I am a solar expert to some extent. A Solar that can carry a deep freezer and TV, electric iron can not carry the Mining machine? Let me give a break down of the solar I am using which is not up to the #300k that I earlier mentioned. Solar Panel 150W #36,500 x2, Controller #10,000 x1, Battery 200A, #120k, x1, Inverter 1KVA #45,000, Cable (2yards) #18,000 and Labor #15,000 and the sum total is #244,500 now what you just have to do is to add one extra battery. Backpack Bag Bitcoin Mining Machine is also there to use which can be put at your back move it along. Therefore the 1 million you mentioned is for a very big solar generating plant.
TV does not that consume electricity. Freezer and Iron consume electricity, also air conditioner and pumping machine.
1 horsepower (HP), 920W in average
Iron, 1100W in average
Modern freezer, 310W in average. You can tell us yours because it may be below or above 310W.
On a generator that has 2100W running capacity. Use it for only bulbs and see the hours it would last. Use it with only freezer too. Use it with only AC too and see how it would consume the fuel very fast. Or use it only with iron on for hours and see how it will consume the fuel very fast.
Okay. Let us talk about solar. It uses use use battery with it. The more the electricity consumed the more you need more solar panel and more batteries.
A solar of 300000 naira may not be able to power AC.
What wattage is your Solar generator? And when did you buy and install the solar generator for us to compare inflation rate? With it, we would be able to easily know if it can power AC, but I doubt that solar generator of 300000 naira would be able to power 1hp AC successfully.
Iron wattage is higher than AC. Average of 1100W for iron.
Let us now discussed about miners.You can no more use CPU, neither can you use GPU to mine bitcoin again because of the mining difficulty that has significantly increased because of increase in mining hash rate. Bitcoin mining requires ASICs. Let us talk about 2 Antminers that miners can use profitably these time, provided if electricity supply is cheap.
Bitmain Antminer S19 Pro 110TH - Bitcoin Miner, 3250W
Bitmain Antminer S19 XP 140Th - Bitcoin Miner, 3010W
Three times more power required than iron, almost 4 times or more than 3 times more than 1hp AC.
For more profit, a miner may need more than 1 modern ASIC and just 1 ASIC consumes electricity far more than the appliances that we use at home to generate high hash rate to make mining to be profitable using cheap electricity.
You need more solar panel. You need more batteries. There are days sun is not going to come out at all during raining days, although Norther Nigeria is hotter and better. During hot days, you may need coolers or cooling machines that will also consume electricity. You need more money for electricity if you want to mine with solar. Maybe profitable, but you need to make appropriate calculation for not to run at loss.
Do you know that people are mining bitcoin in their rooms, or palours? What do you think they are using, is it electricity plant? This are the statement people made that is making others to be afraid to go into mining business, mining is not expenses as you thought.
About using plant, I have discussed about it while commenting about using solar just now up on this post, no need for me to repeat it again.
You can not mine bitcoin in your room or living room, ASICs make so much noise that humans around a miner can not bear with. You can use a separate room with sound proof materials and also use noice reducer or so on your miner.
