What We DoWhat We Do
AIR Breeze Whisper 100 Skystream 3.7
AIR is a 200-400 watt wind generator. More than 140,000 AIR’s have been produced over theLast 12 years
The Whisper line ranges from 900-3000 watts. Whisper’s are installed in more than 100 countries. Over 14,000 Whispers have been produced.
Skystream is a 2400 watt inverter based wind turbine. Introduced in 2007, to date, 7500 turbines have been installed throughout all 50 States
Battery charging ($600-900 USD) Battery Charging ($2800-7500 USD) Grid Connected ($6500 USD)3
The ProcessThe Process
Before a Project BeginsBefore a Project Begins
• Site wind resource• Property characteristics• Project economics• Utility interconnection agreements• Local Zoning/permitting
The quality of today’s wind maps are far better than those of a few years ago. Wind maps are used to determine the potential resource.

EconomicsEconomics
But…
The decision to invest in a small wind turbine or solar often is not solely about straight economics.
Economics – Reduce or eliminate monthly electric bill Control – Being less dependent on the utilityClimate Change – Concerned with environmental issues and wanting to make a statementNational Security – Concerned over the county’s growing dependence on foreign energy
1) Straight Payback2) ROI as compared to bank interest rates
Federal and State IncentivesFederal and State Incentives
9
State Incentives:1)State Tax Deductions2)Up to a 50% rebate in many States
Federal Incentives1)30% ITC for consumers2)30% for business as well as depreciation
Resources incentive database: www.dsireusa.org
State and Federal incentives can reduce the cost of a wind system by up to 70%
Utility InterconnectionUtility Interconnection Federal law (PURPA) requires that all utilities
allow customer-owned generators to interconnect with the grid
Most states have in place net metering and interconnection agreements
Off-grid systems do not need to notify the utility
The latest interconnection standard is IEEE-1547. The manufacturer must be able to provide a certificate
Resources: www.dsireusa.org (Provides list of utility interconnection agreements) www.irecusa.org (Provides examples of friendly interconnection agreements)
ZoningZoning
Most zoning districts do not have an established ordinance for small wind.
Changing or creating a new zoning ordinance can be a time consuming complicated process.
In order to drive local communitiesTo participate in state renewableMandates, some states are adoptingPreemption laws.
The Zoning Issue is The Zoning Issue is about towersabout towers
Towers are necessary to get the wind generator into the wind. Small wind generators must be installed on towers that are 25-30’ above any surrounding object within 300’ of the tower.
Typical tower heights for small wind generators range from 42’ to 120’
Restrictions in most counties limit tower heights to 35’.

ConclusionConclusion The first installation in a
place is always the most challenging.
Thereafter the process forfuture installs becomeseasy.
