Seventh Wind Calculator - Small wind performance tool
The Seventh Wind Calculator is the chosen tool of wind site assessment certification courses. The calculator addresses the main question that project visionaries have when they approach an opportunity. How much energy will this system produce when it goes online. How much energy will the wind turbine produce under site specific conditions?
Our calculator includes more than 50 systems of manufacturers who have provided third party verified power curves. Factors of tower height, wind resource, and the shear affect are taken into account.
Because All Energy is Not created equal
With so many options in today's marketplace, it's essential to have an accurate and reliable tool to calculate which wind turbines will perform well at your site and meet your energy production goals. After all, installing a wind turbine is a big investment. You want to make the right choice the first time.
This is why SeventhWind was created.
For over five years, SeventhWind has been providing critical performance data to wind site assessors, wind turbine installers, educators and state funding agencies. The software is popular because on the front it is very easy to use and it is trusted because behind the scenes it utilizes the most current technical data available.
