Self-built Small Wind Turbine

Country:
Worldwide
Why to choose this solution?
Provided that favorable wind resources are in place, small wind turbines can deliver considerable benefits for individuals or small communities; relatively easy to build, they can deliver important amounts of energy which can be used for a large variety of applications, from battery charging to powering equipment. Compared to PV (Photovoltaic) panels, they operate also during the night and in winter, when the sun is weaker in many regions of the world. Additionally, they do not require an inverter, since the electricity delivered is already DC.
Savings per day or production:
Difficult to estimate, since it depends a lot on the weather conditions where the wind turbine is installed; however, once installed in the correct location, the wind turbine can deliver electricity for several years.
Cost in money and in own time to construct:
An average cost of 200 to 1,000 Euro should be expected when using quality components, but the final cost can be lowered if recycled materials are used. Additionally, cheaper solutions can be found online, but the quality of the product deliver is not always matching the requirements.
Lifetime:
If built correctly, the small wind turbine should last a minimum of 15-20 years.
Maintenance needed:
Limited
Resources needed in use:
Wood, steel, copper wires, magnets, bearings, epoxy resin (or equivalent).
Problems and limits:
Although the construction can be done by anyone, a certain knowledge of handling tools is required. Furthermore, some countries might need to install the turbine on a high tower due to limited wind resources.
Where and how can you get it or make it?
A construction manual can be purchased online: https://pureselfmade.com/
Skills needed to produce, install. maintenance, use:
Knowledge of working with tools and someone to instruct (or a manual).
How to use it:
Not relevant
How to maintain it:
Not available
Climate effect (if any):
The installation and usage of a wind turbine means that electricity can be produced freely for the whole lifetime of the turbine. This means that less or no diesel generators should be used, resulting in a considerable reduction in emissions.
Where it is used and how many users are there?
Widespread around the world.
Why is it successful?
Easy to build and simple model, which allows fulfills the needs of those who install it.
If you can make it, a short description, typical problems, materials needed.:
A manual should be followed or a course attended.
How to make it (if possible):
Not available yet
How is it delivered and by whom?
Materials are quite basic and can be purchased everywhere.
Successful financial model
