I have free electricity thats why I don't bother to include, and I have a single phase 120v, thanks for replying mate.

@Philipma

I have a house with 24kw and its extra land in the back, I plan to use that piece of land for the mining farm.

I am thinking about adding large numbers of solar panels on the roof to mine during the day as well, I shouldn't have cooling issues because my compound is mostly breezy all the time.

Thanks for the replies.

Hey mate... First thing first is your electricity cost... It's only economical if you have access to electricity price of below 0.04$cent/kwh. Otherwise i strongly suggest not to do it!
So let's assume you have that cheap electricity price. Then considering your 24 kw electrical capacity, you very likey be able to run max ASIC OF 6-7.... Although efficiency matters much, but maintenance and its risk control is also very important. Cuz you will end up so much in situations that your machines will fail!... So try to increase the number of your ASICs even with sacrificing a bit their efficiency!
So, for instance, instead of 6 high efficiency machines, i would go for less efficient ones but with number of 12 miners in my farm... That makes it more easier for maintenence and bring higher uptime of your farm, in cases that some may fail!

But the electricity price is still the important factor here ☝️
