There were some discussion among people who want to invest in solar farms. A major hurdle is the interconnection into the grid. There're lots of regulation and large fee to transmit electricity through the gird. From the people who have done it, they just chose not to connect to the grid but sell the electricity directly to the local users, like a local plant. It's quite lucrative with all the tax credits and the sales of green credits while the electricity income was minuscule in comparison. The limitation is they have to be near some major electric users and totally relying on the few users. With bitcoin mining, it's possible to run a solar farm to mine the coins while disconnected from the grid. I'd imagine it's quite competitive without all the interconnected fees.
