How to Build Your Own Small-Scale Wind Turbine from Scrap Materials


Building your own small wind turbine from scrap materials can be a fun and rewarding project. Wind power allows you to generate electricity from a renewable resource, the wind, making it an excellent option for sustainable and eco-friendly energy generation. With some basic materials, tools, and skills, you can build a functional small wind turbine to power small electronics, charge batteries, or even contribute electricity to your home's power system.

In this comprehensive guide, I will walk through all the key steps and considerations for designing, sourcing materials, constructing, installing, and maintaining your own DIY wind turbine. Whether you want to build a small turbine for an outdoor lamp, trickle charger, or a more robust grid-tied system, this guide will provide all the information you need to successfully build your own wind generator from scrap parts.

Choosing a Design

The first step is deciding on the design for your wind turbine. The design will determine the size, materials, complexity, and performance capabilities of your system. Here are some of the main options to consider:

Vertical vs. Horizontal Axis

For small DIY turbines, a horizontal axis design is typically easiest and most efficient.

Number of Blades

Blade Pitch

For DIY builds, fixed pitch is recommended for simplicity.


For first DIY turbines, an open blade design is advised.

Sourcing Materials and Parts

One of the benefits of DIY wind turbines is they can be built using scrap and salvaged materials. Here are some of the key components you will need and suggestions for sourcing them affordably:






Use creativity and available resources to source scrap materials at low or no cost for your components.


Once you have components and designs selected, it's time to start building. Here are some key steps in the construction process:

Cutting Blades to Size

Assembling Hub

Mounting Generator

Installation on Tower

Take safety seriously during construction and assembly. Use appropriate protective gear, rigging, and common sense.

Testing and Troubleshooting

Prior to full operation, the turbine should be tested to identify any issues:

Don't hesitate to take the turbine down, inspect components, and make adjustments until satisfied with performance. Safety is paramount.

Installation and Wiring

For permanent installation:

Proper siting and wiring are essential for efficiency, safety and longevity of your turbine.

Operation and Maintenance

Once successfully installed, your wind turbine should provide years of service with some periodic maintenance:

Implementing sound operation and maintenance procedures will maximize the lifespan and productivity of a DIY wind turbine.


Constructing your own small wind turbine from scrap materials is an immensely rewarding project requiring skill, patience and persistence. Follow the guidelines in this article for choosing designs, finding parts, assembly, installation and maintenance. With some care and creativity, you can build an efficient and lasting wind turbine to generate free electricity from the wind for your DIY projects or homestead.
