Why do you think that cheap electricity for bitcoin mining, maybe your intention is easy in payment with bitcoin, not cheap for mining
If use mining it needs to more power so it will use to care. Solar panel is useful to power save and electricity bill save. You will use power to mining process. Mining is counite the network process.
For some of you guys who think solar will help out in getting cheap electricity, have you considered the cost of setting up a solar that would effectively get your miners running 247, which I doubt as well as the cost of maintenance once in a while of the solar panels ?
I guess not! These things do not come cheap and from the last time I checked, they are so expensive that getting back your ROI may take longer than you can even ever imagine. It is best you get it cheap in your country or just find something else to do than mining.
