I don't understand the obsession with mining using solar power. To me it's the worst
combination because efficient mining requires reliable power 24/7.
I would look at it from a different point of view. How can I best use the solar power in real time?
Can I use it all in real time? How can I schedule my power use to maximize the use of solar and minimize
the use of grid?
Everything you offload from the grid reduces your mining costs.
Anyways, I'm mining on solar 24/7 with no grid power at all, it's all about calculations, assuming your rig needs only 1000 watt power I suggest going for 3000 watts solar panel, why? You will be able to mine when sun is up and also charge your battery backup for when the sun goes down, I'm running this 24/7 and it works
Do some math, get more solar panels and enough battery bank that will last you from when sun is down to the next day when sun will be up, remember, the more the panels the better
