If you're in a remote area, why not use a regular greenhouse?
Further, solar power takes the same area as you can use to grow crops anyway.
Though I couldn't get the link you gave to cooperate, I have seen examples of cold weather greenhouse installations before, so I know that it can work.
But, if you have excess power from a large turbine it could work.
PS: Solar has surprisingly high energy density. Try running some numbers for this stuff.
