Wind power can be used in off-grid systems, also called stand-alone systems, not connected to an electric distribution system or grid. In these applications, small wind electric systems can be used in combination with other components – including a small solar electric system – to create hybrid power systems. Hybrid power systems can provide reliable off-grid power for homes, farms, or even entire communities (a co-housing project, for example) that are far from the nearest utility lines.Off-grid systems, also called stand-alone systems, are not connected to an electric distribution system or grid.

 

Hybrid wind energy systems can provide reliable off-grid power for homes, farms, or even entire communities (a co-housing project, for example) that are far from the nearest utility lines.

 

An off-grid, hybrid electric system may be practical for you if the items below describe your situation:

 

You live in an area with average annual wind speed of at least 9 miles per hour (4.0 m/s).

A grid connection is not available or can only be made through an expensive extension. The cost of running a power line to a remote site to connect with the utility grid can be prohibitive, ranging from $15,000 to more than $50,000 per mile, depending on terrain.

You would like to gain energy independence from the utility.

You would like to generate clean power.
