a cargo trailer with 4 panels on the roof and 3 on the side that tilt up. I have construction tools, electric motorcycle, lights, chargers, and electric cookers to run. 6 AGM batteries store energy. I've towed it all over the country working on stuff and camping. It's heavy, single axle, and I wouldn't want it a ounce heavier for my gasoline engine camper van.  Im lugging around materials too so plan to add another axle while also beefing up the frame a little. A 2000 watt Generator is needed sometimes to back it up but not often depending on what I'm using it for.
Running a mill occurred to me too. That would be great. Not with this energy system unless it's a miniature mill. Im considering investing in electric chainsaws and carving tools. Have one saw already.
My dream is to someday park close enough to a stream and use a small portable hydro generator also. Naturally this would vastly reduce generator run time. Batteries can recharge overnight. Again, depending on energy usage.
  I'm trying out a used 3000 watt marine quality inverter I bought from good old craigslist. It has a built in charger. I've noticed that tools seem to run very well on this pure sinewave power. The inverter will start my air compressor that my generator struggles with. Using the air nail gun to build a shed in a day was fun. I needed to start the generator eventually but was happy with the system. Ideally the panels would tilt better. However I've built several tilting arrays that don't get tilted on schedule. It needs to be easy and convenient.
How much power does that electric sawmill require? I'm not sure the 8000 watt inverter shown here will run it? Inverters can be stacked.

Hm, I don't have an answer for you Jeremy, but does it say in any of the videos here?
