Cost

Installed, the Skystream 3.7 costs approximately $12,000 to $ 18,000 depending on tower height and installation expenses.  Price includes the generator, operation controls and inverter.  Skystream 3.7 has tower height options available to accommodate a location’s wind resource.  Skystream 3.7 is capable of producing energy at a fraction of the cost of other small wind, solar photovoltaics or reciprocating engine technology.  This is an accessible solution for the homeowner looking to reduce energy costs.

Savings

Depending on the installed price, average wind speed, local cost of electricity and state and federal rebates, Skystream 3.7 can pay for itself in as little as five years. In fact, a U.S. federal-level tax credit was just passed that will give up to $4,000.00 to consumers who purchase Southwest Windpower’s Skystream 3.7.

The overall energy produced from Skystream and corresponding savings is dependent upon a few key variables includes average wind speed, sitting conditions and cost of kWh. While output and savings will vary depending on these conditions the preceding graphs illustrate power generation and estimated energy savings over Skystream’s life. Based on an average wind speed of 12.5 mph approximately 5,000 kW/h’s will be generated annually. While energy production is linear based on fixed wind speed, the overall energy savings are not. The savings graph above shows the expected return based on a current kWh cost of 11 cents factoring in the expected increase of energy on an annual basis over the life of the turbine.
