DIY Wind Generator: Basic Facts About the Ideal Solution
Wind generators are perfect if you live in a windy place or your solar panels are no longer enough to cover your energy needs. But before you start buying the materials for one, it’s imperative that you do a wind assessment test beforehand to see if the wind current is enough to produce the desired output. Without these tests, the risk of ditching the entire project and losing your initial investments are at an all-time high.

First, you need access to GIS (geographic information system). These are public data sets collected and maintained by the US National Renewable Energy Laboratory. Using their specialized tool, the said data sets can be used to calculate the potential amount of electricity that can be produced within the area of concern. Once you have the green signal to build a wind generator, the next task is to know the right resources or manuals to start out the project.
If you want to save money, consider building your own wind generator; the cost of finding your own materials than buying a ready-made windmill is comparatively lower. The only obstacle you will be likely to face is when the manuals are not readily available, or you are not a technically-inclined person.
To build a wind generator, you will need the main parts such as the blades, DC motor and the mast, all of which can be purchased from your local hardware stores. You also need batteries where you store the generated energy. If the budget is limited, use recycled batteries instead of buying new ones.
The majority of today’s homemade wind generators are built in horizontal axis. This is a popular design, and you see lots of them when you go to the countryside or farms. Since the blades rotate horizontally on an axis, a mast or vertical tower is needed to hold the whole structure. Ideally, the higher the mast, the faster the wind and the more energy can be generated. However, in real practice, this isn’t feasible for a homemade one due to the cost of building a mast to support it.
A better solution would be to build multiple smaller units outputting just 1000 to 3000 watts rather than one complicated and pricey wind structure. A single unit cannot supply your entire power needs, but eventually, as you build one generator after the other, you will be able to cover all your energy needs.
Most wind generators consist of 2 to 4 blades, which is already efficient in terms of power generation. Two blade turbines are generally cheaper but are less efficient while having four blades are the best but are costly. Either way, building a wind generator can save you lots of money over time, and will let you go green while doing it.
