Around here, wholesale producers get paid wholesale rates to sell power to the power company (or to consumers). The consumers also pay a fairly large charge for use of the grid to transfer power from producer to consumer. So while a producer might get $0.10/Kw-hr, the consumer will pay double or triple that (or more).
What we have here in California is "net metering", where we get paid exactly what we would have been charge for the same power, assuming we are using some approved source like solar. It makes money for the power transmission companies as solar produces power at peak demand times (at least in our climate) and sure is nicer for us than selling them our excess at the low wholesale rates.
Some countries (Germany, etc) have a lot more incentives that, I assume, make the seller some real bucks. Germany has really raised the worldwide price of panels by soaking up the world supply: they cost more recently than about four years ago. Too bad: we would have installed a lot more in sunny California if they had not installed so many in cloudy Germany.

Unintended consequences!
