How To Make Your Own Windmill - Essential Tips

Buying a ready-made windmill can easily cost anywhere from 12,000 to 30,000 dollars, so it is interesting to consider how to build a windmill for oneself. Actually, doing it yourself is very easy and can be done for under 200 dollars. For this sort of money you will not get a very large windmill, but the potential savings are pretty significant.

So, if you are thinking about making a windmill, what do you need to do first? Before setting out on this project, you should consider a few things first:

• Local average wind speed. Whatever others might tell you, windmills do not operate very well in average winds under 10 mph. The US Department of Energy publishes detailed wind resource maps, which should be checked before making a windmill.
• Building Codes. Check these to see if you can build a windmill. For a small windmill you probably will be OK, but it’s best to make sure.
• Available windmill space. Plan on roughly half an acre for a small windmill.
• Next-door neighbors. It is sensible to include your neighbors in your plans, and prepare to overcome any prejudices about possible noise, TV interference and so on.
• Windmill capacity. You only want a windmill that will generate enough electricity for your needs. The utility company does not have to buy any surplus from you, only offset against your grid consumption.
• Storage. If you intend to live off-grid you will need to have batteries for electricity storage. These are available for free if you know the secret source!. Or plan to use your windmill to partially offset your utility bills.

These are some of the reasons why it is often best to seek advice from windmill experts when planning to build your own windmill. You will then be able to select the right plans for your circumstances, and make sure these include full lists of materials needed for the assembly as well as clear step-by-step instructions.

Small windmills have only a few components. Typically these are:

• A propeller (actually 3 propeller blades fixed to a hub)
• A DC motor
• A fantail
• An axle to which these are fitted
• A mounting pole
• An inverter, if AC is required
• Storage batteries

With some electrical wiring and a few fasteners you will have everything needed to build your own windmill. Almost certainly you will have many of these items in your shed but, even if you have to buy them, you will find it possible to get all required items for under 200 dollars. It is quite feasible to assemble and fit a small windmill in a weekend.
