If you're looking for something turn-keyish, you might be able to get some help with this from one or more of the big players in the renewable energy analysis and forecasting space, including (in no particular order) DNV, Vaisala, Bloomberg, and Ventyx. Beware, their offerings can get pretty expensive and there's often no standard list pricing. Also, I strongly encourage you to always do your own validation of any model data they might give you, so the work you're doing to produce your own models is probably not wasted.
