* We make the following assumptions in addition to those you may choose to change above

• Illustrative turbine performance figures only. Figures are given in good faith but do not constitute "Financial Advice".
• Exact Turbine subsidy figures may depend on grants available at particular locations and other factors.
• Windspeed and elevation data is our interpretation of data modeled at specific points by a number of data providers.
• Rotor heights shown are for a ground upward measurement, unobstructed by buildings or trees in the nearby vicinity
• Tariffs shown presume installation between 1 August 2011 and 31 March 2012.
• Yearly output does not include a calculation for degradation over time
• Only currently MCS certified turbines are shown. Other turbines exist and may gain accreditation in the future
• Turbine technical information uses data supplied by a number of sources which may include the manufacturer
• Installation costs will vary, an average figure has been estimated.
• Exact equipment costs are estimated based on retail prices in 2011 and will vary.
• You should consider other factors such as sound, appearance, and localised factors prior to making a decision
