Vertical Axis Turbines was created by Elliot6782
I am doing analysis comparing the energy generation and financial viability of diffent types of wind turbines. I have created my own power curves for models not contained within the default library. My questions are:
1 - Do the inputs differ for vertical axis wind turbines? I want to make sure that SAM is accurately taking into account the swept area and ability to make use of winds from various directions.
2 - Related, if my horizontal axis turbines have a yaw swing to orient itself into the wind, how can I take that into account?
Thanks.

SAM calculates the wind turbine output using the power curve data and data from the weather file (wind speed, ambient temperature, atmospheric pressure, and elevation above sea level). You can use a power curve for any type of turbine.
SAM does not account for yaw, pitch, swept area, or other factors that may affect turbine performance. It assumes that the turbine performs according to the power curve regardless of the wind direction.
For a wind farm with more than one turbine, SAM uses the wind direction data and distance between turbine values to estimate the effect of turbines blocking wind flow from each other on the wind farm's output.
