I have a friend who is living completely off grid. They have more than enough energy through solar panels and batteries for their families daily consumption. I want to understand more about what it would take to mine Bitcoin with the excess energy that they aren't using and whether it would be worth pursuing since the electricity is "free".
Take for example the S21 which runs at around 3.5KW.
One thing I'm not sure about is if the 3.5KW this miner uses is per hour or daily? (I'm assuming it's per hour.)
So in this particular off grid set up, would an S21 be pulling consistently around 3.5KW from the solar panels during the day, while at night the batteries would need around 40-60KW of capacity just to keep this miner running?
I know that these miners use a lot of electricity, but this estimate feels like it's too much for just one.
I'm hoping someone here can clear this up for me if I've made a mistake. Thanks in advance!
