Windmills for Electricity

The world’s best residential windmills for electricity guides reviewed side-by-side.

The following guides all offer full plans, pictures and videos to help you make your own home made wind generator.

The guides we recommend here are not the expensive commercial type. They are the low cost type and involve sourcing new and used parts from local suppliers and hardware stores (full details enclosed).

Windmills For Electricity Basic Instructions

Windmills for electricity can be very economical if you build them yourself.

The whole process is not as hard as you might think and with a lot of the electronic parts semi-assembled these days, a lot of the technical aspects are also a lot easier.

Windmills for electricity can be very useful if you live in a remote area off the main grid. They can also be handy for camping and / or long road trips.

This article is going to briefly go over what you’ll need to build your own electricity producing windmill and also how to put it together.

This article itself is by no means a complete guide, it is written merely to illustrate to you the process and what is involved. The first thing you’ll need to find is a small generator (also commonly referred to as a motor or turbine).

More specifically, in order to build efficient windmills for electricity you’ll need to find a generator that can produce a high level of voltage at a reasonably high current. The tricky part is finding one like this which can also operate at low revolutions per minute.

In terms of voltage you should look for something putting out more than twelve volts. As a general rule, residential windmills for electricity don’t spin at very high speeds, this is exactly why a high rated RPM generator won’t give you any kind of useful current.

The next part of the process involves building the actual frame and construction of the windmill. There are many options you can utilize here. For example you can make your own windmill blades or you can buy them. You can also try and source second hand parts from eBay or craigslist or buy them brand new from an alternative energy supplier. Whichever way you go will depend on your budget and also how willing you are to put in the effort to make your own parts. Most people who decide to do their own windmills for electricity will opt to build their own parts and this is definitely the best option considering how easy it is to make these parts nowadays.

You can manufacture the windmill blades from any sort of light weight material such as PVC tubing or fibre glass. Strong and light are the main criteria here. Pipes are good to use because they can be cut into a curved blade, which is preferable. Flat blades won’t be as good as the shape is not as aerodynamic and won’t generate as much spin.

As for the other parts, it’s mostly just pipes,tubes and wires. Once you make your propeller you attach it to the front of your main unit with the motor sitting just behind. It’s advisable to build a protective housing for the motor to protect it from the elements.  You also need to attach a decent sized tail to your mounting to steer the windmill into the right direction to get the most wind. Just think of it like an old fashioned weather vane (without the rooster!).

Most home made windmills for electricity are made to sit over eight feet high, usually much higher if you are mounting it on your roof or to some other solid structure. Free standing windmills for electricity will require you to some sort of pole or tube for your main unit to be mounted upon.

As this will be placed in a windy spot it’s also advisable to secure the unit with several guide wires fastened tightly to the ground in at least three directions.

You need to use a tubular support because you will need to feed the current from the motor at the front of your unit down into your base electrical unit.

Here’s the part where most people need help when making their own windmills for electricity, the electronics set up. If you don’t have a diagram of how this should be set up don’t even try it.  It’s a very complicated part of the process and if you do it wrong you could permanently damage your windmill project. You’ll need some detailed plans to build a small current controller. The parts required to put this piece together are all available at your local electronics store for just a few bucks. The purpose of this device is to essentially to route the power generated from the turbine into your batteries. The best batteries to use when building your own windmills for electricity are deep cell batteries, used in most home made energy projects like solar power generation. You’ll also generally need to set the controller to divert excess voltage into a back up storage cell, just in case your batteries become fully charged.
