They are complementary. You tend to have more wind when there's no sun, like during storms and some places are very windy at night. The problem with wind is dealing with the huge uptick in energy coming down the pipeline during a major wind event. Last I checked, this was still not a solved problem but I haven't been keeping current like I used to. So in practice they shut down some windmills during major wind events to protect the system. The other issue both wind and solar have is storage. Though we've seen substantial gains in battery storage in recent years, so there is good news but I don't know if we are really "there" yet.
