What is unique about Windterra?s products??

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.

  Q. How is solar electricity generated?
  Energy from the sun can be directly converted to electricity using solar cells, also  known as photovoltaics or PVs. PV modules are manufactured with varying electrical  outputs ranging from a few watts to more than 100 watts of direct current (DC)  electricity.

  Q. What are ?PVs? (photovoltaics)?
  A solar or PV cell consists of semi conducting material that absorbs the sunlight. PV  cells are typically combined into modules that hold about 40 cells - About 10 of these  modules are mounted in PV arrays.

  How is electricity measured?
  Electricity is measured in units of power called watts. One watt is a very small amount  of power. It would require nearly 750 watts to equal one horsepower. A kilowatt  represents 1,000 watts. A kilowatt-hour (kWh) is equal to the energy of 1,000 watts  working for one hour. The amount of electricity a power plant generates or a customer  uses over a period of time is measured in kilowatthours (kWh).

  Q. Can solar power work in Oregon?
  Yes. Solar electricity systems that are tied into public utility systems sell power back  to the utility grid when production from renewable energy harvestment systems exceed to  energy consumption, with the advancement of solar technology, solar panels are still able  to collect energy on cloudy days. The result is less dependence on non-renewable energy  and more clean power from wind and the sun.

  Q. How does a solar electricity system sell power back to public utilities?
  If you are connected to a utility and wish to produce your own electricity, Oregon's "net  metering" law (ORS 757.300) requires utilities to let you exchange any surplus power  produced by your solar electric system for utility power you use when your system is not  producing enough power to meet your needs. Your meter simply spins backwards during sunny portions of the day when you are producing more than you use. At the end of the billing
  period, you are only billed for the net energy you use.

  If I install a grid-tied system now, can I put battery-backed system onto it later?Battery-backed and grid-tied only systems use the same solar panels; The difference is replacing the power inverter and purchasing the addition of batteries.

  How can I tell if my building is suitable for Photovoltaic Panels?
  Several aspects will need to be evaluated to determine if your home is a good solar site, such as orientation, space available, shadows on the space available and your current  electricity usage. The best site will be one with adequate south-facing roofs that have  no shade.

  What costs are involved?
  Costs involved are the cost of the PV panels and hardware, installation, electrical  building permit, conduit, miscellaneous wiring. For an up to date price quote, please  call us at (971) 218-2564 or email to geodescentgarden@gmail.com
