Solar for barns! Don't know where to start

I've been thinking about installing more solar power in our barn. We already have cameras, and our electric fence run by solar (all in one packs for those), and LOVE them both. I want to think about installing solar panels on the barn roof to power our basic needs instead of running extension cords. We run a 120v hyper tough 5 blade fan during the summer, and a 780w milk machine 2x a day (maybe 1.5hr total?) from Feb/March to September/November. Additionally, I'd like to be able to plug my clippers or blow dryer (to dry off kids born... not doing my hair lol) when needed. I have NO idea where to start with all of that
