Has anyone done any systems like this? Tried searching the forums and didn't see too much about it. I have average wind speeds where I am of at least 20mph, and sunlight a good chunk of the year has direct sunlight.

Where are you?
For the wind, the larger the unit you get the more wind you need to make it generate.
If you have average wind speeds below about 10 you are going to have a hard time getting it to pencil out.
For solar if you have good sun that can work for you. You can do DIY and by the panels for about $1 per watt and then buy the inverter you need.
Total install if you do it yourself should be about $3 per watt and if you hire it out you should be able to do about $5 a wall or a little less.

Hey Bob, I live in Rapid City, SD and I'm looking at having a setup for emergency power/misc landscaping lights to run all night. We've had weeks where we have an avg of 30mph throughout the day. The highest I've seen so far has be 55mph gusting.

Dodge,

Lots of requirement and restrictions. If you put up a tall unit for wind power, you have to have 1.5 X the height as a clear fall zone. Here is some information on solar power systems...

What about just having a smaller unit for emergency power/LED lighting?

For wind to work it needs to be high....normal terrain really cuts down the wind speed....i.e., the closer to the ground you get, the less wind you have.

Solar is more DIY doable...

I'll make it simple.
You will have an outlay of funds that takes many many years to recoup, if ever.

We have a camp of folks who think a ten year period to get your investment returned, and then another ten to double your money is a fine thing.

We have a camp that believes it is silly, trendy, and of no value as an investment.

This forum really isn't a good place to ask about such.

As emergency backup...it just isn't. Both sides agree on that.

Do you have any forum recommendations for wind power?

The good news/bad news is that those wind speeds I talked about earlier are at 10 ft off the ground :/

Very true ! Trees and structure will kill your power output. Even on "the plains" they put windmills up over 20' high !

Unless you are charging batteries for a small shed, for wind you will need a big turbine and a tall tower to have any hope of reasonable power. There are 1000s of turbines here and they work well - with 60' blades on 330 meter tall towers. Little ones like the Whisper series run small green houses and the occasional billboard. Turbines are rated at a steady wind speed that you will seldom see and it doesn't always blow either. There are wind charts you can use to get an idea of how many watts average you can get from wind.
