WIND POWER: Electric Windmill Instructions - The Ones That Work

By Brandon Mchale

Saving Time and Costs With The Right Windmill Instructions

Can a homemade system produce as much electricity as an already assembled system? It most definitely can, and at a mere fraction of the cost. There are countless ways to make a small residential windmill more efficient, but it all starts with a good set of instructions. Here's what to look for.

  • Do you have enough wind?
  • What is the point of building a residential windmill for electricity, if you don't have enough wind? Even in low wind areas you can still harness enough wind to power a 6 volt battery bank. Why try to charge a 12 volt bank if your can't achieve the cut in speed required? There are many ways to harness wind power, you first need to determine your electrical demands and what you're working with. The best placement away from obstacles is always your best bet.

  • Are you going to use a battery bank, inverter or both?
  • If you're planning on spinning your electrical meter backwards or supplying off grid energy, your going to want an inverter. Inverters can be built but they do take additional skill and a fundamental knowledge of electricity. Obviously inverters are an additional cost and should be budgeted. There is no sense in having an optimal wind generator backed by an inefficient inverter. The system should be balanced as a whole, considering all components and how they relate to one another. This is also true with battery banks, whether they are: 6V, 12V, 24V or 49V. It all depends on how you series them and what your electrical demands are, compared to your available wind speeds.

  • A word about cut in speed and torque
  • Longer blades don't mean faster RPMs. Longer blades simply mean more torque per RPM. Another factor to consider is that longer blades have more gyroscopic force and make more noise. This is because the tips are moving much faster. A benefit of a wider blade base is the benefit to produce more torque which you can gear up to achieve a higher RPM for more powerful generators. The longer blades do create more torque but often require a higher start up speed. This is where you should consider one design verse two smaller designs and weigh the benefits

You Can Achieve a Much Higher Return on Investment If You Build a System Yourself

With a good set of instructions you'll be able to weigh out the pros and cons of your specific needs and have enough fundamental knowledge to supplement your electrical demand. There is something indescribably rewarding about generating your own electricity and being electrically independent. You're guaranteed a grin every time the wind blows... and that is priceless.
