Off Grid Wind Power Pricing and incentives
In Arizona, current incentives include a $1,000 tax credit for people who harvest electricity from the wind on their property.
Are
wind turbines right for me?
Wind
energy is not for everyone. Your site must have enough wind, and
be free from wind obstructions.
The site for your turbine must be free from obstructions within a 250 ft. radius, and you should be able to locate a tower where the top of it would be at least 20 feet above any surrounding object within that 250 foot radius.
The turbine must also be situated in a location with an average wind speed minimum of 9 MPH or about 4.2 M/S for your small wind system to be practical. There are different ways to determine if your site has enough wind resources.
Wind maps are available for most states. Most of these maps have a 1sq km resolution. Any data that is a class two or higher means you have enough wind at your site.
View the Arizona Resource Map.
Visit State Wind Resource Maps to see your state’s wind map.
Or you can check your local airport or weather station.
You can also look at the landscape and nearby trees for a fairly accurate determination of site wind speed. In areas of relatively smooth country, the winds are constant regardless of where you are. Hilly areas vary from location to location. Below is what is called the Grigs Putmum wind energy index. By looking at the trees on your property and how they may have been deformed by the wind, you can determine the resource in the area. Keep in mind, any data that is a class two or higher means you have enough wind at your site.
Wind power and solar power are complementary in the sense that when a wind resource is not available, sunshine often is. If both resources are available, then a hybrid system is the more economical approach. A hybrid system uses fewer batteries and the battery bank is cycled less, which results in longer battery lifetimes and lower costs. If you already have a wind turbine, consider adding solar panels to your system for extra dependability and long term cost savings.
ETA Engineering also carries accessories for Southwest Windpower wind turbines, including professional engineer certified tower kits, a variety of wind power and solar charge controllers and an assortment of water pumps.
