Rooftop Design / September 8, 2018 / Juan M. Tate
Critics of rooftop wind turbines say that they simply dont work or dont work as well as advertised. The critics are right in some instances and that is why the consumer needs to know what they are getting into and what to watch out for before investing in a rooftop wind turbine. Some of the factors that will influence the output of the rooftop wind turbine include the design itself (horizontal or vertical axis) the kilowatt rating of the generator where the rooftop wind turbine is placed the angle or pitch of the roof how much wind the region provides and any obstructions that may block the wind.
Some rooftop wind turbines will work more favorably when on the edge of a rooftop such as one that is long and flat (sort of like being on the edge of a cliff with an updraft). Others however on roofs with more angle or pitch will work more favorably in a higher location. Finding the right spot on the rooftop can add 5 to 40-percent more efficiency in electricity generation. One of the most obvious points is for home and business owners in rather windless areas to not buy rooftop wind turbines but rather opt for other alternative energy resources. Wind maps may help some determine if there is enough regional wind to justify the purchase of building of a rooftop wind turbine. Buying an inexpensive anemometer and tracking results is also helpful before making a decision.
Near homes neighbors trees grow and leaf out people may put up a second story or business may build structure in close proximity to homes which all may impact rooftop wind turbines. The important thing is to think about as may variables as possible when deciding if a rooftop wind turbine makes sense and the location that fits well.
