No.

Cooling is probably the easiest problem to solve, easier than power. And in both cases, the problem is solved by mass to orbit. All you need for cooling is a big f-ing radiator. Solar panels are chips, and not trivial to manufacture. But a radiator is just a hunk of metal with some pipes.

That's why the cost of mass to orbit is the most important thing. You can solve almost any space problem by just throwing more mass at it.
