Depends how you do it, if its just a thin reflective foil focusing light on a few collectors then we could probably do it inside a century on just the worlds current production capacity. (baring actually getting all the foil there and engineering collectors and so on, just talking making the foil itself here)

I think that would just make a really big solar oven.
Thats the basis of quite a few solar power plants.
