Howdy Y'all!

I've been a member on here for while now and would like to build a wind turbine/solar panel setup for my house. I live in the DFW area and we usually have either sun or wind, so I figure I'd be covered if I used both.

I get the basic idea of how to build the turbine part of this. My biggest question is what do I do with it from here and how do I calculate how large this setup needs to be?

Any information would be greatly appreciated.

Thank you,

Jesse

Message 4 of 16 , Aug 4, 2012
I can address the wind part: If you live in a good wind resource, you can power a home with a 10 kW turbine. Smaller than that and you can make a dent in your electric bill, in proportion to how big the turbine is. For a grid tie system you need a grid tie inverter. For a battery system you need a charge controller and a non-grid-tied inverter. And then to include solar you may combine inverters or noy I think, some electronic systems for wind turbines have inputs for some solar too.

1557 kWh monthly is 52 kWh daily

52 kWh / 12v = 4333 ah daily

With 11mph avg winds, I might not bother with wind at all. You would need a wind turbine with 40' blades or more and 6 hours per day of solid 11 mph winds.

How much sun do you get. Is everyday pretty clear, or do you get a lot of cloudy weather.

Message 9 of 16 , Aug 5, 2012
I would suggest you take a look at absorbing solar energy with water heating panels and store the heated water in an insulated tank.

Then you can generate electricity from the heat in the water by any of several different means. The amount of energy you need would require a very heat absorbing array and a very large tank, but would eliminate a need for batteries.

The simplest way to extract electricity from the water would be with Peltier cells, but they have a low efficiency, only around 2-3%. A slighter efficiency (around 4-5% would be available with a hot air engine and a generator. But that would be so complicated that in the end it might be less expensive to just go with the larger sized absorbers and tank for the Peltier cells.

Have you looked at LED lighting to reduce your power requirements?

Are you using an electric furnace? If so, there is a relatively simple way to eliminate a need for that power hungry device.

Hi. I'm relatively new to this group and have not posted before.
I've found it very interesting.
In reply to the last post re it being an alternator group, ... can I comment, ... I think the prime mover would be of equal importance for the alternator as is the design of alternator itself. Keep up the good work folks. My chance to try my hand at the provision of non grid power for a home and shed in a country area etc. should not be to far away, I hope!!
So I am learning all I can. Thanks. Ken.
