Air 40 12V Wind Turbine, energy for cabin, home or remote location

Air 40 12V turbine
  • Air 40 12V Wind Turbine #BP4920125
  • Wind turbines operate by capturing the kinetic energy of moving air. Air 40 12V wind turbines efficiently capture the power of the wind and converts it to rotational motion to turn an alternator that produces electrical power. The electrical power must be regulated to a voltage to charge the system batteries, and there must be a system to prevent overcharging the batteries and resume charging as the battery voltage drops. A means to protect the Air 40 12V wind turbine from extreme wind damage must also be provided. The Air 40 12V wind turbine accomplishes all these goals by incorporating a three-phase brushless permanent magnet alternator and microprocessor controlled electronics to optimize its power production capability. The microprocessor continuously adjusts the loading of the alternator to keep the turbine operating efficiently. The result is the Air 40 12V has high power production, high blade efficiency and lower blade noise.

Air 40 12V wind off-grid turbine allows you to capture mother nature’s power and convert it into clean, dependable power you can use in areas where the power grid doesn’t reach. Whether you’re generating energy for a remote cabin, sailboat, RV or offshore platform, Blue Pacific Solar has a wind turbine to fit your energy needs and wind conditions. You also may find that combining wind power with solar can create a perfect complementary system for keeping your batteries charged.

The sound from small wind generators, like the Air 40 12V wind turbine, typically blends in with common outside sounds like those from cars, airplanes, barking dogs and wind blowing through the trees. According to the U.S. Department of Energy the sound pressure level generated by a small wind generator is in the range of 40-65 decibels which is quieter than background noise in a home or office. Air40 12V turbine sound is unrecognizable over trees blowing in the wind.

Air 40 12V wind turbines, like similar small wind generators, are installed on towers similar those commonly-accepted in communities across the country and don’t look much different than a common light pole or radio tower. The Air 40 12V wind turbines, like other small wind generators, are installed on towers ranging from 35 - 110 feet tall and have blades ranging from 3 - 6 feet in diameter, they don’t look much different than a common light pole or radio tower. Southwest Windpower generators are designed to minimize the visual area and preserve the horizon.

As with any structure, Air 40 12V wind turbine and tower must meet local building and safety requirements. Towers are installed according to manufacturer and local zoning specifications that ensure structural safety. Small wind generator towers pose no greater climbing risk than other similar poles and towers or even trees. Many wind generator towers have a smooth surface, like a light pole, that is nearly impossible to climb. Those towers that are climbable can be equipped with devices that prevent falls—as with other climbable towers.

The Air 40 12V wind turbine has no effect on TV or communications signals, as the blades of the Air 40 12V wind turbine are made from materials that signals can pass through. Nor will the Air 40 12V wind turbine electromagnetically interfere with telecommunications or radio waves. In fact, one of the major markets for the Air 40 12V wind turbine is powering remote telecommunications sites often time as a part of a solar hybrid energy system.

There are as many as 20,000 small wind generators installed every year and to date, there has been no documented evidence that small wind generators, like the Air 40 12V wind turbine, or even commercial wind farms have ever lowered neighborhood property values. In fact, a 2003 study that examined property values near ten wind farms found that property values rose faster in those areas as compared to other homes within the region. According to the American Wind Energy Association (AWEA), a survey of 300 California homeowners conducted for the California Energy Commission found that 50 percent of homeowners surveyed “would be willing to pay more for a home equipped with solar and wind technology.” The same study found that 60 percent of homeowners surveyed “would be more interested in a home that has a renewable energy system already installed versus a home that does not.” Also, informal surveys of property values around three small windmills in New York showed that the asking price for most property near residential wind generators was higher than the assessed value.

NOTE, IMPORTANT INSTALLATION SAFETY AND CODE COMPLIANCE: (OK, here is the scary legal disclaimer.) It is the responsibility of the purchaser to ensure that all Air 40 12V wind turbines are installed and operated in accordance with local and national building codes as specific by the NEC (National Electric Code), UBC (Uniform Building Code) or IBC (International Building Code) and local utility company policy. These codes may vary from city to city and county to county. All Air 40 12V wind turbine home installations should be permitted and inspected, where required, by the local inspection authority in the same manner as other equivalent electrical systems.
