These systems connect to your household wiring, just like a large appliance.

They work cooperatively with your utility power.  Often you will be getting some power from both the wind turbine and the power company.

If there is no wind, the power company supplies all the power needed.

As the wind turbines begins to work the power you draw from the power company is reduced … causing your power meter to slow down.  This reduces your utility bills.

If the wind turbine is putting out exactly the amount of power your home needs, the power company’s meter will stop turning.  At this point you are not buying any power from the utility company.

If  the wind turbine produces more power than you need it is sold to the power company.  In California your utility meter will actually turn backwards and the excess energy is effectively "banked" for your use later in the year.

No changes in the household wiring are needed.  It is very easy to add these systems to an existing home.

The most cost-effective systems do not have batteries and they can not supply power during utility power outages (Bergey GridTek).  Systems that can supply back-up power during outages are available, but at a higher cost.  For information on them click here (Bergey Home.Sure). We recommend the GridTek battery-less system in most situations where your home already has utility service.

A typical 10 kW Bergey GridTek home wind energy system will cost $40,000 - $60,000 to install, depending on the tower option and various installation factors.  Depending on the wind resource they will produce between 8,000 – 18,000 kWh per year.

NYSERDA offers subsidies ranging from 50% to 70% when you install a system.  You will actually receive a check!

A home sized wind turbine is big:  21 foot blade diameter and a 80-120 foot tall tower.  We recommend a minimum property size of 1 acre.

Some areas do not have a sufficient wind resource.  In general, we recommend a minimum wind resource of DOE Class 2, which means the annual average is 4.5 m/s (10 mph) or higher.

Here at our web site you can determine whether a Bergey wind system is feasible at your home or business ... and you can even learn how to buy it factory-direct and install it yourself!
