The first a unit of energy. As in total output from an input (building the panel). The second is a unit of power because the silver isn't used up (it's made very very hard to recycle in the NPP, but it's still technically possible after a few decades), the issue is how much is occupied by the equipment. If you can't understand the distinction between power and energy maybe we shouldn't consider your position on power and energy credible.
