For solar to work on a commercial scale you have to have a tax appetite. Solar qualifies for a 30% federal tax credit on the total cost of the solar project. In addition you are able to depreciate the entire cost 100% in year one (if you can use it! You have to have gains to offset) Additionally you are entitled to State incentives.(most States have some kind of SREC, or cash grant)

Solar + Bitcoin Mining isn’t enough you need to have another entity that is cash flowing and has a high taxable income.
