To put that in perspective: Current global oil use, 75e6 barrels per day, at current price of $75/barrel = 2 trillion US dollars per year.
It's the same cost as 25 years of oil production, at current prices. Even if you think oil price won't go up and solar panel price won't come down, that doesn't seem economically crazy. 25 years is probably about the lifetime of the solar installations.
Infrastructure is a big cost, but the only difference is that the infrastructure cost for oil has already been sunk. It's a one-time changeover cost and eventually there will be no oil.
