I think that the overall cost of producing 1 GW of monocrystalline solar PV (a technique China has apparently mastered) is very comparable to the cost of producing a single year's worth of enriched uranium fuel rods, at that's from comparing the costs of acquiring the raw materials, putting them through the requisite processing stages, and producing the finished product.

It's not even close, with some limited exceptions, like Finland and other Artic Circle zones.
