For those who live in Arizona, do you have recommendations on getting Miners to output in AC? I don't know too many people who are mining down here because of the cost of electricity and how it is 120 degrees over the summer. Curious on thoughts surrounding this!
You could get a 100W solar panel, mount a Bitaxe (or two) on the underside. Add a battery with charge controller so it won't cut off when a cloud passes over. Throw it on the roof of your house (unless you need a permit) or build a stand to keep it off the ground. Wipe the dust off when the output drops too low. Could probably build this setup for less than $300. Option to add more batteries/panels to get it running 24/7
Assume you average 30W of generation (assuming 80% efficiency and 12 hours of no generation at night), then you'd rack up 21.6kWh of generation over 30days. Assuming you would have paid $0.16/kWh for grid power, that's a savings of ~$3.50/mo
However, the bitcoin network won't pay you $0.16/kwh (especially with a bitaxe). You'll be lucky to get $0.05/kwh
So a $300 setup would "pay for itself" in about 7-21 years (depending if you count "savings" or "income" as your ROI).
However, you'd learn a lot about electricity and some people pay $50k to a university to go do that, so it could be a massive opportunity depending on your goals!

Sincerely would like to scale this for my own setup , it’s not that you don’t have to pay the electricity company, that’s the bonus - it’s to be so sovereign that no one can turn your hash off, no one can tell you no.
Stay sovereign

Redundancy in all supply chains! This includes energy. Used car batteries are pretty cheap and can be wired in series to get 120/240v with an DC to AC inverter. Even if you keep them charged them with grid power, a little investment in redundancy can be cheap insurance.

Can you run it only at night? Is it significantly cooler at night in the desert?
