I was interested in building a btc mining farm, a solar-powered one. It seems to be the future of mining. Unfortunately I can't find enough information about the price of it, but by the models that I see, it looks expensive.
Well i am sure about that, but if you are serious will building a bitcoins mining solar power make sure you have got the informations about the maintenance of hardware solar panel, maybe on your country it is profitable because on in my friends experience it was not profitable because of cost maintenance of hardware solar panel.
