Someone ask this
question on Nigerians local board, the reason why miners are not located or negligibly located in Nigeria as a result of poor electricity supply. In Nigeria, electricity supply is poor in many areas and the only option anyone that want to mine can have is to use solar energy.
Assuming you get yourself like one or two Antminer S19 Pro, powering it with solar, will it be profitable after considering the budget and maintenance?
Those miners and solar panels are not manufactured in Nigeria, they are probably manufactured in China which will make them costly as they will be shipped.
if i have the money i will do it, a s19 consume ~ 3200w so if you want to run 2 you may need about 8kw of solar power, and a battery of at least 40kwh to serve as a buffer, and only mine from sunshine to sunset, it does not worth to do for 24hrs you will need 7kw x ~12hrs = a battery bank of at least 100+ KWh to be able to discharge it to a safety level for it life purpose
