farming on the solar electricity is a great idea! The only issue that blockchain will suffer at night ). You need to add pretty big accums to the system to meet next day working.
There is a standard that people are trained to believe. This is a new trail. Consider this..... The miners generate a ton of heat. During the day, we make energy, then at night when it is much cooler we mine Bitcoin, Litecoin etc. However, at some point in the future the Sun Farm should be large enough to run 24 hours per day but for now, the first step will be mining at night.
