Amps is amps.... any way you cut it. Wind generated power goes for just under $4 a rated watt hour and up, solar starts at about $7 a rated watt hour and goes up with mounts. The only question is which system in your situation puts the most amps in a battery for the cheapest cost. The batteries and controlers are the same, and cost extra for both systems , and required if you expect to operate off the grid.
For solar you are only going to get rated watts under very specific conditions without adding a somewhat expensive sun tracking mounts. Maybe full rated power for two hours on a sunny clear day, and somewhat reduced output thru the rest of suns arc on a fixed mount.
For wind you are only going to get rated output if the wind blows above a certain threshold speed depending on the model ect, but the wind can blow in the night.. bruuuhahahahha...

If you are serious about doing this my suggestion is to get about $1500 bucks worth of solar or about 200 watts worth, $1500 worth of wind power or about 400 watts, spend another $1500 on about 400 amp hours of batteries, proper controlers, an energy sink, an interface box for the house and proper instalation and put little total input type amp meters in line to record how many amps each of the two options , wind and solar, generate under your local conditions. You will also learn enough to wisely and inexpensively discover the relative pro's and cons of each option while creating a small totally off the grid system that can still provide a useable amount of power in the meantime. This will allow you to have something until you decide what you need to create a complete off grid system.
Local conditions are so variable, this is about the only way I can think of to really truely know what is the better option. Typically you will find , as an average, wind speeds are slower and less frequent during the summer when solar is more available with longer days, more sunnier days, and higher sun angles , and that winds are stronger and more frequent in the winter when solar suffers from shorter days, more cloudy weather, lower sun angles.
Both combined, with other system possibliities , water power , regular and LP generators, a little power from here, a little power from there type set up, will probably work better in the long run than some monolithic single source system.
When it comes to generators you can multifuel your generators to run off any number of fuel options , biodesiel, alcohol , LP , hydrogen, woodgas, what have you fuelwise, that you can "make at home" as well as gasoline.
What I haven't looked into is steam power... for me, with all the trees here, that is something I really need to check out..... http://www.mikebrownsolutions.com/20hpse.htm. A 20 HP engine will run a 10 Kw generator.. thats only a $1 a watt for all the gear .. steam engine , generator , batteries , controler ...... what I don't know is fuel use and tending requirerments... convience and transparency.. the pro's and cons outside of price.. I suspect some sort of shelter or outbuilding wood storage and generator protection.. noise levels .. but it looks promising price wise... also you can pick up twigs, as they say, for fuel, but you need relatively clean water in quanity.. that might be harder.. or not depending on your location.

Don't forget steam power http://www.mikebrownsolutions.com/20hpse.htm priced under $1 a rated watt , 20HP is about 10 Kw a cord of wood is about 3000 Kw which translates into about 25000 amps @ 120 volts assuming a 50% system overall efficency.
