If you are planning to get free power or cheap i think building up a solar is the best alternative to have a power where you can mine bitcoin using s9

Solar power for mining isn't always a good idea, it can takes several years to ROI and even more if you live in an area with cheap power. It's really expensive to install.just like this image
Still, OGNasty runs a solar power mining project called NastyMining, you can check it out on the thread.
It probably is easier to move your miners to Iceland. That's not the sort of thing you're going to get much help doing though.
it can be pretty cheap if you put in the effort and know a bit about electronics im building my own solar system (£150 so far got 3x 220A batteries and 3 broken but still working 255w solar panels putting out about 400-500w during the day. might never make a profit but its a hell of alot of fun at the same time
