Checking, I find the trick was to compare with retail (end-user) price, not the production price of other generators. Not entirely honest, as this comparison is applicable only for off-grid users who have some application that would use all the generated electricity, and the PV price they indicate seems to be the upper bound formed by the feed-in rate rather than the (possibly much lower) production price per kWh.

At any rate, prices are going down.
