Windterra is delivering a new paradigm for green energy – small wind turbines! No one has an “affordable” small wind generator for the residential and commercial markets. There are wind generation products, but they are usually Horizontal Axis Wind Turbines directed more towards farm/rural market, requiring a tower installation for greater speeds and laminar wind-flow.
The Windterra roof-mounted VAWT has a number of distinct advantages over costlier HAWT systems:
- VAWTs are omni-directional (can instantaneously accept
wind from any direction) as opposed to Horizontal Axis Wind Turbines (HAWTs), which have to constantly rotate so that they
are facing the wind.
- VAWTs are easily roof mountable and are
less affected by turbulent air than HAWTs, which make VAWTs far better suited for residential areas where obstacles such as
other houses and trees may disturb the airflow. Mounting the VAWT on a roof as opposed to a pole or tower makes the unit more
accessible for easy routine maintenance.
- Windterra's VAWTs
rotate at a much lower speed than the very high speeds of existing HAWTs (225 rpm versus 900 rpm), resulting in much lower
noise levels and vibration.
- Windterra’s inverter technology
provide efficiencies at lower voltages (lower wind speeds) not seen anywhere in the industry.
- Windterra's control system allows the turbine to operate at its most efficient level throughout
the wind velocity range (dynamic loading). This ensures that the turbine is always producing the most energy possible for
a given wind speed without overloading the turbine.
- Our blade
design optimizes the turbine’s performance at typical lower wind speeds. Most designs concentrate on rated wind speed
and rated power, which yield a lower annual power output at typical wind speeds. Windterra’s designs focus on generating
the most amount of power at typical wind speeds. The result is a higher annual power output - this is what is important to
the consumer - annual power output, not rated power!
- Windterra’s
products will incorporate grid-tie, solar inputs, as well as optional battery charging capabilities.
- Windterra’s ECO1200 is a complete "all-in-one" wind turbine system, which includes the turbine, controller/inverter, and mounting system.
What is the ECO 1200 output/year?
The
output would be 1,642 kWh per year in 5 m/s (11.18 mph) mean wind speed, using Rayleigh Distribution of wind (the recognized
method of calculating annualized output of the turbine).
What is the average electrical consumption of average home/year?
The average household consumes 9,000 to 12,000 kWh /year.
What is the effect of the ECO 1200 on carbon footprint reduction on an average home?
Based on the U.S. average fuel mix, approximately 1.5 pounds of CO2 is emitted for
every kWh generated. Therefore the ECO 1200’s annual production of 1,642 kWh would save 2,463 lbs (1.12 tonnes) of CO2
emissions per year.
What regulatory approvals have been achieved?
UL Listed to UL 1741 Inverters, Converters, and Controllers for use in independent power systems; CSA 22.2 No 107.1
Standards Commercial and Industrial Power Supplies.
How easy are they to install?
It
will take two professional installers approximately five hours to complete most installations. Do-It-Yourselfers can get the
job done in a weekend, or less. We always recommend that you use a licensed Electrician for the grid-tie connections.
The standard limited warranty on the units is three years. Since these units do not have a gearbox, they are relatively maintenance free. It is recommended that they be inspected every six months.
Do you need to buy the tower, electronics, and other components separately or are they
all included?
Everything that is required to mount the unit on the
roof of a residential or light industrial building is included. Additional wiring and small parts will be supplied by the
electrical contractor who connects the system to the electrical panel of the home or commercial building.
