The original question I was asking was about residential solar. If you look at the tables in that wikipedia article, you'll see that residential solar costs are much higher than utility scale.

The other point I would make is that IRENA is an activist organization, so it's hard to trust their conclusions without knowing more about how they drew them. There are many ways to do these comparisons and the deck can easily be stacked in favor of renewables for political/ideological reasons.
