1. Can you install the wind turbines generators at your home?
Before you start your project you need to know what your town will let you do. Go to your town hall and talk to the zoning office. This class of wind turbine is new. Most towns have no criteria for this. You may be pioneering for them. I know I did when I did mine.
Before you do anything you need to read this page for planning your job.
5. Plan your Electrical.
This is low voltage so an electrician isn't really needed. 12, 24, and 48 volts is not likely to hurt you, but you could start an electrical fire if you don't plan and protect properly. You need to be pretty good with your hands or get someone who knows proper electrics. You will still need electrical permits and should adhere to the NEC Codes. ( National Electric Codes) If you are planning on towers in your yard, you need to get your power to your utility area. Plan on running an electrical grade PVC pipe underground to your utility area. Refer to a wire distributor for wire size which will dictate pipe size. There's lots of considerations you need to make as you plan your utility area and wiring. Be sure to have ventilation for your batteries. A lot of batteries are best not in your house and located in a separate structure. You need to make sure you are well protected from short circuits with fuses and breakers everywhere. Read the codes to understand more. Welding cable is the best bang for your buck.
2. Study your wind
There is no sense spending loads of money on a system of small farm if you live in a low wind zone. You won't be happy. Any wind turbine requires wind speed to perform. Look at the chart below and see where you are. Grab a beer and a radio and sit in your yard to watch the trees. You may have to sit out there several days to get the whole picture. If the branches are not bending much, you may want to start small with one turbine for low wind. See how it goes. Your elevation has lots to do with that too. It would be great if you bought yourself a small weather station. Then you can watch the game and your meter.
Check the wind chart here for your wind zone.
3. Look at your terrain and environment.
Trees, hills and buildings can be a problem. You will need to get above them of 500 feet or more away from them. Your towers could be 60 or 70 feet in the air. Don't let that scare you! The higher the better. Plan your Turbines for the future growth of the trees.
4. Plan your mounting.
There are 3 different ways of mounting your wind turbines. Keep in mind, what ever you do, make sure your mounting will withstand 100+ mile per hour winds.
B. Wall Mount. Wall mounting will require xome fabrication of brackets. You can't use TV mounts. They need to be made of heavy high grade steel welded and bolted. The wall bracket bases need to span 4 feet and fasten to the beams in the walls. Don't be "cheap"! You'll be glad I said that. My towers are wall mounted nd held up to 110 MPH hurricane winds.
C. Peak Mount.
Peak Mounts are probably the simplest for you to install. You can run them in a row across the top of your roof. They span the ridge on your roof and lag bolt into the roof beams. We're working on a line of peak mounts for resale. There are some wind advantages with these.
6. What are you going to do with the power?
There are 3 ways to use this power. You need to be smart on what you do because the inverters are a major investment.
A, Raw voltage. You can use the low voltage for many things. Water and air heaters are available in low voltage. Low Voltage lighting is readily available.
B. Direct inverter. This is an inverter you would plug into directly. Typically you should have a bank of batteries in this application. This will allow you to use your inverters 24/7. If you have lots of wind in your area, and you are supplimenting solar, you don't need a big batter bank. We suggest you talk to your battery distributor to plan your reserve. Use the charts on our Watt chart page to calculate the size of the inverters you need. We suggest keeping spares and using more than one for redundancy.
C. Grid Tie Inverters. Grid Tie is is simply that. It ties into your house wiring and back feeds into the electric grid. This is used as a suppliment to your electric and bill reducing. Wind turbines will need a small battery bank to act as a voltage regulator. Your wind turbines will feed those inverters 24/7. You also need a controller to prevent over charging in extreme situations. The good news is you get to use what you make first. Bad news is it can't be used as emergency power.
Here is an example of someone's wall mount. He needed to clear somes eves in this design. They're still in service.
Wind Turbine Generators need speed like any alternator. Even the ones in your cars need speed to charge properly. The same applies in wind power.

7. Wiring and wire size. This is very important! I am sure you have used a funnel at one time or another. Think of electricity the same way. You know it is faster to just pour than to use a funnel. It's the same principle. The wire has to be sized to let the watts flow freely. We suggest welding cable because of it's durability, flexibility and easy to work with. A minimum of #10 should be used from a 3 wire PMA to the rectifier (24 & 48 Volt applications). #8 is even better (12 Volt applications) #4 should be used from the rectifier to your utility area. Always oversize for long runs over 100 linier feet
