I'll admit that I'm currently completely ignorant about crypto mining. But I will be building a house next year, and intend to set up a 10kw solar array on the roof (with enough expansion for another 5kw) with battery storage. Yeah, my roof will be that big. So by my back-of-a-napkin calculation, with the 10kw I will have some yearly excess power, and with 15kw I'd definitely have surplus. Was thinking that setting up a crypto miner would be a no-brainer.
be sure to design for heat management
My plan is a central heat stack with all the equipment racks and refrigeration condensers backed up to it. In the summer I will open a duct and all that heat will rise up and out. In the winter close the duct and the lower end of the stack will be integrated with the furnace cold air return.
