CHEAP DIY 2kw Adjustable Solar Array For My Off Grid Homestead

I'm building a large upgrade to replace my 800watt panels and 12 volt batteries. this wasn't quite enough to keep my fridge powered for more than a day or 2 with clouds. And Now with Jon moving onto the property as well he will need some power too. so we're adding another 1200 watts of solar panels to the system and upgrading the batteries to 24 volt Lifepo4 batteries.
I made sure to make the panels adjustable so that they could get the maximum sunlight in all seasons.
