If you are looking into buying wind kits, you have to do your homework before even thinking about buying anything. It is alluring to make your wind turbine buying decision based on what the turbine looks like. There are a lot of fascinating designs out there that don't produce that much power. The reason is the type of wind turbine you buy should be driven by what you are trying to accomplish with the project and the energy that is there to harvest. The different types and styles of turbines function better in certain environments than others. Also, space limitations often dictate the type of turbine you can use. So, the 3 questions you must ask before buying wind kits are: 1. How much electricity do I want or need to make? 2. What are the wind resources on my property? 3. Which type of wind turbine will serve me best? Come to grips first with how much electricity you expect to make. Before you do anything you must take some time and get your goals in mind. Would you like to power a small pump or your whole house? You can also export power to the electricity grid or, just charge a battery. Next, what are the wind resources you have available to harvest? The wind blows at different speeds and more or less consistently at different altitudes. Usually, at least 30 feet above the tree tops or above the highest obstacle is where the strongest and highest speed wind is found. However, it is expensive to mount a wind turbine on a tower 100 feet in the air. Also, for the amount of energy you are trying to create, you may find adequate wind resources on your roof. This is common no matter what the topography of your particular roof. Finally, study which type of windmill will work best for the job you want the wind turbine to do. There are 2 basic types available - Horizontal-axis - that looks like a classic windmill - and Vertical-axis - which spins vertically. Horizontal-axis wind turbines are the most efficient at producing electricity, without question. Vertical-axis turbines are a lot less efficient but they take up less space and are less stressful on your roof. In conclusion, for wind kits you need to do your homework first. Knowing clearly how much energy you need and how much you have to harvest will lead you clearly to the right wind kit to buy for your home.
