The consumption of home established wind turbine power has become a really popular item in a lot of homes. More and more people across the world have come across the idea of the economic value of applying such a way to produce energy. This is because they want to freely use the energy for their daily domestic needs. This is also because energy produced by the wind turbine saves us a lot of money of the m monthly electricity bills as well as it also has the potential of being used as a means of earning some money at the same time. The investment to be made for installation of the wind power turbine is not so much compared to the increasing rise of the cost of the electricity bill we have to pay. The investment made is bound to recoup itself within a few months or so.
Before setting up a wind turbine, the following study should be conducted and a feasibility report prepared and studied well before going ahead with the installation. The company from whom you will purchase the equipment and also install the wind turbine should be able to prepare a wind turbine feasibility study which should consider the following aspects before setting up the turbine.
The first and foremost thing that must be taken into account is the site where the proposed wind turbine is going to be set up. Wind turbines should be set up in only those sites where the average wind speed is 20 miles per hour because this will generate twice as much power as a site where the average wind speed is only 15 miles per hour.
The property where you have decided to set up the turbine should be free from obstacles. Ideally the turbine should be set up in a higher place at least thirty feet above any obstacles and should also have at least 300 feet clear area around it.
The wind in the site should have consistency and stable high speeds because instability can put extra stress on the tower and other turbine parts. The site chosen should be preferably at a little distance from residential areas and should be properly fenced and warning signs affixed at different places around the site.
The environmental impact that is likely to be caused should also be studied. The animal habitats nearby should be taken into account as there is some unfounded prejudice against wind turbines over deaths of small birds, which is however negligible. The zoning bylaws and other restrictions related to the situation of the wind turbine should be also be taken into consideration during the study of the feasibility of setting up of the wind turbine.
As the normal life expectancy of a small wind turbine is about 15 years, the economic impact it may have on your budget towards its maintenance and replacement of parts should also be considered. However the maintenance needs of small wind turbines are negligible, once it is properly installed by a reputable company.
Today wind power has become another source of energy in addition to the other sources of energies that are now presently used. To learn more about wind power and wind turbine feasibility study, the help of the internet can be taken for searching more information on the subject. You can also take the help of the internet in finding out a reliable company for conducting an effective wind power feasibility study because this is one of the most important factors to be considered, before setting up a wind power turbine.

Are you getting frustrated with rising energy costs? Have you been thinking about building a small residential wind turbine? You’re not the only one. Given the increased price of conventional power sources, many people are considering the benefits of making their own wind generator or turbine. Before embarking on this venture however, there are a few things you should educate yourself about.
Determining how a home turbine works, what you’ll need to build one, and where to get those items from ahead of time will save you money, time and frustration. It is important to make sure you understand the basics of a home wind power generating system long before you get started. Familiarizing yourself with the individual components that make up a home wind power system will decrease the likelihood that you will lose time and money to problems that could easily have been avoided by doing your homework ahead of time.
One of the first and most important things to consider is where you’re going to build your turbine. Of course you need to have the room on your property, and in addition you need to determine the most optimal spot in terms of being able to capture the largest amount of wind power. Typically this will involve being far enough away from any obstacles that could block wind flow to the turbine. Another important aspect of locating a site for your wind generator is that the location must meet the local zoning requirements of your town or municipality. You don’t want to skip checking on zoning rules and end up making a mistake that will cost you money and time. So first, contact your local or state zoning agency and then within those confines determine the optimal site in terms of wind and the features of your available property.
The next thing to consider is the tower that will support your wind turbine. The tower needs to be tall enough to place your turbine in wind that is strong enough to generate sufficient power and the higher you go, the more power you’ll generate. However the higher you go, the stronger your tower will need to be and the greater the cost will be. Remember you want your wind turbine to remain standing even in the face of hurricane force winds. Another reason to limit the height of your tower is that as you go higher the increase in wind power won’t pay off for the increased cost of your tower. The tower can end up being the most expensive part as it the biggest. Thus you can see that it makes good sense do your homework ahead of time. This is true whether you build your own and purchase a tower. Keep in mind that if you build your own, there may be liability issues so consider this drawback and weigh it against any extra cost of simply buying a manufactured tower.
Getting started on building your own wind turbine system can seem daunting but with proper preparation you can avoid running into trouble by addressing issues such as those discussed above before you begin.

Design Features
Advanced over-speed control mechanism vs. old style furling
Problems with old style furling: Old style furling works well in an ideal, wind tunnel test environment. Realistically, wind speed and wind direction changes frequently and mechanical furling doesn’t have instantaneous response to actual changes of wind status. Especially in bad weather conditions, small wind turbine furling components wear out quickly, therefore, increases maintenance costs and shorten wind turbine service life or causes system failure.
Most of old style furling based wind turbines have three moving parts. It is the moving parts for mechanical over-speed protection that wear out and require a lot of maintenance. Operation of furling based wind turbines would lead to mechanical abrasion, cause vibration, malfunction, and failure of the wind turbine and other devastating results in the long run.
The rule of thumb for a reliable wind turbine is that the fewer the moving parts, the more reliable the wind turbine is.
The Windmax Solution: Windmax H series adopted Innovative over-speed control so it improves the reliability by abandoning the moving parts for mechanical over-speed protection and minimizing the moving parts to only two.
Innovative over-speed control design of the Windmax H series: The Windmax H series speed limitation abandoned the traditional failure-prone mechanical furling system and solved safety and reliability problems facing most small wind turbines. Advanced speed limitation of Windmax H series is achieved through advanced electromagnetic speed limitation supplemented by aerodynamic speed limitation by blade deformation. Electromagnetic braking is used in combination with Aerodynamic braking to reduce the rotational speed of the generator.
Combination of Electromagnetic braking and aerodynamic braking maximizes energy capture by extending Windmax H series turbine’s operating speed range into higher speed winds and lower speed winds which are missed by the old style wind turbines.
1. Electromagnetic speed limitation:
Controller will monitor the wind generator rotation through the wind generator output voltage and frequency, and will timely control wind generator rotation by generating reverse reluctance torque if necessary, according to different wind conditions and battery status. Electromagnetic control features quick response, high reliability and therefore ensures the entire control system to be highly reliable.
2. Blade aerodynamic braking:
In high wind speed conditions, patent pending blades will generate a reverse reluctance torque, so that the blade efficiency falls and the blade rotation speed starts to decline. With the continuing reluctance torque, blade rotation speed is limited to a certain range to prevent damage to the wind turbine blades.
Wind-solar hybrid power generation wind turbine system
Problem with single source renewable energy system:
1st Generation single source renewable energy systems such as solar systems or wind turbines don’t use renewable energy efficiently. Wind turbines creates less output during the summer, whereas during the winter the solar panels will produce less output.
Windmax Solution:
Our Windmax hybrid solar-wind turbine integrated wind and solar power sources capture the most energy in all conditions. Since solar and wind energy availability differs by locations, seasons and climates, solar and wind energy can be mutually complementary in that solar and wind hybrid systems make full use of wind and solar energy together to generate as much power as possible compared to a single energy source for power generation. A solar & wind hybrid system is more cost-efficient than wind or solar alone.
Easy-to-install, light weight, compact, reliable and maintenance-free wind turbines, designed for both land-based and marine applications.
Problem with old style wind turbine systems:
Most old style wind turbines are heavy weight with unpredictable reliability, hard to install and require lots of maintenance. Due to the fact that most installations are in very remote and inaccessible locations, the old style systems make regular maintenance costly and sometimes impractical.
Windmax Solution:
Windmax H series maintenance free design has a minimum of moving parts with inherent reliability. Our light weight, compact die-casting aluminum alloy generator design makes installation very easy. Rotor blades built with latest advanced thermoplastic engineering and precision injection molding technology is durable and efficient.
Higher performance at low wind speed
The problem with small wind turbine system on the market today: The most challenging problem facing small wind turbine systems is that power output is very low or close to nothing under low wind condition. The wind speed in most locations don’t stay at rated wind speed all the time, wind turbine actually operates at wind speed lower than rated wind speed at most of the time. In order to have good overall energy output, it is critical for small wind turbine to output as much as power at low wind speed.
The WindMax Solution: Strong Neodymium magnet PMA, unique winding and multi pole design reduces the start-up torque of the alternator that assures the WINDMAX-H series can generate electricity at low wind speed. WindMax system components such as wind generator and blades are designed to output more electricity at low wind speed than other small wind turbines on the market today. WindMax system’s excellent power output under low wind speed results in greater energy production yield and lowest ownership cost.
WindMax H series components are built with advanced technologies
Generator: The generator is built using high-performance rare earth neodymium permanent magnets, so the alternator is compact and light weight with a high power generating efficiency. The unique winding and multi pole design reduces the start-up torque of the alternator that assures the WINDMAX-H series can generate electricity at low wind speed. The generator features class B insulation, IP55 class protection, and is designed with a sufficient cushion of overload to ensure overall wind turbine reliability.
Generator housing is made with precision cast technology from high strength aluminum to assure a high quality finish. It is designed for various working conditions such as severe climate, sand and salt corrosive environments and marine usage. Aluminum die cast alloys can withstand the highest operating temperatures of all die cast alloys. Ideal for demanding environments, it offers high strength and rigidity along with good corrosion resistance and heat dissipation.
Patent pending Rotor Blade design vs. traditional hand made fiber glass blades: Our Blades are made with the latest thermoplastic engineering and injection mold technologies. The blades are made of mixed reinforced fiber glass and nylon materials. These manufacturing technologies ensure the highest strength, flexibility of blades and consistency of the blade shapes. The blades will automatically slow the turbine in strong winds and reduce noise.
