The question isn't is it an insurmountable problem. The question is if it is an economically sound way of doing things. And the answer is a resounding no just from thinking about conservation of energy: you will need an area of land at least ten times the size of that covered in snow to melt it from the simple fact that turning heat into power to turn back into heat is in incredibly inefficient process and during winter there is more than 12 hours of night in which solar panels don't work. And 100 trillion dollars worth of batteries isn't a solution either.
