With all the devices out there that are competing for our attention and money, it is not surprising that most potential buyers of turbine kits products question whether they really work or not. Without question there are number of these devices out in the marketplace that don't and just as with any new area of science, there are pirates selling them that are intent on stealing your money. So, how is a consumer supposed to know the difference between a good turbine kit and a bad one? There are 3 things to look for when you are evaluating these devices... Upfront cost - these turbine kit products can really range in cost. There are some that are under $1000 and some that are many multiples of that. One thing to pay particular attention to is how aesthetically styled they are. The ones that are meant to blend in with the roof environment for example, are a lot more expensive. What components does it come with - if you are needing a set of batteries, that is not a typical component to be included with the kit, nor will the tower to mount it on. Make sure what the shipping manifest will contain before sizing up the price of a home wind turbine kit. Those components just mentioned can more than double the upfront cost of the project, so if you are going to need certain things to make power at home work for you, it is best to sort all that out before you buy. What is the cut-in speed - this is the speed that the rotors start turning and making power. The cut-in speed is of course different with every wind turbine out there. It is a factor of the weight of the blades and design considerations that limit the speed of the shaft to keep the wind turbine from over-speeding in high winds or gusty winds. When a designer is coming up with a proper low speed level they are having to make sacrifices on the amount of power that can ultimately make in a strong wind environment. Also a low cut-in speed will limit the rotational inertia of that can be achieved through more substantial materials. In summary, a turbine kit will technically work almost no matter what if all you are asking it to do as long as it is just turning to make power. The challenge becomes finding one that will efficiently make power and make it for a long time without having to be constantly repaired by a professional.
