Ok, 110 THash/s would be 3250 watts. 3 x 3250W is 9.75 kW. So simplifying you need around 10kwh / hour. Assuming you’ll need 10-14 hour battery power if you go solar. So you need 100-140kwh in battery storage. This site gives some information to consider when choosing your storage solution:
But you’ll need to generate enough solar for 10kwh mining plus 10-14 * 10kwh in storage for dark times, so you would need to generate more energy during light times:
Energy needs:
24 hours * 10kW = 240kwh
10-hour light availability example:
240kwh / 10h = 24kW average panel yield during sunlight
14-hour light availability example:
240kwh / 14h = 17.14 kW average panel yield during sunlight
Solar price per watt: $1.50 - $2.50
10hour daylight: $36,000- $60,000
14hour daylight: $25,700 - $42,850
Big upfronts on solar, big upfronts on battery storage. I would go with a hydro system if you happen to be blessed with moving water on property.
