## Explanations for the power calculator

With the power calculator you can estimate the power production for a site for different turbine types. A turbine availabiliy of 100% is assumed (no losses due to down time, icing, transformer losses, park effects etc.). No guarantees can be given for the obtained results.

^{1} The capacity factor is the ratio between the annual production and the maximum technically possible production of a wind turbine. It should be noted that wind turbines are not principally designed for an optimal capacity factor, but to generate as much electricity as possible at certain wind speed. Capacity factors of 30-40% are considered very high for coastal areas.

^{2} The full load hours represent the capacity factor. It is the theoretical number of hours that the wind turbine has to run at full load in order to produce the annual yield (= capacity factor * number of hours in a year [8'760]).

^{3} Operating hours are the expected number of hours a year the wind turbine produces electricity. A year totals 8'760 hours.
