It would be best to use different controllers for each source, solar works best with MPPT and wind needs a dump load. Finding a charger controller that did both well would be unlikely. As to the question on how many panels in series and parallel, you first need to pick your charge controller, then the manufacturer will have a string calculator app on there web site that will give you the optimum string for the particular controller. Or skip strings all together and buy micro inverters. Bands I like are Midnight, Victron, and Outback. But there are lots of high quality charge control manufacturers.
As long as all your controllers are set to a safe cut off limit, you will not have issues. If you buy the solar and wind controller from the same manufactures then sometimes they can be setup to talk with each other maximize charging efficiency. My Victron's talk with each other, but it would not matter in my setup as I have them both setup. With the same charge limits anyways.

Just an acceptably efficient system that will tend itself to some degree and at least allow me to cook after a fashion, charge electronic devices, and allow some limited use of the propulsion motor as needed. Any knowledgeable advice or ideas appreciated, before I start buying stuff.
