Calculating the size of your system
The size of the system you need depends on several factors:

  • How much energy usage you want to offset
  • Available space for the system
  • How much you want to spend

Wind Generation Systems

Wind generation systems are more difficult to site due to the variability of the wind resource. The background information necessary to size a system and estimate annual output requires more detailed analysis of the site. For a detailed evaluation of the cost estimates and sizing, please contact a local wind generation vendor or contractor.

Hydro Generation Systems

Hydro generation systems require approval from the Washington State Department of Ecology. For more information, please visit the Department of Ecology website.
