Assuming that you still want oceans to work, about 2/3rds of that is not available, which get us to 500x. You also want land-based plants to work, which gets us to <250x and much of the remainder is unsuitable, so let's call it <100x.
"make equipment" through end-use solar is <20%, so we're down to <20x.
