The vertical axis wind turbines have certain advantages over the traditional horizontal axis wind turbines. They are able to catch the wind from any direction without the need for a yaw mechanism. They're quieter, and are generally better for birds. They have a lower center of gravity and are easier to install on rooftops, towers and rural properties. Currently vertical axis turbines are being utilized in the USA for distributed energy generation by homeowners, farmers and small businesses.
Key Features to Look for in a Vertical Axis Turbine
Before looking at models, it's important to know what constitutes a quality vertical axis turbine. First look for materials of construction that are durable like aluminum alloy or reinforced fiberglass, which will stand high winds and weather extremes. Second, determine the generator type. Permanent magnet generator and disc coreless generators offer high efficiency and low maintenance. Third, take into account the blade design. Blades are aerodynamically designed to extract more energy over a larger wind speed range. The fourth step is to inspect the braking system. The wind controller is very important and must be reliable and have an overspeed protection. Fifth, check claims for power output. DHC guarantees actual performance where no inflated figures exist, and our customers know what to expect.
The Off Grid Small Turbine for Remote Cabins
A small vertical axis turbine (VAT) that delivers 300W to 1kW is suitable for off-grid cabins and tiny homes in rural America. The small turbines can be installed on a short pole or even on a strong rooftop. They operate without any noise, and begin to produce electricity at wind speeds as low as 2 to 3 meters per second. They can be paired with a LiPo battery pack to store energy for use when the sun is not shining or wind is not blowing. DHC provides these turbines with an integrated wind controller to avoid overcharging the battery. The off grid wind system configuration is designed to make properties energy independent, without having to rely on noisy generators or costly grid extensions.
The Rooftop Rated Turbine for Urban Homes
Homeowners in windy urban areas such as Boston, Chicago, and San Francisco are now discovering vertical axis turbines that can be installed on their roofs. Vertical turbines automatically adjust to wind direction at any time and do not need to be oriented into the wind to function. A small wind turbine (SWT) with a capacity of 1kW-2kW installed on a flat roof can generate enough power to cover a substantial amount of a household's consumption. Low vibration and quiet operation are key in a residential application. Using the disc coreless generator technology, DHC's vertical axis turbines have reduced cogging torque and noise. It can be used with a solar heat pump system and a high voltage LiFePO₄ battery to achieve near-zero energy bills for the home.
The Heavy-Duty Turbine for Commercial Buildings
Commercial buildings like warehouses, retail centers and offices have high roof surface areas and large electrical loads. A 10kW to 20kW vertical axis turbine can provide a significant contribution to on site renewable generation. These larger turbines are designed with thicker blades, stronger bearings and are able to withstand years of continuous use. They often have built-in remote monitoring functions via a wind controller with data logging. DHC's commercial-oriented turbines are part of our on-grid wind system offerings, allowing excess electricity to be exported to the utility through net metering. Organizations can boost their sustainability and reduce operational costs.
How to Choose the Right Turbine for Your Application
There are several factors involved when choosing the optimal vertical axis wind turbine. Use online maps or an on site wind anemometer to determine average annual wind speeds. Work out the energy you use per day in Kilowatt hours. Decide on the type of wind system – off grid or on grid. One idea would be to install the turbine along with solar panels and a LiFePO₄ battery. The most significant factor is to work with a supplier that is honest. DHC's business is based on the principle:"Quality is the foundation, and customer-centric service is key.” All products we offer guarantee actual power output-no oinflated ratings.
